Quotas and limits
In the Yandex Network Load Balancer service, the following limitations apply:
- Quotas are organizational restrictions that can be changed by technical support on request.
- Limits are technical restrictions due to the Yandex.Cloud architecture specifics. The limits cannot be changed.
You can view your current account quotas in the management console.
Quotas
| Type of limit | Value |
|---|---|
| Number of load balancers per cloud | 2 |
| Number of target groups per cloud | 2 |
Limits
| Type of limit | Value |
|---|---|
| Number of resources per target group | 254 |
| Number of listening ports | 10 |
| Number of health checks per attached target group | 1 |
| Status check protocol | TCP, HTTP |
Other restrictions
A particular target group can only contain target resources from a single cloud network.
A target group can include resources that are connected to the same subnet within a single availability zone.
You can create a load balancer without a listener.
Health checks are transmitted from the IP address range 198.18.235.0/24.
When connecting resources to the load balancer, keep in mind the limit on the maximum number of simultaneous TCP/UDP connections per VM.
