Overview of AZ-305: Azure Solutions Architect Expert

The AZ-305 exam, officially titled "Designing Microsoft Azure Infrastructure Solutions," is all about planning and designing Azure-based systems. It's aimed at people who want to become solutions architects think of them as the big-picture planners who ensure cloud setups meet business needs efficiently and securely.

This certification validates your ability to design solutions that run on Azure, covering everything from compute (like virtual machines) to storage and networking. It's not just about knowing the tools; it's about understanding how to put them together in a way that's scalable, reliable, and cost-effective. For instance, you might design a system that handles high traffic for an e-commerce site, ensuring it doesn't crash during peak times.

Who is this for? If you have advanced experience in IT operations, including networking, virtualization, identity management, security, and governance, this could be your fit. Microsoft recommends familiarity with Azure administration, development, and DevOps processes. You don't need a specific prerequisite certification, but real-world experience helps a lot.

Let's look at the skills measured in the exam. These are grouped into main categories, each with a percentage showing its weight:

• Design identity, governance, and monitoring solutions (25–30%): This includes managing user access with Microsoft Entra ID (Azure's identity service), setting up policies for compliance, and using tools like Azure Monitor to keep an eye on performance.
• Design data storage solutions (20–25%): Here, you'll plan how to store data using services like Azure Blob Storage or Azure SQL Database, considering factors like redundancy (backups) and security.
• Design business continuity solutions (15–20%): Focus on disaster recovery and high availability, such as using Azure Site Recovery to keep systems running even if something goes wrong.
• Design infrastructure solutions (30–35%): The biggest chunk, covering networking (virtual networks), compute resources (VMs, containers), and hybrid setups that mix on-premises and cloud.

The exam is available in multiple languages, including English, Japanese, and Spanish. It costs around $165 USD, depending on your location, and you need a score of 700 out of 1000 to pass. As of late 2024, the exam was updated to reflect the latest Azure features, so make sure your study materials are current.

In practice, passing AZ-305 means you can advise stakeholders— like business leaders—on how to build Azure solutions that align with frameworks like the Azure Well-Architected Framework. This framework is a set of best practices for building secure, high-performing systems. If you enjoy strategic planning and seeing the overall architecture, this certification will empower you to lead projects confidently.

Overview of AZ-400: Azure DevOps Engineer Expert

Shifting gears, the AZ-400 exam, "Designing and Implementing Microsoft DevOps Solutions," focuses on the DevOps side of things. DevOps is a way of working that combines software development (Dev) and IT operations (Ops) to deliver applications faster and more reliably. This certification is for those who want to automate processes and foster collaboration in teams.

Essentially, it validates your skills in creating pipelines for continuous integration (building code), continuous delivery (deploying it), and monitoring. Think of it as the engine that keeps software updates flowing smoothly, like how apps on your phone update seamlessly.

The target audience includes DevOps engineers who might come from development or infrastructure backgrounds. You need strong skills in Azure, GitHub, and Azure DevOps tools. Experience in cross-functional teams is key, as DevOps is about people and processes as much as technology.

Here are the skills measured, with their weights:

• Design and implement processes and communications (10–15%): This covers collaboration tools, agile practices (a flexible way to manage projects), and feedback loops.
• Design and implement a source control strategy (10–15%): Managing code with Git, branching strategies, and version control.
• Design and implement build and release pipelines (50–55%): The core of the exam—automating builds, tests, and deployments using Azure Pipelines or GitHub Actions.
• Develop a security and compliance plan (10–15%): Integrating security scans and ensuring regulatory compliance in the DevOps workflow.
• Implement an instrumentation strategy (5–10%): Setting up monitoring and logging to track application performance.

Like AZ-305, it's multilingual, costs about $165, and requires a 700 passing score. It was updated in July 2024, so check for the latest changes. To earn the full DevOps Engineer Expert title, you might need an associate-level cert like AZ-104 or AZ-305 as a prerequisite, but the exam itself stands alone.

This certification emphasizes practical implementation, such as setting up automated tests to catch bugs early. If you're into coding, automation, and making teams more efficient, AZ-400 will give you the tools to excel in modern software delivery.

Key Differences Between AZ-305 and AZ-400

While both certifications are expert-level and deal with Azure, they serve different purposes. AZ-305 is more about designing the foundation—the infrastructure that supports applications. It's like being the architect who draws the blueprints for a building. On the other hand, AZ-400 is about the processes that build and maintain that building over time, focusing on automation and collaboration.

One major difference is the focus area. AZ-305 dives deep into infrastructure design, such as choosing the right storage for data lakes or setting up virtual networks for secure connectivity. It requires understanding how decisions in one area, like security, impact the whole solution.

In contrast, AZ-400 is pipeline-heavy. Over half the exam is on build and release processes, where you learn to automate deployments so code changes go live quickly and safely. It's less about "what" to build and more about "how" to build and deliver it repeatedly.

Audience-wise, AZ-305 suits those with broad IT experience who enjoy strategic roles, advising on architecture. AZ-400 appeals to hands-on engineers who code scripts, manage repositories, and optimize workflows.

Another angle is career alignment. If you're interested in cloud architecture that spans multiple services, AZ-305 opens doors to roles where you design scalable systems. AZ-400, however, is ideal for DevOps environments, where speed and reliability in software delivery are paramount.

Both require Azure knowledge, but AZ-305 leans toward governance and continuity, while AZ-400 emphasizes security in pipelines and instrumentation. Overlapping areas, like monitoring, exist, but the approach differs AZ-305 for overall system health, AZ-400 for application-specific feedback.

In 2025, with cloud adoption accelerating, these differences matter. Businesses need architects to plan migrations and engineers to automate operations. Understanding this helps you pick based on your strengths.
