Microsoft Certified Azure Developer Associate AZ-203 Training Course

AZ-203, Developing Solutions for Microsoft Azure, was the original exam for the Azure Developer Associate certification. Microsoft has since retired AZ-203 and replaced it with AZ-204, which covers the same core developer skill set with updated content.

What AZ-203 Originally Covered

• Developing Azure compute solutions using App Service, Functions, and containers
• Developing for Azure storage, including Blob Storage and Cosmos DB
• Implementing security for applications, including authentication and authorization
• Monitoring, troubleshooting, and optimizing Azure solutions

What Changed with AZ-204

• AZ-204 reflects newer Azure services and updated best practices
• Anyone pursuing the Azure Developer Associate certification today should prepare for AZ-204, not AZ-203
• Core skill areas remain similar — compute, storage, security, and monitoring — but with refreshed exam objectives

Training Course Focus Areas

• Hands-on labs deploying applications to Azure App Service and Functions
• Working with Azure SDKs and REST APIs for common Azure services
• Implementing caching, messaging, and event-driven architectures
