This specialty-level credential is a validation of your subject matter expertise in creating, deploying, and maintaining SAP solutions on the Microsoft Azure platform. It signifies your ability to partner effectively with cloud administrators, database administrators, and clients to architect and implement robust and scalable SAP landscapes in the cloud.
Throughout this five-part guide, we will deconstruct the key knowledge domains of the AZ-120 exam. Our approach is to provide a structured learning path using publicly available information and official documentation, ensuring you can prepare thoroughly without the need for paid content. In this initial installment, we will focus on the foundational pillars: planning your SAP on Azure deployment, selecting the appropriate virtual machines and storage, and designing a network architecture that meets the stringent demands of SAP workloads. A solid understanding of these core infrastructure components is the first and most critical step toward success.
The Microsoft Certified: Azure for SAP Workloads Specialty certification is not an entry-level exam. It is intended for architects and engineers who have extensive experience and knowledge of the SAP platform, including NetWeaver, S/4HANA, SAP HANA, and SAP Business Suite. Candidates should also possess strong skills in Azure administration, including virtualization, networking, storage, and security. The exam measures your ability to migrate SAP workloads to Azure, design and implement solutions for optimal performance and reliability, and manage and monitor these environments to ensure they adhere to service level agreements and business requirements.
Earning this certification demonstrates a deep understanding of the nuances involved in running mission-critical SAP systems on a hyperscale cloud platform. It validates that you can make informed decisions about infrastructure components, high availability and disaster recovery strategies, and identity management. The exam covers a broad range of topics, from the specifics of storage performance for HANA databases to the configuration of cross-premises network connectivity. This series will break down these topics into manageable sections, starting with the essential planning and implementation of core Azure services.
Before deploying any resources, a successful SAP on Azure project begins with meticulous planning. The Azure platform offers a vast array of services, and choosing the right combination is key to a successful implementation. The planning phase involves assessing the existing SAP landscape, defining performance and availability requirements, and mapping these to the appropriate Azure services. This process ensures that the deployed environment is cost-effective, scalable, and meets the technical prerequisites set by both SAP and Microsoft. It is crucial to consult the official SAP on Azure documentation for the latest certified configurations and support notes.
This initial planning and implementation guide is your starting point. It helps you understand how Azure enables companies to acquire compute and storage resources rapidly, avoiding lengthy traditional procurement cycles. The flexibility of the cloud allows you to deploy classic SAP NetWeaver-based applications and enhance their reliability without needing additional on-premises hardware. A well-thought-out plan will consider compute, storage, and networking in tandem, as these components are deeply interconnected and their proper configuration is vital for the performance of your SAP systems.
The compute layer, provided by Azure Virtual Machines, is the heart of your SAP application and database tiers. Not all Azure VM types are certified for SAP workloads. Microsoft provides specific VM families that are tested and certified to meet the performance standards required by SAP NetWeaver and SAP HANA. For the SAP application layer, various general-purpose and memory-optimized VMs are suitable. However, for in-memory databases like SAP HANA, you must use VMs from the M-series or E-series families, which are specifically designed and certified for these demanding workloads.
When selecting a VM, you must consider factors such as the number of vCPUs, the amount of RAM, and the maximum supported storage throughput and IOPS. The official SAP on Azure documentation contains a list of all certified VM types for both SAP NetWeaver and SAP HANA. It is essential to refer to this list during your planning phase to ensure your chosen architecture is fully supported. Using unsupported VM types can lead to performance issues and may not be supported by SAP or Microsoft, putting your mission-critical systems at risk.
Network architecture is a critical component of any SAP on Azure deployment. A properly designed network ensures secure, reliable, and low-latency communication between your SAP systems, your on-premises environment, and your end-users. The foundation of your network in Azure is the Virtual Network (VNet). A VNet provides an isolated environment where you can run your VMs and applications. Best practices dictate segmenting your VNet into multiple subnets to logically separate your SAP landscape tiers, such as the database, application, and web dispatcher subnets.
Security is enhanced by using Network Security Groups (NSGs) to filter traffic between these subnets. NSGs act as a basic firewall, allowing you to define rules that permit or deny network traffic based on source and destination IP addresses, ports, and protocols. For example, you can create rules to ensure that only the application servers can communicate with the database servers on the specific SAP database port. This layered security approach, known as defense-in-depth, is crucial for protecting your sensitive SAP data.
