The newest generation of Amazon Elastic Compute Cloud EC2 C7gn instances, powered by AWS Graviton processors, are now generally available, according to AWS. For network-intensive workloads, Amazon EC2 C7gn instances with the new 5th generation AWS Nitro Cards offer the highest network bandwidth, the best packet-processing speed, and the best pricing. Compared to equivalent current generation x86-based network optimised instances, C7gn instances offer up to 200 Gbps network bandwidth and up to 3x greater packet-processing speed per vCPU. The AWS Nitro System is the foundation for Amazon EC2 C7gn instances.
The Nitro System is a group of AWS-designed technological advancements in hardware and software that enables the delivery of effective and adaptable cloud services with improved security, isolated multi-tenancy, private networking, and quick local storage. Utilise the improved networking capabilities to grow throughput and performance while reducing operating costs for applications that are network-intensive. Network virtual appliances, data analysis, and CPU-based artificial intelligence and machine learning (AI/ML) inference are a few workload examples.
C7gn instances come in 8 distinct instance sizes for greater scalability. These instances provide Amazon Elastic Block Store (EBS) with up to 40 Gbps of bandwidth. For applications deployed on densely connected clusters, C7gn instances offer Elastic Fabric Adapter (EFA) networking on the 16xlarge scale, resulting in decreased latency and increased cluster performance.
