What are your go-to tools/books/blogs for cloud?

I'm looking for some practical, reusable cloud solutions. I'm a backend developer; however, sometimes, I have to create a new service using AWS services. Terraform is good in general.

My main problem is I sometimes miss a small detail which causes a production issue. It happened 2-3 times in the past few years.

Is there any good tool or practical book/blog to help me? I found a couple of Terraform generator solutions, but those are basic. Most blog posts I've checked describe the high-level concepts and don't go into details.

Any suggestions? Thanks in advance.
