What exactly is a DevOps Engineer?

Let’s break it down… A DevOps engineer is an IT professional who understands software development (Dev) and is skilled at solving information technology issues by utilizing engineering software and other tools to get around those problems. They also manage the operations (Ops) part of the job. Most of all a DevOps engineer needs to grasp all concepts of their industry and break down the needs of the company to make sure all parts move harmoniously together.  They want things to be faster, more efficient and troubleshoot problems before they occur.  Now that we’ve gotten that out of the way, let’s move onto the good stuff.
