What is DevOps?

1 Mins read

DevOps is a bridge between development and operations. It is a set of tools, applications, and approaches designed to help organizations software and application release cycles to improve their scalability, quality, and security. This approach covers the process from the development environment to the production environment. DevOps brings development and operations teams together to eliminate waste of time, communication problems, and negatives that will prevent the development process from progressing.

Advantages of DevOps

  • The software goes live faster and smoother.
  • “Continuous Improvement” can be applied more frequently and easily.
  • Faster delivery of product features.
  • More stable systems.
  • Gaining more time for improvement rather than troubleshooting.
  • Faster solutions to problems.
  • Trust and cooperation get stronger between teams.

Continuous Integration

Continuous Integration (CI) is the process of where the builds and test stages are run automatically in every change in the code on the Version Control Systems. Every time a developer pushes changes in the Version Control System, the code is compiled first and then the relevant tests are run. If there is an error, it will be reported to the developer instantly.

Continuous Delivery

In this stage, the project built in the Continuous Integration stage, going to be deployed on the specified environments (Test, Preprod, Production, etc.). The important thing is the deployment needs to be done by clicking one button to continue the process. All the processes work automatically until the deployment phase. But someone needs to trigger the deployment process manually. This stage is an extension of Continuous Integration.

Continuous Deployment

This stage is very similar to Continuous Delivery but there is an important difference between them. The difference comes out when the process reaches to deployment step. In Continuous Delivery, we have triggered the deployment manually but in Continuous Deployment, this should be done automatically. So, the process starts with Continuous Integration and finished on the Continuous Deployment stage without any manual interaction. Generally, this stage deploys the products to the Production environment. Every time new changes pushed to the Version Control System, all the changes will be deployed to the Production environment automatically.
