An old AWS Machine Learning – Specialty study plan still contains useful technical ideas, even though its examination does not. AWS retired MLS-C01 after March 31, 2026, so new candidates cannot use a preparation checklist to book that exam. What can be reused is a structured set of projects that tests data preparation, exploratory analysis, […]

AWS Lambda and Amazon EC2 both run code, but they ask developers to accept very different operational responsibilities. EC2 provides virtual machine capacity with guest-operating-system and process control; Lambda provides managed function execution driven by requests or events. The difference affects application architecture, scaling, patching, observability, latency and the cost of idle resources. A useful […]

AWS Lambda runs application code when a request or event arrives without requiring a team to manage a traditional server fleet. The service provisions supported execution infrastructure, but it does not eliminate software engineering and operational work. A production function still needs a defined event contract, a suitable runtime, scoped credentials, downstream dependencies, error handling, […]

AWS Lambda can serve as a lightweight inference layer for some machine-learning models. An event or API request invokes a function, the code loads or accesses a suitable model, transforms the input, generates a prediction, and returns or stores the result. This can work well for bounded CPU-based tasks such as classifying a short text […]

Amazon Web Services Lambda, commonly known as AWS Lambda, is a highly popular cloud service that allows users to run code without managing servers or worrying about infrastructure. It supports multiple programming languages and operates on an event-driven model, making it ideal for building scalable and efficient cloud applications. Gaining a solid understanding of AWS […]

AWS re:Invent 2020 was a virtual, free-to-attend conference held across December 1–18, 2020. AWS promoted five keynotes, leadership sessions and hundreds of breakouts for developers, architects and operations professionals who could not attend an in-person event. This was a distinctive moment in cloud history, not a conference that can be registered for today. Readers revisiting […]

AI-900 is a retired exam. Microsoft retired Azure AI Fundamentals exam AI-900 on June 30, 2026. Its historical topics—machine-learning basics, computer vision, language and speech, generative AI and responsible AI—still make useful introductory exercises, but this article must not be treated as instructions for booking an exam that no longer exists. The current Azure AI […]

If you’re searching for DP-203 exam practice questions, you’ve come to the right place. Examlabs offers free sample questions that not only help you evaluate your readiness for the exam but also serve as an effective revision tool to reinforce critical concepts covered in the test. Azure Data Engineers hold a pivotal position in the […]

As the digital transformation accelerates across industries, the sheer volume of data being produced, collected, and stored has reached unprecedented levels. From user behavior on mobile applications to sensor outputs in IoT devices, the need to convert this massive influx of raw data into actionable insights has become paramount. This shift is significantly driving the […]

Building applications on Azure requires a small set of well-understood tools for editing code, testing locally, managing infrastructure, deploying safely and diagnosing failures. This article updates the older ExamLabs inventory, which mentioned legacy utilities and editor integrations that should not be presented as the default modern toolkit without current support verification. The goal is not […]

Azure has hundreds of services, but a useful quick reference should emphasize the categories and decisions a learner repeatedly needs. This concise guide connects subscriptions and resource groups to compute, networking, storage, identity, cost and operational evidence. It is a reference for choosing where to investigate, not a guarantee that one product is always appropriate […]

Microsoft Exam 70-534, Architecting Microsoft Azure Solutions, belongs to the earlier generation of Azure certifications. Microsoft replaced 70-534 with 70-535, and the wider MCSA/MCSE-era exam paths subsequently gave way to role-based qualifications. A reader searching for 70-534 preparation in 2026 needs this distinction immediately: the old examination is no longer a booking option, and historic […]

Exam 70-532, Developing Microsoft Azure Solutions, retired on December 31, 2018. The AZ-202 transition exam associated with eligible 70-532 holders retired March 31, 2019. This guide treats those assessments as historical and teaches transferable Azure developer skills, not a route to book an obsolete certification test. The retired 70-532 exam and its transition history Exam […]

Microsoft Exam 70-532, Developing Microsoft Azure Solutions, assessed an earlier model of Azure application development. It is retired, as are several later developer exams that replaced or followed it. A guide that advises readers in November 2026 to book 70-532, take AZ-202 as a live transition examination or pursue AZ-204 as an active certification would […]

Preparing for Microsoft AZ-305 should develop architecture judgment rather than recite an Azure service catalog. This guide is a practical study sequence with design exercises, validation questions and evidence of readiness. The separate AZ-305 certification overview explains the domain map; here the objective is to turn those domains into decisions an architect could defend to […]
