AWS announced new Graviton 4-powered C8gn instances designed for network-intensive applications such as cloud firewalls and load balancers. These instances provide up to 192 vCPUs and 384GB of DDR5 memory, delivering a 30 percent performance advantage over previous models. The standout feature is 600Gbps network and 60Gbps EBS bandwidth from twin Nitro 6 data processing units. The instances are tailored for workloads like virtualized firewalls and routers, utilizing a pair of 300Gbps NICs derived from higher bandwidth capabilities, ensuring efficient operation.
The C8gn instances revealed this week offer up to 192 Arm-based vCPUs across a pair of Graviton 4 processors and 384GB of DDR5 memory, providing a 30 percent performance advantage over the Graviton 3E-based C7gn instances.
AWS has pitched these instances at workloads that push and process packets, mainly for virtualized firewalls, routers, load balancers, proxy servers, and distributed denial of service prevention tools.
AWS exposes that bandwidth to the instances as what looks like a pair of 300Gbps NICs, at least on the two top specced SKUs.
Amazon has capped the network bandwidth in software so it appears to the virtual machine as a 300Gbps NIC, leaving bandwidth for another 60Gbps dedicated to EBS storage.