Most enterprise SAP deployments in Azure operate in a hybrid model, requiring seamless connectivity back to the corporate on-premises network. Azure provides two primary services for establishing this cross-premises connectivity: Azure VPN Gateway and Azure ExpressRoute. A VPN Gateway uses the public internet to create a secure, encrypted tunnel between your on-premises network and your Azure VNet. This is a good option for smaller deployments, development or test environments, or scenarios where the highest level of performance is not a strict requirement.
For production SAP workloads, Azure ExpressRoute is the recommended solution. ExpressRoute provides a private, dedicated connection between your on-premises data center and the Azure cloud, bypassing the public internet entirely. This results in lower and more consistent latency, higher bandwidth, and enhanced security compared to a VPN connection. Establishing this connectivity is a foundational step, as it enables the integration of your Azure-based SAP systems with your on-premises domains, private clouds, and the broader SAP system landscape within your organization.
Azure offers a diverse range of storage types, each with different capabilities, performance characteristics, and pricing models. For SAP workloads, selecting the correct storage is paramount, as database performance is heavily dependent on storage latency and throughput. The primary storage type used for SAP database servers is Azure Managed Disks. These are block-level storage volumes managed by Azure and used with Azure Virtual Machines. Within Managed Disks, Azure offers several performance tiers, and it is crucial to understand which ones are suitable for SAP.
The main tiers to consider are Standard HDD, Standard SSD, Premium SSD, and Ultra Disk. For any production SAP system, particularly the database layer, only Premium SSD and Ultra Disk are supported and recommended. Premium SSDs provide a balance of high performance and cost-effectiveness, with IOPS and throughput guarantees based on the disk size. Ultra Disks offer the highest performance with configurable IOPS and throughput, and sub-millisecond latency, making them ideal for the most demanding SAP HANA database log volumes.
When designing the storage layout for an SAP system, you need to consider the different requirements of the operating system, the database data files, and the database log files. The OS disk has modest performance requirements and can typically use a smaller Premium SSD. The database data files require high IOPS and throughput, making larger Premium SSDs or Ultra Disks the appropriate choice. The database transaction log files have the most stringent requirement for low latency, making Azure Ultra Disk the optimal solution for production SAP HANA systems.
In addition to Managed Disks, Azure also offers file storage solutions like Azure NetApp Files. Azure NetApp Files is a high-performance, enterprise-grade file storage service that is certified for use with SAP HANA. It is often used for shared file systems in high-availability clusters or for the /hana/shared volume in SAP HANA scale-out deployments. Understanding the capabilities and use cases for both Azure Managed Disks and Azure NetApp Files is essential for designing a compliant and high-performing storage architecture for your SAP on Azure landscape.
Welcome to the second part of our series focused on preparing you for the Microsoft Certified: Azure for SAP Workloads Specialty exam. In the first installment, we established the foundational knowledge of core infrastructure components, including planning, virtual machines, networking, and storage. Now, we will take a deep dive into what is arguably the most critical component of any SAP landscape: the database layer. The performance, reliability, and scalability of your SAP system are fundamentally dependent on the proper deployment and management of its underlying database management system (DBMS).
In this article, we will explore the deployment of two primary database systems for SAP workloads on Azure: SQL Server and the in-memory powerhouse, SAP HANA. We will cover the best practices for configuring SQL Server on Azure VMs for SAP NetWeaver and then transition to a detailed examination of SAP HANA deployments. This includes architecting HANA on standard Azure VMs and understanding the unique characteristics of the purpose-built SAP HANA Large Instances. A thorough grasp of these database topics is absolutely essential for success on the AZ-120 exam and for your role as an SAP on Azure specialist.
When deploying an SAP system with a SQL Server database on Azure, there are several key areas to consider to ensure optimal performance and stability. It is generally recommended to use the most recent, SAP-certified releases of SQL Server. Newer versions often include performance enhancements and better integration with Azure services and infrastructure. For instance, recent releases have changes that optimize operations in an IaaS environment, which can translate to better performance and manageability for your SAP workload. Always verify the supported SQL Server versions for your specific SAP product version in the SAP Product Availability Matrix (PAM).
The configuration of the underlying Azure infrastructure is also critical. This includes selecting the correct VM type, which should be certified for SAP NetWeaver workloads, and designing a high-performance storage layout. For SQL Server, this means separating the data files (.mdf), log files (.ldf), and the tempdb onto different Azure Managed Disks. Using Azure Premium SSDs or Ultra Disks is mandatory for production systems to meet the IOPS and latency requirements of the database. Proper configuration of SQL Server settings, such as max memory and trace flags, is also necessary to align with SAP best practices.
