Application Environment

Development Environment

QA Environment

Production Environment


---

When deploying an application, there are typically several distinct environments used throughout the development and release process. These environments serve different purposes and ensure that the application is thoroughly tested and stable before being released to end users. The number of environments can vary depending on the complexity and requirements of the project, but the most common ones include:

1. Development Environment (DEV)

2. Integration Environment

3. Testing Environment (TEST)

4. Staging Environment (STAGE)

5. Production Environment (PROD)

6. Disaster Recovery Environment (DR)

7. Performance Testing Environment

8. Sandbox Environment

Summary

While the above environments are common, not every project will use all of them. Smaller projects might combine some environments (e.g., integrating testing and staging), while larger, more complex projects might have additional specialized environments. The key is to have a well-defined process that ensures code is thoroughly tested and stable before reaching the production environment.
