  2. Continuous Delivery
    • the code is automatically built, tested and deployed to production, or at least to a staging environment if not production.
    • Tools: Jenkins, Travis CI, CircleCI, GitLab CI
  3. Continuous Deployment
    • the code is automatically built, tested and deployed to production.
    • Tools: Jenkins, Travis CI, CircleCI, GitLab CI
  4. Infrastructure as Code
    • you define your infrastructure in code, which can be version controlled and tested.
    • Tools: Terraform, CloudFormation, Ansible, Chef, Puppet
  5. Monitoring and Logging
