Introducing AWS CodeCommit - Amazon managed SaaS Git

AWS CodeCommit is a version control system, which is managed by Amazon Web Services, where we can privately store and manage assets in the Cloud and integrate with AWS. It is a highly scalable and secure VCS that hosts private Git repositories and supports the standard functionality of Git, so it works very well with your existing Git-based tools.

The following are the benefits of CodeCommit:

• Managed service: CodeCommit is fully managed, distributed, fault tolerant, and carries no administrative overhead. It is elastic (able to adapt to a high workload) and, as mentioned, integrated with other AWS services.
• No limit to storage and file type: We can store as many files as we want, because CodeCommit does not have space limitations. We can store not only source code but also documents and binary files.
• Data and access security: CodeCommit repositories are encrypted while they are in AWS CodeCommit or when getting cloned somewhere. It is also integrated with IAM for user-level or specific API-level security.
• HA (high availability): Whatever data we push into the repository, it will replicate across AZs (Availability Zones).
• Easy migration of Git-based repository: We can easily migrate a remote Git-based repository to AWS CodeCommit.

These are some limitations or drawbacks of self-hosted VCS (BitBucket/GitHub/GitLab), which you won't find in AWS CodeCommit:

• We may have to pay a license fee on a per-developer basis
• We may end up with high hardware maintenance costs and high support staffing costs
• Limitation on the amount and types of files that can be stored and managed
• Limitation on the number of branches, the amount of version history, and other related metadata that can be stored
