Google Axion is Google’s own processor family based on the Arm architecture for Compute Engine. With Axion, Google enters the same market that AWS opened with Graviton and Microsoft with Cobalt: custom-designed, energy-efficient Arm processors for cloud workloads.
What are Google Axion Processors?
The first generation, C4A, is based on the Arm Neoverse V2 architecture (Arm v9) and is optimized for demanding, cloud-native workloads. With N4A, based on Arm Neoverse N3, Google introduced a second instance family focused on price-performance and energy efficiency. C4A metal additionally covers bare-metal use cases. Google states significant price-performance and per-watt efficiency advantages for the Axion families compared to current x86 instances; exact percentages vary by workload and should be verified with your own benchmarks.
Core Features
- Multiple instance families: C4A (Arm Neoverse V2) for high performance, N4A (Arm Neoverse N3) for optimized price-performance, C4A metal for bare metal
- Mature Arm64 ecosystem: Docker, Kubernetes, and GKE fully support Arm64; common languages (Go, Java, Python, Node.js, Rust) and database engines (PostgreSQL, MySQL, Redis) run natively
- Broad regional availability: Axion instances are available in numerous regions worldwide, including several EU locations
- Seamless integration: GKE node pools, Cloud Run, Cloud SQL, managed instance groups, and compute features like live migration and committed use discounts work the same as on x86 instances
Typical Use Cases
Cost-optimized general-purpose workloads: Organizations looking to reduce cloud costs migrate suitable workloads to Axion instances without application changes.
Web servers and API backends: Stateless, horizontally scaling applications benefit particularly from the efficiency advantage of the Arm architecture.
Containerized microservices on GKE: Arm64 node pools integrate seamlessly into existing GKE clusters.
Compilation workloads and CI/CD: Compute-intensive build pipelines run cost-efficiently on Axion instances.
Benefits
- Lower costs at comparable or better performance versus x86 instances
- Better energy efficiency per watt
- Broad software and ecosystem support for Arm64
- No application changes needed for most cloud-native workloads

Frequently Asked Questions
What are Google Axion Processors?
Google Axion is Google's own processor family based on the Arm architecture for Compute Engine. It now spans multiple instance families, including C4A (Arm Neoverse V2) and N4A (Arm Neoverse N3), plus C4A metal for bare-metal use cases. With Axion, Google enters the same market that AWS opened with Graviton and Microsoft with Cobalt.
How do C4A and N4A differ?
C4A is based on Arm Neoverse V2 and is designed for demanding, high-performance general-purpose workloads. N4A uses the newer Arm Neoverse N3 and is optimized for price-performance and energy efficiency. Google states noticeable price-performance and per-watt efficiency gains for both families compared to current x86 instances; exact percentages depend on workload and instance type and should be verified with your own benchmarks.
Which applications are a good fit for Axion instances?
Arm64 compatibility is no longer a barrier for most cloud-native applications today. Web servers, API backends, containerized microservices on GKE, CI/CD and compilation workloads, and many database engines run natively on Arm and benefit most from the cost-efficiency advantage.
In which regions are Axion instances available?
Axion-based instances such as C4A are now available in a large number of Google Cloud regions, including several locations in North America, Europe (including Germany, Belgium, the Netherlands, and France), Asia Pacific, and Africa. Check the exact availability per instance type and region in the Google Cloud documentation before deployment.
What does it cost to run Axion instances?
Axion instances are billed like regular Compute Engine instances on a usage basis (per vCPU/hour and memory), including standard discount models such as committed use discounts. Exact prices vary by instance family, region, and configuration and are listed on the official pricing page.
