DevOps is a new and popular term that has slowly catalysed into a movement and is spreading like a wildfire in the technical community. Like any other new term in the technical community, people have developed contradictory illusions on what the term means. DevOps is a term describing the collision of two major and closely related fields.
The first field is the agile system administration that arose from applying agile and lean approaches to operations. The second field is an augmented understanding of the value gained from collaborating between development and operations staff in all stages of the development lifecycle of creating a service. Operations have also become quite important in our increasingly service-oriented world.
Challenges solved by Developer Operations
Developer Operations is essential because of the problem it solves, prior to Developer Operations application development, developer teams were in charge of gathering business requirements for software programs and then writing code. A QA team would then test the written code in an isolated environment, and if the code met the requirements set at the beginning, the team would release the code for operations. The problem of this paradigm is that teams would work separately.
Benefits of DevOps
The CHEF development kit provides tools to develop and test infrastructure automation code locally from a workstation. The Test Kitchen tool allows testing code before deployment into the business environment, and the testing is done in an isolated environment. The server acts as a central repository about every node that the server manages. Cookbooks have code describing the desired state of an infrastructure.
A client is a node, either virtual or physical in a network that is managed by the system Server. The client runs on every node initiating secure communication with the server to get configuration instructions. The client uses the instructions received to bring a node to the desired state.
Benefits of using this system
The underlying technology in this platform has been beneficial in accelerating cloud adoption and in the management of diverse environments for both data and cloud environments. Finally, the system can be used to maintain a high availability in cases of partial network and hardware failures.
