Traditional IT had two separate teams in any organization – the development team and the operations team. The development team works on the software, developing and releasing it after ensuring that the code works perfectly. The Operations team works on deployment, load balancing, and release management to make SaaS live.
They check the application performance and report back any issues, if existent to the development team. These cycles went too long for companies and stimulated a need to build a team of mixed expertise of development, QA, and Operations, introducing the phenomenon of DevOps. DevOps bridges the gap between two teams and helps them operate and evolve applications quickly and reliably.
