Deployment refers to the process of making a software application available for use. This can involve various stages, including planning, testing, and releasing the software to users. Effective deployment ensures that the application runs smoothly and meets user expectations, often utilizing tools and practices like CI/CD (Continuous Integration/Continuous Deployment) to automate the process. In modern software development, deployment is crucial for delivering updates and new features quickly. It can be done in various environments, such as cloud or on-premises servers. Proper deployment strategies help minimize downtime and improve user experience, making it a vital aspect of software lifecycle management.
