Devops Training Course

DevOps Training CourseSDLC -Progress

DevOps is a term for a group of concepts that, while not all new, have catalyzed into a movement and are rapidly spreading throughout the technical community. Like any new and popular term, people may have confused and sometimes contradictory impressions of what it is. Here’s my take on how DevOps can be usefully defined; I propose this definition as a standard framework to more clearly discuss the various areas DevOps covers. Like “Quality” or “Agile”, DevOps is a large enough concept that it requires some nuance to fully understand.

It’s a misconception that DevOps is coming from the development side of the house to wipe out operations – DevOps, and its antecedents in agile operations, are being initiated out of operations teams more often than not.

Very often, automation supports this objective. DevOps integration targets product delivery, continuous testing, quality testing, feature development, and maintenance releases in order to improve reliability and security and provide faster development and deployment cycles.

Introduction of DevOps

DevOps was initially called as ‘Agile operations’ or ‘Agile System Administration’. It emerged as a fusion of two major trends. Basically, it is more of a culture which includes practices that bring the development and operations teams in an organization together. Various factors such as application performance, functional requirements and project spend have the ability to become conflicting priorities that disrupt the co-existence of development and operations teams.

DevOps helps to increase the overall standard and to pose a check on the number of interruptions. Attaining maximum efficiency and achieving higher performance is the goal in any business operation and DevOps helps in reaching it. Some other notable advantages that come along while using DevOps are reduced time spans to overcome failure, reduced deployment rollbacks, reduced development cycle, improved defect detection and improved release velocity.

The benefits of DevOps outweigh the technical difficulties faced in merging the two environments.

It delivers system to customers faster and also reduces production changes by automating non-functional testing and shortening development iterations.
It automates service management allowing support for operational goals and improves understanding of the layers of production environment thereby helping prevent or resolve production issues easily.

The potential benefits of DevOps are difficult to measure but can only be seen as decrease in production and operation cost.
