Correct answer - "Re-design the pipeline to include steps to occur in parallel where possible" :
Actions in parallel in CodePipeline can help with speed requirements.
Incorrect:
"Upgrade the AWS CodePipeline instance type" - There is no instance types. A pipeline is a
workflow construct that describes how software changes go through a release process. You define
the workflow with a sequence of stages and actions.
"Ask for a 'speed boost' from the AWS support" - You can but they may redirect you to
documentation to re-design your pipeline
"Enable pipeline caching" - There is no caching instead pipeline is a workflow that describes the
stages and actions
