What is DevOps?
Development and Operation (DevOps)
Dev – refers to Developers (People involved in developing the product)
Ops – refers to Operations (System Engineers, System Administrators, DBA, Network Engineers, Security professionals etc)
So DevOps is not a title/job/profession, DevOps is a culture. A healthy culture of organization’s Dev and Ops guys to cooperate with each other.
DevOps is a culture, movement or practice that emphasizes the collaboration and communication of both software developers and other information-technology (IT) professionals while automating the process of software delivery and infrastructure changes. It aims at establishing a culture and environment where building, testing, and releasing software can happen rapidly, frequently, and more reliably.
DevOps ensure continuous software delivery with less complex problems to fix and faster resolution of problems.
The developer team is the one who writes code for the application, security and bug fixes. So, once the development is over, the code will be given to the operations team for deployment in the production environment. The developer team has to wait for days for the code to be deployed in the production environment. After deployment, the application might not work the way it worked in the development environment. It happens when the development environment is not identical to the production environment. The operations team will work on the necessary changes to make sure the application is running smoothly. The operations team can also face problems again because of the new code. They might think the problems are caused because of the bugs in the code, while the developer team might think there is some issue with the configurations made by the operations team. This is where Devops comes into play.
A DevOps team thus automates everything from infrastructure provisioning to code testing and deployments.
DevOps tools can be categorized based on the layer of Automation. Check the link given below to know more about different DevOps tools.
