DevOps Lifecycle: Different Phases Explained with Examples
What is DevOps Lifecycle?
The DevOps Lifecycle is a series of development stages that guide everyone as efficiently as possible through the end-to-end process of product development. All of these components of the DevOps lifecycle is necessary to take the maximum leverage of the DevOps methodology.
DevOps Lifecycle: Key Components
Here are some important DevOps Lifecycle phases / Key components of DevOps:
Stage 1) Continuous Development:
This practice spans the planning and coding phases of the DevOps lifecycle. Version-control mechanisms might be involved.
Stage 2) Continuous Integration:
This software engineering practice develops software by frequently integrating its components. It helps to ensure that changes in the source code do not break the build or cause other problems.
Stage 3) Continuous Testing:
This DevOps lifecycle stage incorporates automated, prescheduled, continued code tests as application code is written or updated. Such tests can be written manually or in conjunction with continuous integration tools.
Stage 4) Continuous Deployment:
The deployment process takes place continuously in this DevOps lifecycle phase. It is performed so that any changes made in the code should not affect the functioning of a high traffic website.
Stage 5) Continuous Monitoring:
During this phase, developers collect data, monitor each function, and spot errors like low memory or server connection are broken. For example, when users log in, they should access their account, and a failure to do so means there’s a problem with your application.
Stage 6) Continuous Feedback:
Continuous feedback is like a progress report. In this DevOps stage, the software automatically sends out information about performance and issues experienced by the end-user. It’s also an opportunity for customers to share their experiences and provide feedback.
Stage 7) Continuous Operations:
It is the last, shortest, and most straightforward phase of DevOps. It also involves automating the application’s release and all these updates that help you keep cycles short and give developers and provide more time to focus on developing.
Benefits of the DevOps lifecycle
Here are some essential benefits of the DevOps lifecycle:
- The DevOps lifecycle is a useful approach that guides developers and IT operations professionals through the complex process of app creation.
- Better efficiencies indeed lead to a higher return on investment.
- Widely used by large and small teams can use it to help them organize, align, and track phases in the life cycle.
- Automatic monitoring, testing, and releases help developers detect and fix bugs early.
- Multiple automated methods for collecting feedback mean DevOps developers can learn more about their products and improve the quality of their code.
Which phase(s) of software products are the focus of DevOps?
There are three phases of software products that are the focus of DevOps:
- The Development Phase: In this phase, developers create the code for the application. They work with operators to test and Deploy the application to a staging or production environment.
- The Deployment Phase: In this phase, operators deploy the application to a production environment. They may also perform maintenance tasks on the application.
- The Operations Phase: In this phase, operators monitor and manage the application in production.
