About CPU Credit Usage

CPU Credit Example

CPU Credit Formula: CPU credit = vCPU core * usage * minutes, e.g. 1C * 10% * 60 minutes = 6 CPU credits, 1C * 15% * 30 minutes = 4.5 CPU credits

If 1 Core 0.5C runs at Baseline CPU performance 10% for 60 minutes, CPU credit accumulation is 6 credits, and if higher than baseline CPU performance (15%) runs for 30 minutes, CPU credit consumption is 4.5 credits

Baseline CPU Performance: The instance type of any t5 instance determines its baseline CPU performance, which means each vCPU core of an instance has a maximum usage for normal workloads. For example, when a t5-lc1m2.small instance is used for normal workloads, the maximum CPU usage is 10%.
CPU Credit Accumulation: When the CPU usage of a t5 instance is lower than the baseline CPU performance, the instance accumulates CPU credits because the consumption speed is lower than the CPU credit distribution rate.
CPU Credit Consumption: When the workload of a t5 instance bursts to a level above the baseline CPU performance, the instance consumes accumulated CPU credits to raise the CPU usage to meet business requirements.

CPU Credit Definition

Initial CPU Credit

Each time you create a new t5 instance, 30 CPU credits are immediately allocated to the instance, which is called initial CPU credit. Instances are only allocated initial CPU credit at the time of creation. When an instance begins to consume CPU credits, the initial CPU credits are used first.

CPU Credit Distribution

The CPU credit distribution rate is the number of CPU credits that a t5 instance obtains per minute. It is determined by baseline CPU performance.

View CPU Credits

You can view t5 instance CPU credits from the ECS console.

Expiration of CPU Credit

Once accumulated, CPU credits are saved only for 24 hours. The credit points are no longer valid after 24 hours.
