Recommended Node Specifications

Recommended Specifications for Exclusive Nodes:

The performance of ASM is closely related to the cluster control plane (master nodes). Select appropriate node specifications based on your service requirements.

Total QPS (requests per second) 0-20,000 20,000-60,000
Specifications 8 vCPUs and 16 GB memory 16 vCPUs and 32 GB memory

Note

  • The total QPS is the sum of requests of all services in all applications per second in a cluster.
  • The function of recommending a proper amount of memory resources on the control plane based on the number of application service instances is coming soon.

ingressgateway Resource Consumption Reference

The resource consumed by each ingressgateway pod is affected by the connection type, number of connections, and QPS. For details, see the following tables:

Table 1 Memory consumption of persistent connections
Connections Memory Usage (MB)
1 0.055
1,000 55
10,000 550
Table 2 CPU and memory usage of short connections
QPS CPU Usage (m) Memory Usage (MB)
100 30 100
1,000 300 100
10,000 3,000 150

The preceding data is for reference only. The actual resource consumption depends on the actual service model.
