DevOps is the combination of development and operations. In this culture and practice of software development, development and IT operations work together. The reason lying at the roots of DevOps concept was the disconnection between these two but DevOps extends far beyond the IT organization in time with the need for interaction between everyone who has a place in the delivery process of any software.
DevOps relies heavily on automation and that is why it needs some specific tools and toolchains to automate large parts of the end – to – end software development and deployment processes. But it would be a mistake to see DevOps only as a collection of tools. It operates on tools but DevOps is a culture and a way of working together harmoniously, meaning it is just more than those tools it relies on.
3. Continuous Integration
The principle of continuous integration of DevOps mindset forces developers to integrate their works with one another more frequently. This exposes possible integration issues and conflicts much earlier in the development process. To achieve this benefit, developers must communicate with each other much more often against the common notion of coders working on their own all the time.
4. Continuous Testing
Though continuous integration and delivery are much more well known, continuous testing is equally important as part of DevOps culture. Testing is not just a QA function it involves each and every member of development process. The test function in a DevOps environment, when it is well-handled, helps developers to balance quality and speed. By using automation tools, you can reduce the cost of testing and reduce test cycles by allowing integration testing earlier in the process.
5. Continuous Delivery
Continuous delivery is kind of a continuation of integration to the next steps including QA and operations. Delivery step has lots of variables like release date or release frequency. What gets released varies as well. Some go directly to the users, some go back to development and the other ones are not deployed at all.
6. Continuous Monitoring
Because of the huge number of releases, in DevOps environment, failures must be found and fixed in real time. The main way of doing this is continuous monitoring. The goals of continuous monitoring are determining when a service is unavailable, understanding the underlying causes and anticipating problems before they occur by using these learnings. It can be said that monitoring starts in development process just like testing.
