👉 How to implement CI/CD pipeline with AWS CodePipeline

👉 Did you know that 74% of organizations have already adopted DevOps or plan to do so? (Source: Forrester) If you're part of that majority, you'll understand the importance of CI/CD pipelines in streamlining software delivery. In this guide, we'll dive into AWS CodePipeline, walking you through its implementation step by step. Whether you're just starting or seeking optimization, this comprehensive tutorial caters to all levels, ensuring smooth deployments for your projects.

What is AWS CodePipeline?

AWS CodePipeline is a fully managed continuous integration and continuous delivery service provided by Amazon Web Services. It automates the build, test, and deploy phases of your release process every time there is a code change, based on the release model you define.

Components of AWS CodePipeline:

Source Stage: This is where your source code resides, such as AWS CodeCommit, GitHub, or Amazon S3.
Build Stage: In this phase, your code is built using tools like AWS CodeBuild, Jenkins, or third-party build providers.
Test Stage: Here, automated tests are executed to ensure the code meets quality standards.
Deploy Stage: Finally, the code is deployed to the designated environment using services like AWS CodeDeploy.

How the System Works:

AWS CodePipeline orchestrates the workflow of your CI/CD pipeline. When a code change is detected in the source repository, CodePipeline triggers the defined actions in each stage sequentially. For instance, it fetches the latest code from the source, builds it, runs tests, and deploys it based on the configurations you've set. This automation ensures rapid and consistent software releases.

Understanding the Important Keywords and Terminologies:

👉 Continuous Integration (CI): The practice of frequently integrating code changes into a shared repository, verified by automated builds and tests.

👉 Continuous Delivery (CD): Extends CI by automatically deploying all code changes to a staging or production environment after the build stage.

👉 AWS CodeCommit: A fully managed source control service that hosts secure Git repositories.

👉 AWS CodeBuild: A fully managed build service that compiles source code, runs tests, and produces deployable artifacts.

👉 AWS CodeDeploy: Automates code deployments to any instance, including Amazon EC2 instances and on-premises servers.

👉 GitHub: A widely used web-based Git repository hosting service for version control and collaboration.

👉 Amazon S3: Amazon Simple Storage Service, offering object storage with a simple web interface to store and retrieve any amount of data.

👉 Jenkins: An open-source automation server widely used for building, testing, and deploying software.

👉 Pipeline: A set of automated actions orchestrated to deliver software changes from code to production.

👉 Stage: A logical portion of a pipeline representing a phase in the software release process, such as source, build, test, or deploy.

👉 Workflow: The sequence of stages and actions that define the CI/CD process for a particular application or project.

👉 Artifact: Any output produced by the build process, such as compiled code, executables, or deployment packages.

👉 Environment: A target platform where the application is deployed and tested, such as development, staging, or production.
