Understanding The DevOps Lifecycle: Continuous Integration, Delivery, and Deployment
DevOps is a continuous process that involves collaboration, automation, and measurement at every stage of the software development and delivery lifecycle. To understand DevOps, it’s essential to understand the three key stages of the DevOps lifecycle: continuous integration, delivery, and deployment.
Continuous Integration
Continuous integration is the process of automatically building and testing code changes as soon as they are committed to a shared repository. By doing so, teams can quickly identify and fix issues, ensuring that code is always in a releasable state. Continuous integration requires a high degree of automation, including automated testing, building, and deployment.
Continuous Delivery
Continuous delivery builds on continuous integration by automating the process of delivering code changes to production. By doing so, teams can ensure that code changes are always in a releasable state and can be deployed to production quickly and with minimal risk. Continuous delivery requires a high degree of automation, including automated testing, building, and deployment, as well as configuration management and monitoring.
Continuous Deployment
Continuous deployment is the highest level of automation in the DevOps lifecycle. In continuous deployment, every code change that passes automated tests is automatically deployed to production. This requires a high degree of confidence in the automated testing and deployment process, as well as robust monitoring and rollback procedures.
