DevOps Tutorial- What Is DevOps?

In order to automate the delivery of software and infrastructure updates, DevOps follows modern culture and a set of practices that places a strong emphasis on communication and collaboration between IT operations and development teams. Teams can produce and distribute software more effectively and with higher quality thanks to DevOps. Professionals are in charge of streamlining delivery, automating procedures, and assuring the dependability and stability of production settings.

DevOps is also a set of procedures that unites teams working on development (Dev) and operations (Ops) to automate and speed up the software delivery process. By encouraging cooperation, communication, and integration, Development & Operations seeks to close the gap between development and operations. Continuous integration (CI), continuous delivery (CD), infrastructure as code (IaC), monitoring, and logging are all examples of DevOps practices.
