But before you start cooking up deployments, let's make sure we're on the same page about CI and CD:

CI vs. CD: What's the difference?

Think of CI (Continuous Integration) as the preparation stage. Every code change gets automatically merged into a central repository, triggering a series of tests to ensure everything is working smoothly. It's like checking all your ingredients and prepping them before you start cooking.

CD (Continuous Deployment) takes things a step further. If all the tests pass in CI, your changes are automatically deployed to production. It's like putting your prepped ingredients straight into the oven and letting the magic happen!

Is Continuous Deployment right for my business?

While CD has numerous benefits like faster release times and improved software quality, it's not a one-size-fits-all solution. Here's a quick checklist to see if CD might be a good fit:

• Do you have a well-established CI pipeline? CD relies heavily on a stable and reliable CI process.
• Are your releases frequent and small? CD works best with small, incremental changes rather than large, risky updates.
• Do you have a robust monitoring and rollback strategy? Even with automated tests, things can go wrong. You need a plan for identifying and fixing issues quickly.

Rolling back: When things don't go according to plan

Let's face it, even the best-laid plans can go awry. In case your deployment takes a wrong turn, having a rollback strategy is crucial. Here's how it works:

• Identify the problematic deployment version.
• Quickly switch back to a previous, stable version.
• Analyze the issue and fix the bugs in the faulty deployment.

Remember: Rollback should be fast, reliable, and well-tested to minimize downtime and impact on users.

Food for thought: Is CD worth it?

According to a 2023 survey by CircleCI, organizations that use CD experience:
