π AWS CodePipeline:
A fully managed service to automate the build, test, and deployment phases of your release process.
Detailed Explanation
AWS CodePipeline is a service provided by Amazon Web Services that streamlines the process of releasing software. It allows developers to set up automated workflows where their code can be built, tested, and deployed automatically without requiring manual intervention at each step. This automation helps in speeding up the development process and ensures that any new code or changes are deployed consistently and reliably.
Examples & Analogies
Think of AWS CodePipeline as an assembly line in a factory. Just as an assembly line takes raw materials and sequentially processes them into a finished product, CodePipeline takes code changes and progresses them through different phases (build, test, deploy) until they are released into production.
Pipeline Stages

πΉ Pipeline Stages:
β Source: Connects to code repo (GitHub, CodeCommit).
β Build: Triggers CodeBuild or 3rd party service to compile/test.
β Deploy: Uses CodeDeploy or Elastic Beanstalk.
Detailed Explanation
A CodePipeline consists of various stages that each play a crucial role in the software release process:
1. Source: This is where the pipeline begins. It connects to a source code repository, such as GitHub or AWS CodeCommit, to pull the latest version of the code whenever changes are detected.
2. Build: In this stage, the code is compiled and tested using AWS CodeBuild or other third-party services. This ensures that the new code integrates well with existing code and passes predefined tests to catch any errors early.
3. Deploy: Finally, the code is deployed using AWS CodeDeploy or AWS Elastic Beanstalk, which pushes the code to the production environment where users can access it.
Examples & Analogies
Imagine you're baking a cake. You start at the source stage by gathering all the ingredients (Source), then mixing and baking them (Build), and finally decorating the cake and serving it to guests (Deploy). Each step is necessary to ensure that the final product is delicious and well-prepared.

πΉ Deployment Types:
β In-place deployment: Updates running instances.
β Blue/Green deployment: Switches traffic between environments.
Detailed Explanation
AWS CodeDeploy supports two main types of deployment strategies:
- In-place deployment means that the existing instances are updated with the new code. This is straightforward but might involve downtime if the deployment is not carefully managed.
- Blue/Green deployment is a more sophisticated strategy where two identical environments (Blue and Green) are maintained. The idea is to deploy the new version of the application to the Green environment while the Blue environment is live. Once the new version is confirmed to be stable, traffic is switched from Blue to Green, minimizing downtime and risk.
Examples & Analogies
Consider a restaurant that wants to introduce a new dish. An in-place deployment is like changing the menu of the existing restaurant, which might require temporarily closing for re-training of staff. Blue/Green is like opening a new location serving the new dish while keeping the old restaurant running. Once the new location is confirmed to be popular, they can seamlessly shift customers there.
