Google and CIQ created this collection of Compute Engine virtual machine (VM) images together. They're designed to give you optimal performance when using Rocky Linux on Compute Engine to run your CentOS workloads.
These new Rocky images contain customized variants of the Rocky Linux kernel and modules that optimize networking performance on Compute Engine infrastructure while retaining bug-for-bug compatibility with Community Rocky Linux and RHEL. In particular, Rocky is pre-configured to use the latest version of the Google virtual network interface (gVNIC). The high bandwidth networking enabled by these customizations will be beneficial to virtually any workload and are especially valuable for clustered workloads such as High-Performance Computing (HPC).
How fast are these high bandwidth VM instances? With 80 or more Virtual CPUs (vCPU), you'll get egress bandwidth speeds of 32 Gigabits per second (Gbps). With Tier 1, it jumps up to 100 Gbps. That's more than fast enough for most HPC uses.
Rocky Linux Optimized for Google Cloud can come with day-one support and GPUs. For customers building multi-cloud deployments, Google recommends the community Rocky images. Rocky Linux 8 Optimized for Google Cloud is available for all x86-based Compute Engine VM families. It will soon also be available for the new Arm-based Tau T2A.
Going forward, Google will publish both the community and Optimized for Google Cloud editions of Rocky Linux for every major release. Both sets of images will receive the latest kernel and security updates provided. Rocky Linux 9 images will be available shortly.
