DevOps:
Is it worth the time and money to get AWS/GCP/Azure Certified? Other than adding a line to your resume...

IMHO, no. Certification on those platforms will not really add to the value. I'd invest time and money in the devOps tools certifications you use, puppet, ansible, chef, saltstacl. and alike. Most of these tools have a way to manage all those cloud technology stacks,..

What is valuable though is that you can demonstrate the power of your devOps with example instances of these cloud providers.

I'm going to follow a course o. Puppet, the practitioner course, already have two course completion certifications in my pocket.
