> building highly scalable distributed system

I doubt that. Looking through the link and recently having discussed this in an OT-thread of an hobbyist-forum, the only thing you learn is AWS-lego. I don't see, how training for marketing keyword-riddled multiple choice-questions helps you in understanding the systems in question (case in point: Q1 of the "blog" - basically the only skill required is basic (!) logic matching requirements to the services (my mother can do this) and translating the marketing speech to requirements... – you don't need to know anything about interdependencies.)

At the end of the day, those that get hired because of their certificate can't actually take up budget resources and not be able to expertly talk about HA architecture and deliver on a technical roadmap. You can't hide behind a certificate. A technical professional actually needs to deliver a solution to a real-world business problem and when you don't it is highly visible. (Slow service, downtime, lost data, breaches)

If certification is indeed useless, and exams are simply basic marketing exams, it will eventually become a red flag in the hiring process.
