In 2026, AWS expanded the regional availability of the latest EC2 C8id and M8id instances within Asia Pacific and Canada. Both instance types offer triple the virtual CPUs, memory, and NVMe SSD local storage compared to previous sixth-generation variants. They deliver up to 43% improved compute performance and 3.3 times higher memory bandwidth over C6id and M6id generations, accelerating I/O-intensive database and analytics workloads.
C8id instances targeted compute-heavy tasks such as video encoding and media processing, while M8id suited balanced compute-memory workloads including data logging. Similar to R8id instances, these also support Elastic Fabric Adapter networking on larger sizes and allow 25% bandwidth adjustment to optimize workload performance.
