Infrastructure as Code (IaC) is a practice that allows you to define and manage your infrastructure using code. This means you can version, test, and deploy your infrastructure just like application code. In CI/CD, IaC fits in by enabling automated provisioning and management of infrastructure within the continuous integration and continuous deployment pipelines, ensuring consistency and reducing manual errors. Tools like Terraform and CloudFormation are commonly used for this purpose.

Canary deployment is a strategy where a new version of software is released to a small group of users first, allowing for monitoring and testing before it is rolled out to the entire user base.

Containers in CI/CD package applications consistently, ensuring that they run the same way in different environments. CI/CD pipelines can build, test, and deploy these container images to platforms like Kubernetes, streamlining the development and deployment process.

The typical stages of a CI/CD pipeline are:

1. Code commit
2. Build
3. Unit Test
4. Integration Test
5. Deploy to staging
6. Manual approval (optional)
7. Deploy to production
8. Monitor

Version control is a system that records changes to code over time, allowing multiple developers to collaborate effectively. It relates to CI/CD by enabling continuous integration and continuous deployment processes, where CI/CD tools monitor version control repositories (like Git) and automatically trigger build and deployment pipelines based on code changes, such as commits or pull requests.
