The term “DevOps” was popularized in 2009 in Belgium. DevOps is an abbreviation for Development and Operations. It is not a technology or a product but it is a combination of culture, people, process, and technology. We can think of it as a combination of application development and systems operations activities. Better to consider it with addition of automation that can transform and improve IT delivery with highest quality of end product.
It is based on lean and agile principles. This approach takes a new or enhanced business capability from an idea to all the way to production; providing business to customers in an efficient manner and taking feedback as customers engages with the capability. It emphasizes on collaboration, communication, and integration between application developers and operations staff. In simple English, we can say DevOps is a blending of tasks of Development and Operation teams to make application delivery more effective and faster.
Nowadays, enterprise applications are so diverse and composed of so many technologies, end-user devices, open source and commercial products that DevOps approach can be a boon for organizations while dealing with these complexities. In DevOps culture, business owners, development teams, operations teams, and QA teams collaborate to deliver outcome in a continuous and effective manner. It enables the organizations to more quickly grab opportunities and reduce the time to include customer feedback into new feature development or innovation. The end goal of DevOps is to reduce the time between the initial concept and the end result of the concept in the form of production ready application. DevOps aims to help such organization to rapidly produce or modify applications and services offerings.
Benefits of DevOps
- Provides stable operating environments – Less problems to fix, considering similar deployment environment
- Effective release management allows better control of outsourced or distributed development effort.
- Provides faster development and delivery cycles, increasing response to customers enhancing customer experience and loyalty
- Provides continuous delivery of applications hence provides faster solution of problems
DevOps targets application delivery, new feature development, bug fixing, testing, and maintenance releases. It improves efficiency, security, reliability, predictability, and faster development and deployment cycles. It supports in effective application release management process by regulating development and deployment environments.
DevOps on Cloud is a combination of agile practices and processes leveraging the benefits of cloud resources. Agile development and testing methodology help us to meet the goals of continuous integration, development, build, deployment, test, and release phases. It provides mechanism for constant feedback from different teams and stakeholders. Every important change to an application’s configuration or source code is stored in a version control system such as GIT or SVN. It triggers the creation of a new cycle of the pipeline with a new build. Every time a change is made to the source code, the resulting executable file, WAR or EAR file is build and tested. The practice of building and testing your application on every check-in is known as continuous integration. Continuous delivery depends on continuous integration — and continuous integration depends on automation.
