AWS introduced the C9g and C9gd instances in its Asia Pacific (Tokyo) region, powered by the fifth-generation Graviton5 processors optimized for compute-intensive tasks. These instances offer up to 25% better compute performance compared to their predecessors based on Graviton4, particularly improving database, web application, and machine learning workloads by up to 35%.
Built on the sixth-generation AWS Nitro System, C9g instances target workloads like high-performance computing and real-time analytics, while C9gd adds NVMe-based local SSD storage for workloads requiring fast scratch and cache storage. AWS claims the first use of Nitro Isolation Engine adds mathematically proven security for workload isolation, though independent verification details were not provided.
