This is an exemplary method of a customer project, based on specific project requirements.
In software development, the staging process is a crucial step to ensure that changes to an application are smoothly transitioned into the production environment without undesired impacts. The goal of the staging process is to test, validate, and observe any installations and changes before their go-live. The process is applied to all releases and patches and encompasses a total of 28 working days until deployment to the production environment (go-live). The order of the stages must always be followed as each environment serves a specific purpose.
The following are brief explanations of the different environments used in the staging process: DEV, TEST, LAST, INT, prePROD, and PROD. It will elucidate the specific purposes and benefits of each environment and how they work together to ensure software quality and reliability.
The PROD environment is extremely important as it reflects the real-world usage of the application. Performance, reliability, and security must be ensured here. As the PROD environment is critical to production, changes and updates are carefully monitored and managed to minimize downtime and disruptions. Regular maintenance is typically performed in the PROD environment to maintain application performance and security.
The staging process aims to minimize the risks and impacts of changes to an application before transitioning them to the PROD environment. Each environment plays a crucial role in verifying the quality and stability of the software. By progressing step by step through the different environments, errors can be detected and resolved early, ultimately leading to an improved user experience and higher customer satisfaction.
