Deployment

The process of making a software application available for use.

Deployment is the process of releasing a software application or update into an environment where it becomes available to users. This includes activities such as building the application, transferring artifacts to servers or cloud platforms, running database migrations, and configuring networking and DNS.

Deployment strategies vary in complexity and risk. Common approaches include rolling deployments (gradually replacing instances), blue-green deployments (switching traffic between two identical environments), and canary deployments (routing a small percentage of traffic to the new version before full rollout). Each strategy offers different trade-offs between speed, safety, and resource usage.

In serverless architectures, deployment is simplified because there are no servers to provision or maintain. Deploying a Cloudflare Worker, for example, involves pushing code and configuration to the platform, which handles distribution to edge nodes globally. API gateway configurations are often deployed alongside application code, with routing rules, security policies, and rate limits treated as part of the deployment artifact.
