Benefits Of Devops

The biggest shift in attitude in a DevOps environment is that there is one team composed of cross-functional team members including developers, QA, DBAs, business analysts, operations engineers and so forth. Collaboration across these different roles delivers many benefits.

Technical benefits:

  • Continuous software delivery
  • Less complex problems to fix
  • Faster resolution of problems

Business benefits:

  • Faster delivery of features
  • More stable operating environments
  • More time available to add value (rather than fix/maintain)
