Deployment refers to the process of making a software application or system available for use. This involves transferring the application from a development environment, where it is created and tested, to a production environment, where end-users can access it. Deployment can include various steps such as installation, configuration, and testing to ensure everything works correctly. In the context of technology, deployment can also involve updates or patches to existing systems. This ensures that software remains functional and secure over time. Different methods of deployment, such as cloud computing or on-premises installation, can be used depending on the needs of the organization and the nature of the application.
