CI/CD

A process to take a code, package it up and deploy it to a system that can be serverless, a VM, or a container.

CI/CD has 3 steps:

CI – Continuous Integration
CD – Continuous Delivery
CD – Continuous Deployment

Continuous Integration

A process in which the code is merged from multiple contributors and added to a single repository.
Key Processes of Continuous Integration:
- Package up the code
- Test the code (run unit tests, integration tests, etc)
- Run security checks against the code

Continuous Delivery vs Continuous Deployment

In Continuous Delivery, to deploy the code after the CI process you have to manually trigger it via some button to deploy on the system.
In Continuous Deployment, the deployment is automatic.
Key Pieces of Continuous Deployment:
- Ensure you're authenticated to the system or wherever you're deploying
- Ensure that the code that's being deployed is working as expected once it's deployed
