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
