For what exactly?

AWS is a gigantic bundle of services. So the real question is: what you want to do?

The only real answer to such a nonspecific question is “Azure or GCP.” But to be honest, if the generic answer is what you’re looking for, you’d have been better off asking a search engine.

You should come back with a more specific ask, e.g. “I want to run my PHP application with a MySQL database, what do you use as an AWS alternative?”
