Introduction to DevOps

DevOps stands for development and operations. It is a tool and technology combined to carry out various business processes. It aims to bridge the gap between two of the most significant departments in any IT organization, namely, the development department and the operations department. DevOps helps to make software production and deployment in an automated & repeatable way. So, doing this increases the organization’s speed to deliver software applications and services.
This technology gives organizations an edge over competitors. It also helps them to serve their customers better. In simple words, DevOps is an alignment of development and IT operations with better communication and collaboration.

Why do we need DevOps?

  • Before this technology, the development and operation team worked in complete isolation.
  • Testing and Deployment were isolated activities done after design-build. Hence, they consumed more time than actual build cycles.
  • In addition, Without using DevOps, team members spent a large amount of their time on testing, deploying, and designing instead of building the project.
  • Manual code deployment leads to human errors in production
  • Lastly, coding & operation teams have separate timelines and are not in sync. Thus, it causes further delays.


DevOps is deep integration between development and operations. Understanding DevOps concepts is impossible without knowing its lifecycle.
Therefore, here is a piece of brief information about the continuous DevOps life-cycle:
1. Development
In this DevOps stage, the development of software constantly takes place. In this phase, the entire development process is separated into small development cycles. Thus, this helps the DevOps team to speed up the software development and delivery process.
2. Testing
QA teams use tools like selenium to identify and fix bugs in the new piece of code.
3. Integration
In this stage, we integrate new functionality with the prevailing code. Then, testing takes place. Continuous development is only possible due to continuous integration and testing.
4. Deployment
In this phase, the deployment process takes place continuously. Therefore, any changes made at any time in the code should not affect the functioning of a high-traffic website.
5. Monitoring
In this phase, the operation team will take care of the inappropriate system behaviour or bugs that appear in production.
