Essential Guide
A look inside the DevOps movement
DevOps culture demands fast developments and agility in the face of change. The right IT team and tools keep releases flowing at a rapid pace.
Introduction
The DevOps movement has steadily gained traction among IT professionals. DevOps engineers looking for work don't have to look too hard; a quick scan on one job site turned up more than 300 listings. But what does a DevOps job entail? Does a "DevOps engineer" even exist?
People fluent in the DevOps work methodology have skills in both application development and systems operations to help push releases quickly. DevOps is also a philosophy to bridge communication gaps between groups. This guide details the varied aspects of the DevOps movement, how to adopt it and the tools available to facilitate it.
