About Gerrit and Google Axion C4A

Google Axion C4A Arm instances in Google Cloud

C4A is a family of Arm-based virtual machines built on Google’s custom Axion CPU, which is based on Arm Neoverse-V2 cores. Designed for high-performance and energy-efficient computing, these virtual machines offer strong performance for modern cloud workloads.

The C4A series provides a cost-effective alternative to x86 virtual machines while using the scalability and performance benefits of the Arm architecture in Google Cloud.

Gerrit

Gerrit is an open-source, web-based code review system for Git repositories that lets teams review proposed commits before they are merged into a codebase. It’s especially useful for projects that want patchset-based reviews, inline comments, approval labels, fine-grained permissions, and integration with CI/CD systems before changes land.

To learn more about how Gerrit fits into a development workflow and how to review, upload, and manage changes, start with the official Gerrit product overview and user guide.

There’s also a Basic Gerrit Walkthrough — For GitHub Users which explains the core principles of code review in Gerrit compared to pull requests.
