AWS CodePipeline
What is it?
AWS CodePipeline is a managed service that automates your release process as a series of stages — building, testing, and deploying code automatically.
Explain like I'm 5
Why was it created?
Manually coordinating build, test, and deploy steps is slow and error-prone. CodePipeline was created to automate that flow on AWS.
Where is it used?
- Automating releases
- Orchestrating CI/CD stages
- Connecting build and deploy tools
- AWS-native delivery pipelines
Why should developers care?
CodePipeline is the orchestration layer of AWS-native CI/CD, tying build and deploy steps together for cloud teams.
How does it work?
You define stages (e.g. source, build, test, deploy), each with actions that call services like CodeBuild or deployment tools. When code changes, the pipeline runs the stages in order, advancing automatically (or after manual approval) toward release.
Real-world example
A push to the main branch triggers CodePipeline: it pulls source, runs CodeBuild to test and package, then deploys to staging and (after approval) production.
Common use cases
- End-to-end release automation
- Orchestrating CI/CD stages
- Manual approval gates
- Coordinating AWS deploy tools
Advantages
- Automates the full release flow
- Integrates AWS build/deploy tools
- Supports approval gates
- Managed and scalable
Disadvantages
- AWS-specific
- Setup complexity
- Less flexible than some CI tools
- Best within the AWS ecosystem
When should you use it?
When you want to automate and orchestrate releases end to end on AWS.
When should you avoid it?
When a single tool like GitHub Actions already orchestrates your whole pipeline.

Common misconceptions
- "CodePipeline builds the code itself" — it orchestrates stages and calls build services like CodeBuild to do the work.
- "Pipelines must be fully automatic" — you can insert manual approval gates before sensitive stages.
Fun facts
- CodePipeline orchestrates other services; CodeBuild typically does the building.
- Manual approval actions let a human gate a release before production.
