AWS CI/CD Services & AWS CodePipeline Deployment Steps

In this AWS article, we will be discussing AWS CI/CD Services in-depth, AWS CodeCommit, AWS CodeDeploy, AWS CodePipeline, and so much more. We will be exploring the following questions as well so keep reading:

  • What is CI and CD in AWS?
  • What kind of AWS CI/CD services are present?
  • Frequently Asked Questions (FAQs).

Commonly mentioned as AWS, Amazon Web Services is one of the three major cloud computing and storage providers globally. The other two cloud providers are Google Cloud and Microsoft Azure.

The best reason to choose AWS among its competitors is its wide variety of tools and services. These services are offered with helpful guides to assist all kinds of cloud users and improve their experience using AWS.

What Is CI and CD in AWS?

Continuous integration and continuous deployment/delivery can be the best thought similar to a pipeline of different operations for the code to get to the production-ready phase.

A new code is offered to the system; it goes through a sequence of steps: source, build, test, staging, and finally, production. The code is deemed okay for submission and is published as product-ready once it has passed through all the stages.

As the code progresses through the procedure set in place, passing all requirements and vetting successfully, the higher is the chance of it getting verified in the later steps.

It can be difficult for the code to progress if there has been a problem discovered in the early stage of the code in the pipeline.

In case the software does not perform as it should and fails a step, the development team is informed, and the code is halted from progress in the pipeline.

The AWS CI/CD pipeline architecture

The AWS CI/CD pipeline architecture is similar to that mentioned above. AWS offers developers and users fantastic tools to easily further software development and release phases of updates.

These changes are made based on the model of release defined by the user. This has enabled developers to easily and rapidly release new updates and upgraded features. 

Every CI/CD pipeline step is structured with a specific logic and purpose in the delivery system. Each stage acts as a checking guard for a particular facet of the code.

What are the services in AWS CI/CD?

There are different AWS CI/CD services and applications for building, managing, testing, and deploying data. The main AWS services that make up the AWS CI/CD pipeline architecture are:

AWS CodePipeline

AWS CodePipeline is a completely managed continuous service, similar to AWS CodeBuild, that is used for continually delivering quick and reliable code application and infrastructure updates.

AWS CodePipeline automates the building, testing, and deployment stages of the process every time a change has been made in the release model.

This feature has allowed developers to deliver fantastic features and updates without extra hassle. AWS CodePipeline can also integrate easily with third-party applications such as GitHub or with your business’s custom plugins.

AWS CodeCommit

AWS CodeCommit is the central repository service provided in AWS. It is secure, highly available backed by GitHub repository.

This service helps the team members to collaborate their work in a central repository backed by AWS and for sure secure, as it’s encrypted.

It is exactly the same as git with all the commands being the same it’s pretty easy to use.

AWS CodeBuild

AWS CodeBuild is a popular web service by Amazon and an uninterrupted integration service that compiles source code, runs coding tests, and produces complete software packages which are ready for deployment.

AWS CodeBuild eases the process of provisioning, managing, and scaling your own servers. It has the capability to scale itself continuously while also processing various builds and versions simultaneously.

AWS CodeDeploy

AWS CodeDeploy is another popular service from the AWS CI/CD services. It is a completely managed code deployment service that can automate software deployments on several platforms.

These deployments can be made on Amazon Lambda, Amazon EC2, AWS Fargate, and even a private on-site server.

AWS CodeDeploy has provided users the ease to release new features and updates rapidly. All of this can be accomplished while avoiding downtime during application deployment and complexities in updating applications.

Error-prone manual operations can be eliminated with AWS CodeDeploy features to automate software deployments.

Resources for AWS CI/CD Pipeline Tutorial / AWS CodePipeline tutorial.

The most reliable AWS Codepipeline Tutorials are on the AWS Get Started pages. You can find great resources and tutorials for beginner and advanced levels on the platform.

The most common and easy resource for AWS CodePipeline is this user guide. You will learn how to set up a pipeline on AWS using the services from AWS CodePipeline. After following this guide, you will be able to extract code from a source repository to deploy it to an Amazon EC2 instance.

If you are a complete beginner in the AWS field, you may want to start from the fundamentals here. This link will direct you to the getting started guide to learn about the AWS fundamentals and begin building on your knowledge of Amazon Web Services.

AWS cI/cD pipeline vs jenkins

Jenkins is one of the most widely used ci/cd pipelines for deployment across environments. Let’s check out the differences/pros/cons between AWS Pipeline and Jenkins.

AWS Code PipelineJenkins
Web-Based in AWS EnvironmentHas to set up Jenkins Server
Fully Integrated with AWS as it sits inside the AWS ecosystemCapable to deploy in any of the system, cloud, and on-premises as well
Easy Setup as its web-basedComplicated setup, involving server and plugins as well
Integrates only with GithubIntegrates with Github along with other tools

How to deploy an application using cI/cD pipeline

Follow along to create a CodePipeline to deploy the application in AWS:

Step 1: Jump into the AWS console and open the CodePipeline page.

AWS CodePipeline
AWS CodePipeline – Create

Step 2: Hit the Create Pipeline button and you could see the below page. Give a relevant name to your pipeline, either select the role if you have created (Ideal Case) else let AWS create the role for you, then hit next.

AWS CodePipeline – Settings

Step 3: Choose the source from where you would like to pull up your source code into the CodePipeline.

AWS CodePipeline - Source
AWS CodePipeline – Source

Step 4: We are going with selecting AWS CodeCommit, enter the Repository name and the branch from where you would like to pull the code. Select the other details as per your preference, we are going with the default selection here.

Step 5: In here you would have to make a selection of building the code, either AWS CodeBuild or Jenkins depending on the Clients preference.

AWS CodePipeline - CodeBuild
AWS CodePipeline – CodeBuild

Step 6: If you are selecting CodeBuild, you have to go for the below additional setup. Here you have to provide the name of CodeBuild along with the buildspec.yaml file.

A buildspec.yaml file contains the build commands and specs which the CodeBuild uses and converts the code provided as the source. CodeBuild cannot succeed without this file and produce the desired output that can be deployed.

Fully Managed by AWSSometimes cloud goes offline creating problems.
Non-License based, any number of users with access can use it.Stops all users once the number of licensed users has surpassed.
Good in Code-Repository, Build, and Deployment as well.Good Code-Repository

Frequently Asked Questions (FAQs)

Q1: What is CI/CD Pipeline?

CI/CD stands for Continuous Integration and Continuous Deployment, that is as soon as a code is pushed in the repository, it builds the code and if the testing is passed the code is deployed to the stipulated environment.
