Yandex Network Load Balancer has the following limits:
- Quotas are organizational restrictions that can be changed by technical support.
- Limits are technical limitations due to Yandex Cloud architectural features. You cannot change the limits.
If you need more resources, you can increase quotas in one of the following ways:
- Generate a request for a quota increase. You must have the
quota-manager.requestOperatorrole or higher, such aseditororadmin. - Contact technical support and tell us which quotas you want increased and by how much.
Quotas
| Type of limit | Value |
|---|---|
| Number of load balancers per cloud | 2 |
| Number of target groups per cloud | 100 |
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 single target group may 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.
A resource will not be directly available on the target port if you add it to the internal load balancer's target group.
You can create a load balancer without a listener.
Health checks are transmitted from the 198.18.235.0/24 and 198.18.248.0/24 IP address ranges.
When connecting resources to the load balancer, keep in mind the limit on the maximum number of concurrent TCP/UDP connections per VM.
