Environments in the Software Development Life Cycle (SDLC) refer to different stages in the development process where software is tested, deployed, and managed. Typically, there are several environments in an SDLC, including: Development environment: Where software is developed and tested by developers . Test environment: Where software is tested by QA teams to identify and fix bugs and other issues. Staging/UAT environment: A replica of the production environment where software is tested for performance, scalability, and compatibility before deployment to production. Production/PROD/LIVE environment: The live environment where software is deployed and made available to end-users. Each environment has specific requirements, configurations, and security measures to ensure that software functions correctly and that sensitive data is protected.
