  • New EC2 C9g and C9gd instances powered by AWS Graviton5 processors

    Amazon EC2 C9g and C9gd instances are now generally available, featuring AWS Graviton5 processors. C9g instances are compute-optimized, offering up to 25% higher performance per vCPU, DDR5 memory, larger L3 cache, and improved packet-processing performance. C9gd instances provide the same compute benefits along with high-speed local NVMe SSD storage.

  • Nitro Isolation Engine for enhanced security and isolation

    C9g and C9gd instances introduce the Nitro Isolation Engine, an enhancement to the Nitro System designed to enforce isolation between virtual machines. This feature uses formal verification to provide mathematical assurances of isolation for memory, CPU state, and I/O devices.

  • Enhanced memory, network, and EBS bandwidth

    These new instances feature the fastest memory available in cloud processors, DDR5 8800MT/s DIMMs. They also offer up to 15% higher network bandwidth and 20% higher EBS bandwidth on average compared to previous generations, with the largest sizes reaching 100 Gbps network and 72 Gbps EBS bandwidth.

  • Instance Bandwidth Configuration (IBC) for performance optimization

    Instance Bandwidth Configuration (IBC) allows users to adjust the allocation of bandwidth between Amazon EBS and Amazon VPC networking by up to 25%. This feature helps optimize performance for specific workloads like databases and caching.
