DevOps originated with operations as a means of streamlining and improving the effectiveness of operations in the face of increasing workload. Traditionally operations had the time to deal with application stability, risk, and performance issues on one hand, and infrastructure management and procurement tasks on the other. This changed with the simultaneous adoption of Agile practices in development resulting in increased deployment frequency, while at the other end the trend towards cloud and virtualization speeded up and lowered the costs relating to hardware issues - almost overnight operations became the bottleneck. The availability of new deployment solutions has significantly helped operations by automating many manual operations. The solutions from a range of leading vendors and innovators in release management and automation are compared side by side in the Ovum rainbow map for DevOps. This solution guide and comparison will help IT managers choose a solution that is a good fit for their operations needs.
