![]() The vCPUs of an instance within a family can range from 1 to 128 vCPUs, depending on the size. ![]() Your current vCPU limit is Running On-Demand All P instances = 64 vCPU. Therefore, your service limit increase request needs to provide you flexibility. Scenario 3: You want to test more powerful instance types, but you don't know which instances you need. Note: Replace US West with the Region you're requesting a limit increase in. Limit type: EC2 Instances Region: US West Primary Instance Type: Running On-Demand All Standard (A, C, D, H, I, M, R, T, Z) instances New limit value: 160 In this scenario, submit a vCPU service limit increase request for 160 vCPUs (64 + 96) or higher. You need 96 additional vCPUs if your account is already running 64 vCPUs worth of instances. Therefore, the additional number of vCPUs needed is calculated as follows: *.10xlarge instances = 40 vCPU per instance.*.2xlarge instances = 8 vCPU per instance.The instance-to-vCPU conversion rates for these two types of instances are as follows: Usage for these instance types is added together and governed by a single limit. Your current vCPU limit is Running On-Demand All Standard (A, C, D, H, I, M, R, T, Z) instances = 64 vCPU.īoth instance types that you want to launch are included in the "All Standard (A, C, D, H, I, M, R, T, Z) instances" limit. You want to launch two additional m5.2xlarge and two additional m4.10xlarge instance types. Scenario 2: You're currently running 64 vCPUs worth of instances. Note: Replace US West with the AWS Region where you're requesting a limit increase. Limit type: EC2 Instances Region: US West Primary Instance Type: Running On-Demand All G instances New limit value: 12 In this scenario, submit a vCPU service limit increase request for 12 vCPUs (3*4). Your account can already run two g4dn.xlarge instances, based on your G instances limit of 8. Your current vCPU limit is Running On-Demand All G instances = 8 vCPU.Ī g4dn.xlarge instance has a footprint of 4 vCPUs. You want to launch three g4dn.xlarge instances. Scenario 1: You're not currently running any G family instances. See the following example scenarios and their calculations. Resolution Example calculationsīefore you request a service limit increase, calculate the vCPU value that you need for your use case. Use this information to determine the appropriate service limit increase to request. Then, compare this number against vCPU-based limits. To request an increase, first determine the number of vCPUs that your On-Demand Instances use. You submit EC2 vCPU limit increases as a vCPU value.
