A canary deployment gradually routes a small percentage of traffic to the new version to detect issues before rolling out to all users.
In a CI/CD pipeline, what does 'shift-left testing' mean?

Shift-left testing means incorporating testing earlier in the software development lifecycle to find and fix defects sooner and at lower cost.
What is the role of a 'build server' in a CI pipeline?
Answer: To compile source code, run tests, and produce deployable artifacts automatically
A build server automates the process of compiling code, running tests, and packaging artifacts whenever changes are pushed to the repository.
What is 'pipeline as code'?
Answer: Defining CI/CD pipeline configuration in version-controlled files
Pipeline as code means storing pipeline definitions in version-controlled files (like Jenkinsfile or .gitlab-ci.yml) so they are treated like application code.
