What is Deployment?

In software development and operations, deployment refers to the process of making a software application or update available for use. This involves copying the application code, configurations, and dependencies to a target environment (e.g., a server, a cloud platform, or a user's device). Common deployment strategies include rolling deployments (gradually replacing old versions with new ones), blue-green deployments (running two identical environments, switching traffic to the new one after testing), and canary deployments (releasing the new version to a small subset of users before a full rollout). Effective deployment processes are often automated using tools and techniques like continuous integration/continuous deployment (CI/CD) to ensure reliability, speed, and consistency.
