I didn't say avoid AWS... I was more trying to point out that consultants and what not with certifications and "experience" are great at regurgitating information but often lack personal experience and result of their work months down the line. They suggest using tools based on their understanding, which is frequently with minimal hands-on experience... E.g. use a bunch of Dynamo DB tables with several indexes each to get serverless database.. ignoring concepts of duplicating data and leveraging hash/range, avoiding scans.. etc. (As an example)
