Amazon EC2 is transitioning On-Demand Instance limits from the current instance count-based limits to new vCPU-based limits to simplify the limit management experience for Amazon Web Services customers. Usage toward the vCPU-based limit is measured in terms of number of vCPUs (virtual central processing units) for the Amazon EC2 Instance Types launched.
On-Demand Instance usage toward the vCPU-based limit is measured in terms of the number of virtual central processing units (vCPUs) attached to your running instances, making it easier to take advantage of Amazon EC2’s broad selection of Instance Types. In addition, there are only five different On-Demand Instance limits—one limit that governs the usage of standard instance families such as A, C, D, H, I, M, R, T, and Z, and one limit per specialized instance family for FPGA (F), graphic-intensive (G), general purpose GPU (P), and special memory optimized (X) instances. You can continue to view and manage your limits from the Amazon EC2 console. With Amazon CloudWatch metrics integration, you can also monitor EC2 usage against limits as well as configure alarms to warn about approaching limits.
The EC2 vCPU-based limits are available in the Amazon Web Services China (Ningxia) Region, operated by NWCD, and the Amazon Web Services China (Beijing) Region, operated by Sinnet.
