# Continuous Delivery

* CD is an approach of automating the steps of delivering code to production. From the time when a developer commits a change to when that change is deployed to production, any step that can be automated, should be -ie testing, change control, the process of deployment, etc.
* Aim
  * is to reduce the time and effort required to deploy code.
  * improves the repeatability and auditability of your deployment process.
    * A repeatable process is inherently less risky, which can encourage organizations to release more often and with smaller changesets
    * Automating deployments greatly improves transparency, which naturally improves auditability
      * Automated deployments can also generate reports that can also help with auditing.
      * Scripts can be stored in version control, allowing for easy review

## A whole ethos

* CD generally encompases
  * CI
  * Trunk based development
  * pipelines
  * Developer led testing ie tdd
