In DevOps, the organization responds in a more agile manner to changing business requirements. In this concept, systems engineers, release engineers, DBAs, network engineers, and security professionals in the “Ops” branch seamlessly integrate with developers, QA, business analysts, and product engineers in the “Dev” branch into a single value IT entity.
There are four basic continuous processes in DevOps:
- Continuous Integration
- Continuous Delivery
- Continuous Testing
- Continuous Monitoring
In DevOps, testing is not at the end of the release cycle — it is now brought into the mainstream/beginning of development cycles. Developers and system engineers get the code in the right environment for Continuous Integration and Continuous Delivery and those stakeholders enable Continuous Testing and Continuous Monitoring processes in which QA engineers then validates that the team has built the right application, by seeing and testing if it functions and performs as designed.
DevOps is not a methodology or a suite of tools but it is a concept to dismiss the barriers between Dev and Ops in order to meet the need for shorter and more frequent delivery timelines.
Agile and DevOps
Organizations have embraced Agile as a response to rapidly changing requirements and DevOps as a response to the demand for speed.
DevOps involves practices, rules, processes, and tools that help to integrate development and operation activities to reduce the time from development to operations. DevOps has become a widely accepted solution for organizations which are looking at ways to shorten the software lifecycles from development to delivery and operation.
The adoption of both Agile and DevOps helps the teams to develop and deliver quality software faster, which in turn is also known as “Quality of Speed”. This adoption has gained much interest over the past five years and continues to intensify in the coming years too.