SAP HANA is an in-memory, column-oriented, relational database management system that serves as the foundation for SAP's next-generation applications, including S/4HANA. Running SAP HANA on Azure requires a deep understanding of its stringent infrastructure requirements. Due to its in-memory nature, SAP HANA demands VMs with very large memory capacities and storage with extremely low latency, particularly for the transaction log writes. Microsoft Azure provides a range of SAP HANA certified infrastructure options to meet these needs, which can be broadly categorized into two deployment models: SAP HANA on Azure Virtual Machines and SAP HANA on Azure Large Instances.
Choosing between these models depends on the size of the HANA database and the specific business requirements. The majority of SAP HANA deployments on Azure are on certified VMs from the M-series and E-series families. These VMs offer a wide range of memory sizes, from smaller instances for non-production systems to massive VMs with several terabytes of RAM for large-scale production databases. For exceptionally large HANA databases that exceed the capacity of the largest available VMs, SAP HANA on Azure Large Instances provides a purpose-built, bare-metal infrastructure option.
When deploying SAP HANA on Azure VMs, meticulous attention to the architecture is required. The first step is selecting a VM from the official list of SAP HANA certified hardware. These VMs have been rigorously tested to ensure they provide the necessary performance and stability. The next critical step is designing the storage configuration. A key component of this is the use of a feature called Write Accelerator for the disks hosting the /hana/log volume. Write Accelerator is a feature available for M-series VMs that provides sub-millisecond latency for log writes, which is a strict prerequisite for SAP HANA.
The storage layout must be carefully planned. The /hana/data and /hana/log volumes must be on separate high-performance disks, typically Premium SSD or Ultra Disk. The size of these disks determines their performance characteristics (IOPS and throughput), so you must select a disk size that meets the Key Performance Indicators (KPIs) defined by SAP's HANA Hardware Configuration Check Tool (HWCCT). Furthermore, the /hana/shared volume, which is used in scale-out and high-availability setups, is often placed on a high-performance NFS share provided by a service like Azure NetApp Files.
SAP HANA on Azure Large Instances, also known as BareMetal Infrastructure, is a specialized solution designed for the largest and most demanding SAP HANA workloads. Unlike standard Azure VMs, which are multi-tenant and virtualized, HLI provides dedicated, physical servers located in an Azure data center. This bare-metal approach eliminates the virtualization layer, offering maximum performance for customers with exceptionally large HANA databases, often exceeding 20 terabytes of memory. These instances are integrated into the Azure ecosystem, allowing for low-latency connectivity to applications running on standard Azure VMs.
HLI is offered in different SKUs, or "classes," which are categorized based on their intended use. Type I class instances are designed for a broad range of HANA workloads and come with a storage volume that is typically four times the memory volume. Type II class instances are aimed at even larger scale-out deployments and come with additional storage intended for storing HANA transaction log backups. Understanding the distinction between these classes and the specific use cases for HLI is an important topic for the Microsoft Certified: Azure for SAP Workloads Specialty exam.
The storage architecture for SAP HANA on Azure Large Instances is distinct from the storage used with Azure VMs. It is an all-flash storage solution provided by a high-performance Network File System (NFS) infrastructure. The storage layout is pre-configured by the service automation according to SAP's recommended guidelines, so you do not have to design it yourself. When an HLI unit is provisioned, it comes with pre-mounted volumes for /hana/data, /hana/log, /hana/shared, and /usr/sap. This standardized configuration ensures that the storage meets the strict performance KPIs required by SAP HANA.
It is crucial to understand that this is not standard Azure storage. You cannot attach Azure Managed Disks to an HLI unit. Instead, you work with the provided NFS volumes. The storage infrastructure also includes capabilities for creating storage snapshots. These snapshots are a key component of the backup and restore strategy for HLI. They provide a mechanism for creating fast, application-consistent backups of the HANA database, which can be used for quick restores in case of a logical error or data corruption.
The network architecture for SAP HANA on Azure Large Instances is designed to provide high-throughput, low-latency connectivity between the HLI units and the Azure VMs running the SAP application layer. The HLI units are located in an "HLI stamp," which is a collection of servers and storage isolated within an Azure region. This stamp is connected to the main Azure network fabric via ExpressRoute circuits. When you deploy an HLI solution, an ExpressRoute circuit is provisioned to connect your Azure VNet to the HLI stamp.
