Could you please give me (a person who just started learning and using AWS) few tips and advices about how to become AWS professional and other info that you think it is important for me to know?

I have good prior programming experience with Python and R, and mostly work in data science projects.

Thank you.

Properly done AWS is always infrastructure as code, so learn CDK. Becoming proficient in building services where everything is wired by CDK will basically force you to understand the operating model of AWS and the building blocks. You essentially have:

IAM/Security -> Grant access between services

Networking/VPC -> Open interfaces between services

Services themselves -> S3/DynamoDB/Lambda

From there, you realize everything kinda follows the same pattern, and you can rely on the CDK typescript type system to chain and link things together.

From there, focus on microservice architectures, distributed coordination of writes to Dynamo DB from lambdas, when to use containers, etc

Thank you so much! Your comment opens eys on many things in AWS for me and is very valuable.
