The AWS Developer Associate (DVA-C02) and the Azure Developer Associate (AZ-204) are the same job on two different clouds: proving you can build, deploy and debug applications on the platform. The decision is rarely about which exam is “better” in the abstract; it is about the platform your employers use and where you write code. Here is the detailed comparison, beyond the table above.
The core difference
The AWS Developer Associate is about building cloud-native applications on AWS: serverless with Lambda and API Gateway, data stores like DynamoDB, deployment and CI/CD, security with IAM, KMS and Cognito, and troubleshooting with CloudWatch and X-Ray. It assumes you ship code that uses AWS services well.
The Azure Developer (AZ-204) is about building on Azure: compute through App Service, Functions and containers, storage with Blob and Cosmos DB, security via Microsoft Entra and Key Vault, connecting services through API Management, Event Grid and Service Bus, and monitoring with Application Insights.
So the split is purely platform: the same developer role, the same kinds of skills, expressed in different service names. If you already know which cloud you build on, the choice is largely made.
Cost compared
The two are close on price. The AWS Developer Associate exam is US$150; AZ-204 is around US$165, though pricing varies by country, so confirm current pricing with Microsoft. Neither has a prerequisite or education barrier.
Preparation can be free on both sides: AWS Skill Builder and the official exam guide on the AWS side, and the free Microsoft Learn study guide plus a free Azure account on the Azure side. The meaningful “cost” for either is hands-on time building something real rather than money. Renewal carries no fee on either platform, so cost should not be the deciding factor.
Difficulty and time
Both are demanding because both assume genuine development experience, not just concept recall.
- AWS Developer Associate is 65 questions in 130 minutes, passing at 720/1000. It is rated intermediate, and AWS expects you to be comfortable reading code and understanding how applications call AWS services. With some AWS exposure, candidates often plan around 60-80 hours; new to AWS, closer to 100-130.
- AZ-204 is around 40-60 questions in about 120 minutes, passing at 700/1000, and can include case studies. Microsoft rates it as the more advanced of the two and recommends one to two years of development experience plus Azure experience; many candidates spend roughly 8-12 weeks part-time.
Neither is trivially easy. The AWS exam is pitched at intermediate level, while AZ-204 is positioned as advanced and assumes more prior development experience, but in both cases the fastest route is writing code against the SDKs in a free account.
Ecosystem and job market
Job postings mirror the platform split.
- AWS has the largest overall public-cloud market share, and its certifications are among the most widely referenced, especially at startups, AWS-first companies and across much of the global tech market. The Developer Associate is the more portable single credential and often pairs with the Solutions Architect Associate.
- Azure is the default in many large enterprises, the public sector, and a large share of German, Austrian and Swiss companies already running Microsoft 365 and Windows Server. In those markets AZ-204 maps directly onto how teams build, and it pairs naturally with AZ-104 or AZ-400.
Demand for cloud developers exists everywhere, but in different proportions by region and industry. Look at the actual employers you are targeting and follow their stack.
Career outcomes
- AWS Developer Associate maps to: cloud or backend developer, DevOps engineer and application engineer roles on AWS. It commonly follows or pairs with the Solutions Architect Associate, with the DevOps Engineer Professional as a later step.
- AZ-204 maps to: developer and software-engineering roles in Azure-using organisations, with AZ-400 (DevOps) a common next step and AZ-305 covering the architect path.
Pay tracks the role, market and your engineering ability rather than the badge; both are associate-level developer credentials in a similar band. Multi-cloud literacy is increasingly valued, so some developers add the second platform later, but going deep on one first is the usual route.
How to decide
Choose by platform first, because that decides more than any feature.
- You build on AWS, or want the single most portable cloud developer credential → AWS Developer Associate.
- You build on Azure, or work in a Microsoft-centric organisation or region (common across DACH and Europe) → AZ-204.
- You have no preference at all → AWS is the safer default on market size and portability; AZ-204 is the better bet in a Microsoft-heavy context.
Whichever you pick, the core patterns (serverless, storage, identity, messaging and monitoring) transfer, so the second platform is much faster to learn later. And because both exams assume real development experience, the project you can actually show is what turns the interview into an offer.