This ExpressRoute connection is crucial. All network traffic between your application servers (on VMs) and your HANA database (on HLI) flows over this dedicated, private connection. This ensures the communication path is optimized for the high volume and latency-sensitive traffic characteristic of SAP workloads. Understanding this network topology is essential for troubleshooting connectivity issues and for properly configuring the network routing between your VNet and the HLI environment.
Proper network routing is critical for a functioning SAP HANA on Azure Large Instances deployment. There are three key routing considerations. First, you need to ensure that the application servers running on VMs in your Azure VNet can reach the HLI unit's IP address. This is achieved by using the ExpressRoute Gateway in your VNet, which learns the routes to the HLI IP address range and propagates them to the VMs in the VNet. Second, the HLI unit itself must be able to route back to the VMs in the Azure VNet.
The third, and often more complex, consideration is routing from your on-premises network to the HLI unit. To enable this, you must use a feature called ExpressRoute Global Reach. Global Reach allows you to link two ExpressRoute circuits together, creating a private network path between your on-premises data center and the HLI stamp, effectively connecting your on-premises network directly to your HANA Large Instance for administrative or data replication purposes. Mastering these routing concepts is a key aspect of managing an HLI environment.
Welcome to the third installment of our comprehensive study guide for the Microsoft Certified: Azure for SAP Workloads Specialty certification. In the preceding parts, we established a strong foundation in core Azure infrastructure and delved into the intricacies of managing database systems for SAP. Now, we turn our attention to one of the most critical aspects of running enterprise-grade workloads: high availability (HA) and disaster recovery (DR). For mission-critical SAP systems, downtime is not an option, and having a robust business continuity strategy is paramount.
This article will guide you through the principles and practices of designing and implementing resilient SAP architectures on Azure. We will explore the reference architectures for achieving high availability for both the SAP application and database tiers. We will take a close look at specific HA configurations for SAP HANA using features like HANA System Replication (HSR). Furthermore, we will examine how Azure Site Recovery can be leveraged to build a comprehensive disaster recovery solution. A deep understanding of these HA/DR concepts is a cornerstone of the AZ-120 exam and a vital skill for any SAP on Azure architect.
Microsoft provides a reference architecture for running SAP NetWeaver in a high-availability configuration on Azure. This architecture is designed to provide redundancy at every layer of the SAP landscape to eliminate single points of failure. At the database layer, this typically involves using database-native replication technologies, such as SQL Server Always On or SAP HANA System Replication, configured across two VMs in different Azure Availability Zones. Availability Zones are physically separate locations within an Azure region, providing protection against data center-level failures.
For the SAP application layer, high availability is achieved by deploying multiple application servers. The SAP Central Services (ASCS) instance, which is a single point of failure, is protected using a Windows Server Failover Cluster or a Linux Pacemaker cluster. The cluster manages a shared disk resource and a virtual IP address that can float between the two cluster nodes. This ensures that if the active ASCS node fails, the services are automatically started on the passive node, minimizing downtime. This reference architecture, with specific VM sizes, can be adapted to meet the needs of any organization.
For SAP HANA, the primary mechanism for achieving high availability is HANA System Replication (HSR). HSR is a feature of SAP HANA that continuously replicates the in-memory database from a primary node to a secondary node. The replication can be configured in either synchronous or asynchronous mode. For high availability within a single Azure region, synchronous replication is used between two HANA VMs deployed in different Availability Zones. This ensures that a transaction is not considered committed until it has been written to the log on both the primary and secondary nodes, guaranteeing zero data loss (RPO=0).
To manage the automatic failover of the HANA database, a cluster solution is required. On SUSE Linux Enterprise Server (SLES) or Red Hat Enterprise Linux (RHEL), this is typically achieved using a Pacemaker cluster. The cluster is configured with specific resource agents for SAP HANA that monitor the health of the HANA instances. If the cluster detects a failure on the primary node, it will automatically trigger a takeover on the secondary node, promoting it to become the new primary and redirecting client connections.
The high-availability principles for a single-node (scale-up) SAP HANA system can be extended to a multi-node (scale-out) configuration. In a scale-out deployment, the HANA database is distributed across multiple server nodes to handle larger data volumes. Achieving high availability for a scale-out system also relies on HANA System Replication and a Pacemaker cluster on SUSE Linux Enterprise Server. The entire scale-out cluster on the primary site is replicated to a corresponding scale-out cluster on the secondary site. Both sites must have the same number of nodes.
