Deployment

Deployment is like launching a ship into the water after it’s been built and tested in the dockyard.

Releasing a new version of a mobile app to the App Store, or launching a website on a live server.

Deployment is the final step in delivering a product to users, and it must be done carefully to ensure the software works as expected in the live environment.

Successful deployments lead to positive user experiences, while problematic deployments can result in downtime, user frustration, and lost revenue.

• Use Case 1: Releasing new features or updates to a web application.
• Use Case 2: Deploying emergency bug fixes to resolve critical issues in production.
• Use Case 3: Scaling an application to handle increased traffic by deploying it across multiple servers.

‍

Automate deployments using CI/CD tools; test thoroughly in staging environments; monitor the deployment closely for issues.

Inadequate testing leading to failures in production; manual deployment processes that introduce errors; poor rollback strategies in case of failure.
