Deployment is the process of releasing software applications, updates, or features to a production environment where end users can access and use them. It involves moving code from development or testing stages to live servers.
In software development and DevOps, deployment ensures that applications run reliably in real-world environments. It includes configuration, server setup, database integration, and monitoring to maintain performance after release.
For example:
- A web application is deployed to a cloud server so users can access it online.
- A mobile app update is released to the Google Play Store or Apple App Store.
- A new feature is deployed after testing in a staging environment.
- An e-commerce platform updates its checkout system without downtime.
Common technologies and concepts related to deployment include:
- CI/CD (Continuous Integration / Continuous Deployment)
- Cloud Platforms (AWS, Azure, Google Cloud)
- Docker
- Kubernetes
- Hosting Servers
- Version Control (Git, GitHub)
- Staging Environment
- Production Environment
- DevOps Practices
