The #1 reason I would advocate for using AWS today is the compliance package they bring to the party. No other cloud provider has anything remotely like Artifact. I can pull Amazon's PCI-DSS compliance documentation using an API call. If you have a heavily regulated business (or work with customers who do), AWS is hard to beat.

If you don't have any kind of serious compliance requirement, using Amazon is probably not ideal. I would say that Azure AD is ok too if you have to do Microsoft stuff, but I'd never host an actual VM on that cloud.

Compliance and "Microsoft stuff" covers a lot of real world businesses. Going on prem should only be done if it's actually going to make your life easier. If you have to replicate all of Azure AD or Route53, it might be better to just use the cloud offerings.

I was going to post the same comment.

Most of the people agreeing to foot the AWS bill do it because they see how much the compliance is worth to them.
