Design Git.

A robust Git design would likely involve a distributed architecture. Core components could include a client-side application for managing local repositories, handling commits, branches, and merges. A server-side component would manage remote repositories, facilitating push and pull operations. For efficient storage, especially for large files or historical data, consider object storage solutions like Amazon S3 or a similar distributed file system. Diffs and file comparisons could be handled by dedicated microservices optimized for performance, allowing for rapid identification of changes between versions. This modular approach enhances scalability and maintainability.
