AWS CodeCommit: Your Secure and Scalable Git Repository

AWS CodeCommit: Your Secure and Scalable Git Repository

What is codecommit AWS service?

AWS CodeCommit is a fully managed Git repository service that provides secure and scalable source control for your development teams. It's a part of the AWS Code family of services, designed to streamline software development and deployment.

AWS CodeCommit Advantages & Disadvantages:

Advantages of AWS CodeCommit

Fully Managed Service: AWS CodeCommit eliminates the need to set up and maintain your own source control infrastructure. AWS handles all scaling, backup, and availability needs.

Scalability: CodeCommit automatically scales to accommodate any number of repositories and users without requiring manual intervention.

High Availability and Durability: CodeCommit ensures high availability by storing repositories in a multi-AZ (Availability Zone) environment. This guarantees that the repositories remain accessible even during outages in one zone.

Integration with Other AWS Services: CodeCommit integrates seamlessly with other AWS services such as AWS CodeBuild, AWS CodePipeline, and AWS Lambda, making it easy to create CI/CD pipelines and automate processes.

Security: Fine-grained access control is possible through AWS Identity and Access Management (IAM). You can easily manage who can access your repositories and what they can do (read/write permissions).Data in CodeCommit is encrypted both at rest and in transit.

No Size Limits: Unlike some other version control systems that may impose size limits on repositories or files, AWS CodeCommit allows for large repositories and files with no direct limitations.

Native Git Support:CodeCommit uses the Git protocol, making it compatible with most Git tools, scripts, and workflows.

Cost-Effective for Small Teams:There is no upfront cost, and you only pay for what you use. For small repositories and teams, the pricing is very competitive. The free tier offers 5 active users per month, each with up to 50 GB of storage and 10,000 Git requests.

Automatic Backup and Versioning:Your repositories are automatically backed up, and each commit represents a version of your code that you can revert to at any time.

Disadvantages of AWS CodeCommit

Limited Ecosystem Compared to GitHub/GitLab: Platforms like GitHub or GitLab offer a broader set of features (issue tracking, project management, extensive plugin ecosystems, etc.). CodeCommit focuses primarily on source control and doesn't offer as many out-of-the-box project management or collaboration features.

AWS-Centric Workflow: While CodeCommit integrates well with other AWS services, its use can be more challenging for teams working across different cloud providers or with diverse toolchains outside of AWS.

Complex IAM Permissions: Managing access control through IAM policies can be more complex compared to simple access management in GitHub or GitLab, especially for users who are unfamiliar with AWS.

Lack of a Large Community: Popular alternatives like GitHub and GitLab benefit from large user communities, which provide extensive support, forums, and third-party integrations. AWS CodeCommit has a smaller community and fewer third-party tools or extensions.

Limited UI/UX: The web interface of CodeCommit is not as feature-rich or user-friendly as some other popular Git hosting services. For instance, GitHub offers more sophisticated features for code reviews, pull requests, and collaboration.

Pricing for Larger Teams: While CodeCommit is cost-effective for small teams, it may become more expensive as the number of users grows, especially when compared to GitHub's or GitLab's enterprise plans which bundle more features.

No Built-In Project Management Tools: Unlike GitHub, GitLab, or Bitbucket, AWS CodeCommit doesn’t offer features such as built-in issue tracking, project boards, or advanced CI/CD features. These would have to be handled separately or integrated using other AWS tools.

Learning Curve for Non-AWS Users:For teams not already using AWS, the learning curve for setting up and managing CodeCommit with IAM policies, CLI, and integrations can be steeper.

Will do Practical to understand more:

Important Note Before moving ahead::AWS Code commit does not work with Root Account will not suitable for this demo Why? AWS codecommit there are some restrictions with respect to accessing them with SSH and HTTPS. Will implement the demo with the simple IAM User.

First we will try to do it with my root account and see what error would appear?

Once we click on CodeCommit then we will be able to see the console below.

Firstly we will Create a Repository here, So Click on Create Repository.

Give the Name and Description of the repository.

Do not enable the Amazon CodeGuru as of now. Then click Create.

We have received the error message like below:

Then we have installed Git on our local machine.

What we can do over here is create an IAM user and provide the specific permission to that IAM user and then try to create a repo.

Then go with the IAM user ,click on IAM user, Click on Users.

We have enabled Custom password & uncheck the users must create a new password at next sign-in . Then click on Next.

So now select the attach policies directly.

& Select the policy “ AWS CodeCommitPowerUser” & Click Next.

With Power user we can get all access like Enable Cloudwatch integration as well SNS integration.

Click Next once we attach the policy.

The user has been created successfully.

Click Create user.

Then log in with the user which we have created. Open a new tab or new incognito window to login.

Now we have logged in with the IAM user.

Search the codecommit and create the repository.

Then click on Create. Still we are unable to Create a repository over here. As we came to know that we don't have any existing repositories which have already been created. As mentioned in documents only existing customers who are having a repository created already can continue to use the service as normal.

We will try to create the repo with the AWS CLI.

Click Next.

Even While configuring with the CLI Its showing the error.

As recommended there should be existing repo created. As per the document since july 25 2024 AWS has stopped the AWS codecommit Service for the new customers.

So We will not able to move ahead to do the further practical as we don’t have the repo saved before July 25th 2024.

Thank You !!

Happy Learning!!
