I'm starting to learn AWS. I have experiences with spring cloud and i am wondering if it makes sense to use it within aws. opinions?

If you’re very comfortable with Spring Cloud, I really can’t say why it wouldn’t make sense to do so. I literally just googled what Spring Cloud is, so I can’t really say much more about it..

What I do recommend, if you can work in a cloud native way, is that you use AWS services for everything you can and write the least amount of code. That means going serverless and event-driven. Maybe look into AWS SAM and CDK? There are a ton of good resources out there to get stuff working in AWS in a cloud native well architected way. Since you are a dev, I trust you have the googling skills to find them.
