AWS First Steps
Region expansion

Amazon EC2 C8g instances now available in additional regions

Amazon EC2 C8g instances are now available in AWS Asia Pacific (Taipei, New Zealand) and AWS GovCloud (US-East) regions. Powered by AWS Graviton4 processors, these instances deliver up to 30% better performance compared to Graviton3-based instances.

Amazon Elastic Compute Cloud (Amazon EC2) C8g instances are now available in AWS Asia Pacific (Taipei, New Zealand) and AWS GovCloud (US-East) regions. Powered by AWS Graviton4 processors, they deliver up to 30% better performance than AWS Graviton3-based instances. Built on the AWS Nitro System, they offload CPU virtualization, storage, and networking to dedicated hardware and software, enhancing workload performance and security. These instances support compute-intensive workloads such as high-performance computing (HPC), batch processing, gaming, video encoding, scientific modeling, distributed analytics, CPU-based machine learning (ML) inference, and ad serving. They offer larger instance sizes with up to three times more vCPUs and memory than Amazon C7g instances and provide up to 50 Gbps enhanced networking bandwidth and 40 Gbps bandwidth to Amazon Elastic Block Store (Amazon EBS). The AWS Graviton4 processor is up to 40% faster for databases, 30% faster for web applications, and 45% faster for large Java applications compared with AWS Graviton3 processors. C8g instances are available in twelve sizes, including two bare metal options.

Why it matters

Amazon EC2 C8g instances are designed for compute-intensive workloads, particularly for high-performance computing and CPU-based machine learning inference.
