Is it worth getting professional certifications while in a job?
I am working in IT and some of my colleagues are talking about getting certifications for a particular domain within our field of work. These certifications are expensive and requires time and effort. So are they worth getting?
I did the most difficult aws certifications but turns out it doesn't matter - even the intro certs are seen as very valuable by hiring managers, the ones where you just learn the name of services.
It's actually annoying. In aws world, only aws solutions are even mentioned. I notified only after certification that there are many valid use cases for not using Ami's for example. Aws pretty much recommends making a new ami for every little change you make on servers, and if you have a fleet of hundreds of servers and want to change a small config on them, that means building and replacing hundreds of Ami's.
Compare that to ansible that can quickly and in parallell make the change everywhere in seconds.
The immutable infrastructure thing sounds really good in theory but has flaws in practice. The benefits are there but at a big time/money/complexity cost.
