In the modern cloud-based era, serverless architectures are revolutionizing the way we build and deploy applications. Those days are gone when it was complex to manage and build servers, worrying about the server capacity as well as paying for the idle infrastructure. In the year 2025, AWS offers a complete set of serverless tools that enable development teams to create fully automated CI/CD pipelines without managing a single server.
With this guide, you will come to know how to build a production-ready, serverless CI/CD pipeline that automatically builds, tests, and deploys your applications whenever code changes are pushed. For learning this in detail, one can apply for the AWS DevOps Online Course, where they can get the complete knowledge for the same.
Why Choose a Serverless CI/CD pipeline?
Before you implement this, it is important to understand why the serverless CI/CD has become the preferred approach for modern development teams. Many of the traditional CI/CD solutions need provisioning and maintaining the dedicated build servers, scaling infrastructure based on demand, and managing security patches and updates. If you are using the Serverless CI/ CD, then you will be able to eliminate these operational burdens in an easier way.
The Serverless approach offers great benefits, but to take this, one may need to take AWS DevOps Online Training. Its benefits include paying only when your pipeline runs, reducing the costs for the idle infrastructure. There would not be server management overhead as AWS will be able to handle all infrastructure concerns.
Core Components of a Serverless CI/CD Pipeline
A serverless CI/CD pipeline on AWS uses several services to automate the process of building, testing, and deploying applications. If you are looking to learn about these, then taking the AWS DevOps Certification Coursewill help you understand them.
1. AWS CodePipeline: The Workflow Manager:
It is a powerful tool that can help manage the entire process. This automatically moves your code through the different stages, such a building, testing as well and deploying. It can help run everything.
2. AWS CodeBuild: The Build Service:
This tool can help take care of compiling and testing your code, also this can also help build the project and check for errors. They can do all of these without any need for the special servers to handle the work. This means you won’t have to worry about managing your own build system.
3. AWS CodeCommit: The Source Code Repository
AWS CodeCommit is where you store your code. It’s like a safe online place where you keep the latest version of your project. You can also use other tools like GitHub or Bitbucket if you prefer. CodePipeline can easily connect to these as well.
Step-by-Step Implementation of a Serverless CI/CD Pipeline on AWS:
Here, we have discussed the step-by-step process for implementing the serverless CI/CD pipeline on AWS. You can also learn this from the AWS DevOps Course Syllabus for implementing this in your organization:
Setting Up the Source Repository:
You can begin by creating or connecting with the source repository. If using AWS CodeCommit, create a new repository via the AWS Console. For GitHub, integrate AWS CodeStar for secure authentication. Also, store your Lambda function code, SAM templates for the infrastructure, and a buildspec.yml file (which specifies build commands) in the root of your repository.
Creating the Build Specification:
The buildspec.yml file is central to the build process, and this explains building the environment, installation steps, as well as building the commands. For example, in the case of a Node.js Lambda function, you would install the SAM CLI and any dependencies, build the application with SAM build, and package it for deployment using SAM package.
Configuring AWS CodeBuild:
Navigate to the AWS CodeBuild console and create a new build project. You can connect it to your repository and select the appropriate environment (such as Node.js, Python, etc.). Specify the buildspec.yml file in the repository. Attach an IAM role with permissions for accessing S3 (for storing build artifacts), invoking Lambda functions, and interacting with CloudFormation for deployments. Create a dedicated S3 bucket to store these artifacts and ensure the IAM role has appropriate permissions to write to it.
Building the CodePipeline:
In the CodePipeline console, create a new pipeline. Start with the Source Stage, where you connect your source repository (e.g., CodeCommit, GitHub) and set it to monitor a branch. For the Build Stage, select the previously created CodeBuild project. CodeBuild will use the buildspec.yml configuration to build the code and upload artifacts to S3. Add the Deploy Stage, selecting CloudFormation to create or update a stack using your SAM template and specifying the location of your packaged template in S3.
Apart from this, if you are looking to make a career in this field, then you should make a query about the AWS DevOps Certification Cost. As per the different levels of learning, this may vary from ₹7,000 – ₹8,000 to ₹22,000 – ₹23,000 in India.
Conclusion:
If you are looking to build a serverless CI/CD pipeline on AWS, it is a powerful as well as cost-effective way for modern software deployment. Taking the AWS DevOps Certification Training is worth for the same. If you are using CodePipeline, CodeBuild, SAM, and Lambda, you can automate your build, test, and deployment process without managing the servers. This approach is helpful in reducing the operational overhead but also increases deployment speed and consistency. Also, this empowers the teams to offer the new features that fix faster with confidence.
