Unlike stateless applications that do not retain data between sessions, many enterprise applications require persistent storage to maintain state, such as databases, caches, and messaging systems. OpenShift Container Platform addresses this need through integration with various persistent storage technologies.

OpenShift supports dynamic provisioning of persistent volumes (PVs), enabling applications to request storage resources on demand. Persistent volume claims (PVCs) allow pods to bind to these storage resources, abstracting the underlying storage infrastructure.

Storage backends compatible with OpenShift range from local storage, network-attached storage (NAS), to cloud-based storage solutions such as Amazon EBS, Google Persistent Disk, and Red Hat’s own GlusterFS or Ceph. This flexibility allows organizations to tailor storage solutions to their performance, redundancy, and cost requirements.

Moreover, OpenShift supports stateful sets, a Kubernetes workload API object designed to manage stateful applications. Stateful sets provide stable network identities and persistent storage management for pods, ensuring data consistency and durability even when pods are rescheduled or replaced.

Routing Layer: Managing External Access and Traffic Flow

The routing layer in OpenShift Container Platform plays a critical role in managing inbound and outbound traffic for applications deployed within the cluster. It facilitates external access to internal services by acting as a gateway that routes requests to the appropriate application pods.

At the core of this layer are ingress controllers, which interpret routing rules and manage HTTP(S) traffic. OpenShift uses routers based on HAProxy to distribute client requests efficiently across multiple application instances, enhancing load balancing and failover capabilities.

The routing layer also supports advanced features such as TLS termination, enabling secure communication via HTTPS. It can enforce traffic policies, including path-based routing, host-based routing, and traffic splitting for canary deployments or blue-green releases.

Load balancers complement ingress controllers by distributing network traffic across worker nodes, ensuring that no single node becomes a bottleneck. This setup enhances performance and reliability by providing redundancy and fail-safe mechanisms.

Together, the routing components empower organizations to deliver scalable, secure, and resilient applications accessible to end-users, regardless of their geographic location or network conditions.
