If you're just getting started with AWS as a developer, it's best to begin with the core services that you'll use most often. Focus first on EC2 (for running virtual servers), S3 (for storing files), and RDS or DynamoDB (for databases). Once you're comfortable with those, explore Lambda for serverless functions, API Gateway for building APIs, and IAM for managing access and security.

To learn effectively, I recommend using AWS Skill Builder, which offers free learning paths and hands-on labs. You can also check out AWS Workshops and Serverless Land for practical tutorials that walk you through real-world use cases.

If you're interested in certifications, the AWS Certified Cloud Practitioner is a great starting point. After that, the AWS Developer Associate certification is more hands-on and focused on skills relevant to coding and building applications.

As a first project, try building something small like a to-do app using Lambda, API Gateway, and DynamoDB. It’s a great way to see how these services work together without getting overwhelmed. Once you complete that, you’ll have a solid foundation to build more complex applications.
