The 3-phase approach to deployment is a common method for releasing software to production efficiently and with control. It comprises:
1. Development Phase: In this stage, the software is created and tested in a non-production setting to ensure it functions correctly and to address any defects before moving to production.
2. Staging Phase: This phase replicates the production environment, allowing for software deployment and testing before user release. It helps in identifying and resolving potential issues before they affect users.
3.Production Phase: This is where users interact with and access the software, as it becomes available for their use.
