Hey, my Self Santhosh Nimmala, I am Working with Luxoft as a Principal consultant (leading Cloud and DevOps in TRM space), in coming Articles I will be explaining about DevOps and DevTools with respective to AWS it will also have real world DevOps projects with Code and common DevOps Patterns , in this blog we are going to learn about AWS code pipeline .

A code pipeline is a process that automates the building, testing, and deployment of software applications. It is a series of stages through which a codebase goes before it is released as a finished product. The purpose of a code pipeline is to automate the software development lifecycle, reducing the time and effort required to deliver high-quality software. In this article, we will dive deeper into what a code pipeline is, its benefits, and how it works.

What is a Code Pipeline?

A code pipeline is a set of automated processes that help developers quickly and efficiently develop, test, and deploy software applications. It is a continuous integration and delivery (CI/CD) pipeline that automates the software development lifecycle, from building and testing to deployment and monitoring.

Benefits of a Code Pipeline

A code pipeline offers numerous benefits, including:

1) Faster Development and Deployment Cycles: A code pipeline streamlines the development and deployment process by automating many of the tasks that would otherwise have to be done manually. This makes it possible to release new features and bug fixes more quickly, reducing the time it takes to get software into the hands of users.

2) Improved Quality and Reliability: Automated testing and deployment processes help ensure that software is thoroughly tested and reliable before it is released. This reduces the risk of bugs and other issues, improving the overall quality of the software.

3) Greater Collaboration: A code pipeline encourages greater collaboration between development, testing, and operations teams, as everyone works together to streamline the software development process. This leads to more efficient workflows and better communication between team members.

4) Increased Efficiency: By automating many of the manual processes involved in software development, a code pipeline can significantly reduce the amount of time and effort required to develop and deploy software.

How a Code Pipeline Works

A typical code pipeline consists of several stages, including:

- 
Source: This is the stage where the codebase is stored and managed using a version control system like Git.

- 
Build: In this stage, the code is compiled and built into a deployable package or artifact.

- 
Test: Automated tests are run to ensure that the code meets the necessary requirements and quality standards.

- 
Deploy: The code is deployed to a staging environment for further testing and review.

- 
Release: The code is released to production once it has passed all tests and reviews.

- 
Monitor: The application is monitored in production to ensure that it is running smoothly and to identify any issues that may arise.

A code pipeline can be set up using a variety of tools and services, including Jenkins, AWS CodePipeline, and CircleCI. These tools provide a user-friendly interface for creating and managing pipelines, as well as integrating with other tools and services like AWS CodeBuild and AWS CodeDeploy.

What advantages you get by using Codepipeline over other Orchestration tools   

CodePipeline is a popular continuous integration and delivery (CI/CD) service provided by Amazon Web Services (AWS) that automates the building, testing, and deployment of software applications. While Jenkins and other orchestration tools also offer similar features, there are several advantages to using CodePipeline over these tools. In this article, we will explore some of the key advantages of using CodePipeline for your CI/CD needs.

*
Cloud-Native Architecture
One of the main advantages of CodePipeline over Jenkins and other orchestration tools is that it is designed to work natively in the cloud. This means that it is optimized for the AWS cloud infrastructure and can easily integrate with other AWS services like CodeBuild, CodeDeploy, and Elastic Beanstalk . As a result, you can easily build and deploy your applications in the cloud without having to manage the underlying infrastructure.

*
Simple Setup and Management
CodePipeline is easy to set up and manage, even for users who have limited experience with CI/CD pipelines. Its simple web-based console provides a user-friendly interface for configuring your pipeline stages, connecting your source code repository, and setting up your build and deployment options. This simplicity makes it easier to get started with CI/CD and reduces the learning curve for new users.

*
Scalability and Flexibility
CodePipeline is designed to be highly scalable and flexible, allowing you to adjust your pipeline stages and resources based on the needs of your application. You can easily add new stages, adjust build and deployment options, and integrate with other AWS services as your application grows and evolves. This flexibility makes it easier to adapt your pipeline to changing business needs and requirements.

*
Security and Compliance
CodePipeline is designed with security and compliance in mind, providing several features that help ensure the security and privacy of your code and data. For example, CodePipeline integrates with AWS Identity and Access Management (IAM) to manage user access and permissions, and also supports encrypted pipelines and artifacts to protect your data in transit and at rest.

*
Cost-Effective
CodePipeline is a cost-effective solution for CI/CD, especially for users who are already using other AWS services. With CodePipeline, you only pay for the resources you use, and there are no upfront costs or long-term commitments required. This makes it easier to manage your costs and scale your pipeline as your application grows.

lets see how to build a code-pipeline in AWS .

1) Go to AWS console and choose codepipeline and create a project like below .

2) give Project name this will automatically create a role if you already have a role for codepipeline please give your role name by unchecking the check box .

you can see advance data about encryption and Artifact store for your project .

3) Select source for your repos where you code is hosted it codepipeline supports CodeCommit , s3 , ECR , GitHub,Github Enterprise,  bitbucket .

we have selected CodeCommit as we have our repo in it .

4) next we need to select Build tool for the project this can be codebuild or Jenkins(if you want).

we selected Codebuild as we already created a projected , if you want to create just CI pipeline you can skip deploy stage and call this as a CI pipeline

5) Next is Deploy stage you can choose various supported Providers codepipeline supports below providers .

finally click next and finally create pipeline

this pipeline will trigger whenever you have any change in repo branch like a push , merge etc.
