Terminology
• Continuous integration (CI) automatically builds, tests, and integrates code changes within a shared repository; then
• Continuous delivery (CD) automatically delivers code changes to production-ready environments for approval; or
• Continuous deployment (CD) automatically deploys code changes to customers directly.

Why CI/CD?
• Development velocity
– Ongoing feedback allows developers to commit smaller changes more often, versus waiting for one release.
• Stability and reliability
– Automated, continuous testing ensures that codebases remain stable and release-ready at any time.
• Business growth
– Freed up from manual tasks, organizations can focus
resources on innovation, customer satisfaction, and
paying down technical debt.

What makes CI/CD successful
• Automation
– A good CI/CD workflow automates builds, testing, and deployment so you have more time for code.
• Transparency
– Quickly assess what went wrong and why.
• Speed/Resilience
– Lead time for changes (how quickly commits are made to code in production); Time to resolution (how quickly incidents are resolved); etc.
• Security
– Virtual paper trail for auditing failures, security breaches,
non-compliance events.

GitHub Actions
• GitHub Actions gives developers the ability to automate their workflows across issues, pull requests, and more—plus native CI/CD functionality.
• Launched in 2018.

GitHub Actions
• Brings automation into the software development lifecycle on GitHub via event-driven triggers.
• Triggers are specified events that can range from creating a pull request to building a new brand in a repository.
• GitHub Actions automations are handled via workflows, which are YAML files.

GitHub Actions Workflows
• Events: Events are defined triggers that kick off a workflow.
• Jobs: Jobs are a set of steps that execute on the same runner.
• Steps: Steps are individual tasks that run commands in a job.
• Actions: An action is a command that’s executed on a runner.
• Runners: A runner is a GitHub Actions server.
