Phase 4: DevOps fundamentals
How does this phase apply to Cloud?
DevOps is all about getting your solutions to run efficiently from development to updates. It's not specific to Cloud, as you can implement DevOps practices on-prem and in hybrid environments as well. DevOps practices are often handled by many roles and some companies have dedicated DevOps Engineers. If your aim is to become a DevOps engineer, this phase will get you started but you'll have to go deeper on your own.
DevOps is a culture, and not a specific tool or service. Read up on what DevOps is. Each cloud platform has a suite of DevOps tools, I've linked a few articles here:
I also think it's worth reading The Phoenix Project it's a pretty fun read because it's a fictional story but it explains the importance of DevOps. But if you'd prefer something more like a textbook with similar ideas, check out The DevOps Handbook.
You should've completed the Cloud Resume Challenge in the previous phase. That project introduces you to DevOps concepts, if you haven't, go back and do so.
