Are you doing continuous integration or continuous delivery?

Whilst discussing [de-jargoning Drupal and Drupalisms][0] with Emma Horrell and Luke McCormick, I started thinking about pieces of jargon I come across regularly.
|
||
|
|
|
||
|
|
Common ones are CI and CD.
|
||
|
|
|
||
|
|
CI (or continuous integration) is not about whether you have a CI pipeline and use a tool like Jenkins, GitHub Actions or GitLab CI (despite how some of these tools are named).
|
||
|
|
|
||
|
|
Continuous integration is how often code is integrated together.
|
||
|
|
|
||
|
|
If it's been more than a day since you last merged your code into your mainline branch, you're not doing continuous integration.
|
||
|
|
|
||
|
|
The less often you merge code, the more likely it is there will be conflicts or incompatibilities with other code that's been worked on - whether it's someone else's code, or code that you're writing in a different branch for a different task.
|
||
|
|
|
||
|
|
CD stands for is continuous deployment or continuous delivery.
|
||
|
|
|
||
|
|
When is the last time you deployed changes to production?
|
||
|
|
|
||
|
|
If it's been more than a day, you're not doing continuous deployment.
|
||
|
|
|
||
|
|
I've worked on teams and projects when it's been months between production releases.
|
||
|
|
|
||
|
|
I much prefer releasing small, iterative and continuous improvements to production instead of doing large and risky deployments.
|
||
|
|
|
||
|
|
Developers get their changes released sooner, end users get fixes and new features sooner, and it's easier to identify and resolve issues when releases are smaller and more frequent.
|
||
|
|
|
||
|
|
How about you?

Are you doing CI or CD?

What other Drupal or techy jargon terms do you see regularly?
