Project deployment refers to the process of making a software application available for use in a production environment. This involves packaging the application, configuring the necessary infrastructure, and ensuring that it runs smoothly for end-users. Deployment is crucial as it transitions the application from development to a live setting, where it can be accessed and utilized. Various strategies exist for deployment, including methods like Blue/Green and Canary deployments, each with its own advantages and challenges. Understanding deployment is essential for developers to ensure that their applications perform reliably and efficiently in real-world scenarios.
