I think the difference is that AWS doesn't have seven frameworks for the same thing.. there certainly different levels to their services, but they generally are abstracting away the lower end each time they make a new product in a category.. There isn't really two different EC2-like systems, or two different S3 products, there's a new "popular" JS UI framework every year, and if you're still using the older framework 4 years later, it likely needs a heavy rework to upgrade to the latest version. I "learned" SQS 6 years ago, now I just keep up with the minor feature releases.. same with S3, and Lambda. In the same time I've looked at 4 different UI frameworks that have no overlap but try to do the same and result. Their services exist and they work.. and generally a guide from 5-10 yeas ago is still valid today (though the UI might be different, but the content remains reasonably valid)..
