DevOps is Software technological course used for the software development (dev) and operations (ops). It is an Automation technology which helps to reduce the manpower and monitor to develop the software construction from integration, testing and releasing to deploy. This automation technology aims development cycles in a shorter way, deployment frequency increasing and maintaining alignment with business targets.
