DevOps aims to improve collaboration, and it certainly can do that. But software deployment grinds to a halt if teams don't establish a strategy and adopt tools to deploy patches without disrupting workflows or application stability. Ideally, DevOps tools and methodologies should substantially reduce the time to fix, which is an all-important software metric. Practitioners can run into obstacles, however, when trying to integrate legacy patching processes with new workflows and systems that change both development and IT processes and tools. The foundation of DevOps process agility is automation of the entire software development pipeline from code building and review to testing and deployment. The techniques of continuous integration and deployment (CI/CD) and the need for automation tools to streamline the process are universally accepted concepts. Even so, the application of these techniques, as well as the selection of automation tools, is inconsistent. Many times, IT and development organizations are forced to cobble ...

Features in this issue
Enterprise data center teams can learn important lessons from hyperscale cloud providers. Rethink redundancy strategies and consider technologies like SDN to increase efficiency.
Enterprises engaged in a CI/CD workflow must patch systems and apps strategically. There are multiple technologies to consider, including immutable infrastructure and automation.
To reap the benefits, a cloud migration requires a well-thought-out IT strategy. But some enterprises continue to make the move too soon -- and then pay a price.
Columns in this issue
It's easy to chase -- or hide from -- IT automation trends, without truly understanding what automation projects will benefit the data center and business the most.
Emerging technologies such as containers, HCI and big data have blurred the lines between compute and storage platforms, breaking down traditional IT silos.