A key component of this architecture is the shared file systems, such as /hana/shared. These file systems must be highly available and accessible from all nodes in the cluster. In Azure, this is typically achieved by using a high-performance, NFS-based solution. The presented architecture often uses Azure NetApp Files or an NFS share on Azure Files to provide these resilient, shared file systems. The Pacemaker cluster is configured to manage the failover of the entire scale-out system from the primary site to the secondary site in the event of a disaster.
While high availability protects against failures within a single Azure region, disaster recovery is about protecting your systems from a large-scale regional outage. Azure Site Recovery is the primary Azure-native service for implementing a DR strategy for Azure VMs. It provides a mechanism for continuously replicating your virtual machines from a primary Azure region to a secondary Azure region. For SAP workloads, this allows you to replicate your entire landscape, including the application and database servers, to a different geographic location.
Azure Site Recovery manages the orchestration of this replication. You define replication policies, create recovery plans to specify the order in which VMs should be failed over, and can perform non-disruptive DR drills. If a disaster occurs in the primary region, you can initiate a failover. This action brings up the replicated VMs in the secondary region, allowing you to resume business operations. Once the primary region is restored, Azure Site Recovery also provides capabilities to fail back your workloads to their original location.
The architecture for Azure-to-Azure disaster recovery using Azure Site Recovery involves several key components. In the primary region, you have your production SAP virtual machines. You deploy a Recovery Services vault, which is the management entity for your DR activities. You then enable replication for each of the SAP VMs. When you enable replication, the Site Recovery mobility service extension is installed on the VMs, and it begins to replicate all disk writes to a cache storage account in the primary region.
From the cache storage account, the data is sent to a storage account in the secondary (DR) region. In the DR region, Site Recovery uses this replicated data to create recovery points, which are stored on managed disks. These recovery points can be crash-consistent or application-consistent. When you initiate a failover, Site Recovery uses these managed disks to create new virtual machines in the secondary region based on the replicated data. The entire process is designed to be automated and reliable, providing a robust solution for regional disaster recovery.
One of the most powerful features of Azure Site Recovery is the ability to conduct disaster recovery drills without impacting your production environment. This is done by executing a test failover. A test failover allows you to validate your entire replication and DR strategy, ensuring that your systems will come online as expected in a real disaster scenario. This process does not cause any data loss or downtime for your production workloads. When you initiate a test failover, Site Recovery creates a new, isolated virtual network in the secondary region.
It then creates a copy of your replicated VMs and attaches them to this isolated test network. This allows you to start the VMs, connect to them, and perform application-level testing to verify that your SAP systems are functioning correctly. Because the test environment is completely isolated from your production network, there is no impact on ongoing replication or your end-users. After testing is complete, you can clean up the test failover environment with a single click, removing the created VMs and networks.
Welcome to the fourth part of our in-depth series preparing you for the Microsoft Certified: Azure for SAP Workloads Specialty (AZ-120) exam. Having covered core infrastructure, database management, and business continuity, we now shift our focus to the practical aspects of migrating your SAP landscape to Azure and ensuring it runs at peak performance. The migration process for a complex platform like SAP is not trivial; it requires careful planning and the selection of the right methodology. Once migrated, continuous monitoring and optimization are key to operational excellence.
In this article, we will explore various migration options for moving SAP applications to Azure, with a special focus on the Database Migration Option (DMO). We will then delve into critical operational tasks, such as backup and restore procedures, and introduce powerful tools like the Azure Application Consistent Snapshot tool. Finally, we will discuss performance tuning, covering topics from accelerated networking to the use of monitoring tools. Mastering these migration and operational concepts is crucial for both the exam and for successfully managing a real-world SAP on Azure environment.
Migrating an SAP platform to Azure is a significant undertaking that goes beyond a standard server migration. SAP systems have strict technical, security, and compliance requirements that demand a specialized approach. The migration process should not be treated as a simple lift-and-shift operation handled by a standard migration factory. Instead, it requires a dedicated project with expertise in both SAP and Azure. The initial phase involves a thorough assessment of the existing landscape, identifying dependencies, and defining the target architecture in Azure.
