The AWS Certified Developer Associate (DVA-C02) validates the ability to develop, deploy, and debug cloud-native applications on AWS. It targets working software engineers who write code against AWS services daily — Lambda, API Gateway, DynamoDB, S3, SQS/SNS, EventBridge, ECS, and the AWS SDKs. The exam emphasizes practical developer concerns: SDK usage, IAM roles for applications, deployment with CodePipeline/CodeBuild/CodeDeploy and SAM/CDK, observability, and cost-aware patterns. DVA-C02 launched in February 2023, refreshing DVA-C01 to reflect modern serverless practices, container deployment options, and updated CI/CD tooling. The exam is conceptual (no labs) but written to favor candidates who have actually shipped AWS code.
The largest domain at 32%. Lambda runtimes and limits, API Gateway integrations, DynamoDB data modeling, S3 SDK patterns, SQS/SNS/EventBridge messaging, and Step Functions. Tests practical code-level fluency.
IAM for applications (execution roles, instance profiles, STS, Cognito user/identity pools), KMS, Secrets Manager vs. Parameter Store. Common stumbling block: the boundary between Cognito user pools (authentication) and identity pools (authorization).
SAM, CDK, CloudFormation, CodePipeline, CodeBuild, CodeDeploy deployment strategies (canary, linear, all-at-once), and Lambda versions/aliases. Often missed: which deployment strategy belongs in which CodeDeploy compute platform.
CloudWatch Logs Insights, X-Ray tracing, Lambda cold-start mitigation, DynamoDB read/write capacity tuning, and caching patterns. Smallest domain (18%) but high signal for working developers.

DVA-C02 is the standard AWS credential for backend and full-stack engineers working on AWS-centric stacks. Recruiters use it as a fast filter alongside SAA-C03 — together they form the most common "two cert" combination on cloud-engineer resumes. It pairs naturally with the CloudOps Engineer Associate (SOA-C03) to complete the AWS associate trifecta and is a useful prerequisite-by-convention for the DevOps Engineer Professional (DOP-C02). The cert does NOT by itself qualify candidates for staff or principal engineering titles, nor for specialty roles in security, networking, or ML — those expect SAP-C02, specialty certs, or domain-specific shipped work.
There are no formal prerequisites. AWS recommends at least one year of hands-on experience developing applications on AWS, including comfort with at least one programming language (typically Python, JavaScript/TypeScript, Java, or Go) and the corresponding AWS SDK.
Most candidates approach DVA-C02 either after CLF-C02 (for AWS context) or after SAA-C03 (for architectural breadth). SAA-C03 first is the most common path because the architectural foundation makes DVA-C02 feel narrower and faster. Candidates from a strong general software-engineering background with limited AWS exposure should plan extra time on IAM nuances, the deployment toolchain (SAM/CDK/CodeDeploy), and DynamoDB single-table design.
DVA-C02 is rated Associate and sits at moderate difficulty — broadly comparable to SAA-C03 but narrower in scope and more code-flavored. Plan 60–90 hours over 6–10 weeks for candidates with some AWS development experience; 100–140 hours for engineers new to AWS. The exam is 65 scored questions in 130 minutes — multiple-choice and multiple-response, no hands-on labs.
Common stumbling blocks include CodeDeploy deployment strategies and how they differ across EC2, Lambda, and ECS targets; Lambda concurrency and provisioned-concurrency math; DynamoDB partition-key design and GSI behavior; and the precise boundary between Cognito user pools and identity pools. Practicing with the AWS CLI and SDK on a small personal project is the highest-ROI preparation activity.
Current version. Modernized coverage of serverless, container deployment, CDK, and observability. Removed deprecated services and tightened IAM-for-applications focus.
Retired in early 2023. Heavier on EC2-era patterns; lighter on serverless and CDK.
DVA-C02 (AWS Certified Developer Associate) is a a moderately difficult exam expecting practical hands-on experience plus solid understanding of best practices Associate-level exam. Most candidates need 80–150 hours of study spread over 6–12 weeks for associate-level exams. Most candidates who score consistently above the passing threshold on practice exams pass on their first attempt.