The choice of migration methodology is a critical decision in the planning phase. The methodology will depend on several factors, including the source operating system and database, the target database in Azure (e.g., are you migrating to SAP HANA?), and the business tolerance for downtime. A comprehensive migration plan will outline the chosen approach, the sequence of events, testing cycles, and a rollback strategy. This plan becomes the blueprint for the entire migration project, ensuring all stakeholders are aligned and the project proceeds smoothly.
There are several established methodologies for migrating SAP systems to Azure. The "Classical Migration" approach, also known as a homogeneous or heterogeneous system copy, is a well-known method. This involves exporting the source SAP database and importing it into the target system in Azure. This method is reliable and flexible, supporting a wide range of source and target combinations. However, it can often involve significant downtime, as the export and import processes can be time-consuming for large databases.
An alternative and increasingly popular approach is the Database Migration Option (DMO) tool, which is part of the SAP Software Update Manager (SUM). DMO is a powerful tool that can combine a system update, a Unicode conversion, and a database migration into a single procedure. This can significantly reduce the overall project timeline and downtime compared to a classical migration. The choice between a classical approach and DMO depends on the specific requirements of the migration project.
The Database Migration Option (DMO) offers several advantages that can accelerate the migration of SAP systems to Azure. One of its key features is its ability to perform an in-place migration on the application server. The tool connects to the source database and the target database simultaneously, transferring the data directly between them. This can reduce the amount of downtime required, as much of the data transfer can happen while the source system is still running. This is a significant optimization compared to the export/import process of a classical migration.
A particularly powerful feature is "DMO with System Move." This option is designed specifically for migrations to a different data center, such as moving from on-premises to Azure. In this scenario, DMO handles the migration of the database to the target Azure environment while also preparing the application server for the move. This integrated approach simplifies the overall process and is a highly efficient way to move SAP systems to the cloud. Understanding the capabilities and use cases of DMO is a key topic for the AZ-120 exam.
Once your SAP system is running in Azure, establishing a robust backup and restore strategy is a critical operational task. This is especially true for SAP HANA on Azure Large Instances, which has a unique architecture. To ensure you can restore your HANA database to a consistent state, you must perform several types of backups. This includes regular full database backups, differential or incremental backups, and frequent transaction log backups. These backups are essential for point-in-time recovery in case of data loss or corruption.
The primary mechanism for backing up SAP HANA on Large Instances relies on storage snapshots. These snapshots provide a fast and efficient way to create a consistent image of the data and log volumes. The backup process involves coordinating with the SAP HANA database to create a database snapshot, then triggering a storage snapshot of the underlying volumes, and finally deleting the database snapshot. This procedure ensures the backup is application-consistent and can be used for a reliable restore.
To simplify and automate the process of creating application-consistent snapshots, Microsoft provides the Azure Application Consistent Snapshot tool (AzAcSnap). This command-line tool can be used with services like Azure NetApp Files and Azure Large Instances storage. AzAcSnap communicates with the SAP HANA database to put it into a consistent state before triggering a storage snapshot. It handles the entire workflow of quiescing the database, taking the snapshot, and then releasing the database, ensuring the snapshot is valid for recovery.
The tool is not just for backups; it also includes a restore command. The azacsnap -c restore command provides a guided process for restoring a database from a storage snapshot. It helps you mount the snapshot volumes and provides the necessary database commands to perform the recovery. Using a tool like AzAcSnap standardizes the backup and restore process, reduces the risk of human error, and is a key component of a well-managed SAP on Azure environment.
The network performance of your Azure VMs can have a significant impact on your SAP system's responsiveness and overall performance. The Azure networking stack maintains state for each TCP/UDP connection in data structures called flows. There is a limit to the number of active network flows a VM can handle at any given time. High-traffic SAP application servers can potentially exceed these limits, which can lead to performance degradation or connection drops. It is important to monitor network performance and choose a VM size that can support the expected network load.
The official Azure documentation provides guidance on the network flow limits for different VM sizes. When troubleshooting network performance issues, checking the network flow statistics is a crucial step. Ensuring your SAP systems are running on appropriately sized VMs with sufficient network capacity is a fundamental aspect of performance tuning in Azure.
To further enhance network performance, Azure offers a feature called Accelerated Networking. This feature enables single root I/O virtualization (SR-IOV) for a VM, which significantly improves its networking performance. Accelerated Networking bypasses the virtual switch in the host's virtualization stack, allowing network traffic from the VM to arrive directly at the host's network interface card. This path reduction lowers latency, reduces jitter, and decreases CPU utilization for network processing.
For all production SAP workloads on Azure, enabling Accelerated Networking is a mandatory prerequisite. It is a critical feature for achieving the low-latency and high-throughput network performance required by demanding SAP applications and databases. You can enable Accelerated Networking when creating a VM through the Azure Portal or by using tools like Azure PowerShell. Verifying that Accelerated Networking is enabled and functioning on your SAP servers is a key administrative task.
Welcome to the fifth and final part of our comprehensive guide to mastering the Microsoft Certified: Azure for SAP Workloads Specialty (AZ-120) exam. In our journey so far, we have built a solid understanding of Azure infrastructure, database management, high availability, migration, and performance tuning for SAP. In this concluding installment, we will address the critical areas of security and identity integration. We will also consolidate everything we have learned into a strategic plan for your final exam preparation.
This article will explore how to integrate your SAP environment with Azure Active Directory to enable Single Sign-On, a crucial step for modernizing user access. We will then provide a holistic view of security best practices for your SAP on Azure landscape. Finally, we will offer practical advice on how to approach the exam itself and discuss the significant career benefits that come with earning this prestigious specialty certification. This final piece will equip you with the knowledge and confidence needed to pass the AZ-120 exam and excel in your career.
In a modern enterprise, identity and access management are centralized to enhance security and improve user experience. Azure Active Directory (Azure AD) is Microsoft's cloud-based identity and access management service. Integrating your SAP applications with Azure AD allows you to leverage its robust security features and provide users with a seamless Single Sign-On (SSO) experience. Instead of juggling separate usernames and passwords for SAP, users can authenticate once with their corporate Azure AD credentials to access all their authorized applications, including SAP.
This integration is typically achieved using modern authentication protocols like SAML 2.0. Azure AD acts as the identity provider (IdP), and the SAP system, such as SAP Cloud Identity Services or SAP NetWeaver, is configured as the service provider (SP). When a user tries to access the SAP application, they are redirected to Azure AD for authentication. After successful authentication, Azure AD sends a security token back to the SAP system, which grants the user access. This simplifies user management and allows you to enforce consistent security policies, like Multi-Factor Authentication (MFA).
A common integration scenario involves configuring Azure AD SSO with SAP Cloud Identity Services. This service often acts as a proxy identity provider, federating with other identity providers like Azure AD. The configuration process involves establishing a trust relationship between the two systems. In Azure AD, you create an enterprise application for SAP Cloud Identity Services. You configure this application with the necessary SAML settings, such as the identifier (Entity ID) and the reply URL provided by the SAP service.
On the SAP Cloud Identity Services side, you configure a new corporate identity provider, providing it with the federation metadata from your Azure AD application. This metadata contains the necessary information, such as the public key, for the SAP service to trust the tokens issued by Azure AD. Once the trust is established, you can create a test user in both systems to validate the SSO configuration from end to end, ensuring a smooth and secure authentication flow for your users.
Securing an SAP landscape on Azure requires a multi-layered approach, often referred to as defense-in-depth. This starts with securing the underlying network. As discussed in Part 1, using Network Security Groups (NSGs) to segment your virtual network and restrict traffic between the different SAP tiers is a fundamental practice. You should only allow communication on the specific ports required by the SAP application. For enhanced security, you can also deploy Azure Firewall or third-party Network Virtual Appliances (NVAs) to inspect traffic and protect against threats.
Beyond the network, it is crucial to secure the virtual machines themselves. This includes practices like regular OS patching, using endpoint protection solutions like Microsoft Defender for Endpoint, and leveraging Azure security services. Microsoft Defender for Cloud provides security posture management and threat protection for your Azure resources. It can identify misconfigurations, assess vulnerabilities, and provide alerts for suspicious activities, giving you a centralized view of the security state of your entire SAP environment.
Proper governance of identities and access is critical to preventing unauthorized access to your sensitive SAP data. In Azure, this is managed through Role-Based Access Control (RBAC). Azure RBAC allows you to grant granular permissions to users, groups, and service principals, assigning them specific roles scoped to particular resources or resource groups. The principle of least privilege should always be applied, meaning users and services should only be granted the minimum level of access required to perform their functions.
For privileged access, you can use Azure AD Privileged Identity Management (PIM). PIM provides just-in-time (JIT) access to privileged roles, meaning users must request and justify their need for elevated permissions for a limited time. This reduces the risk associated with standing administrative access.
