● Notice
- There is a limit to the number of frontends you can add to a Load Balancer. For more details, refer to the Load Balancer section in the service limits documentation.
- Public IP addresses are subject to associated charges. For more information, see IP address pricing:

Standard Load Balancer
| Resource | Limit |
|---|---|
| Load balancers | 1,000 |
| Frontend IP configurations | 600 |
| Rules per resource (Load Balancer + Inbound NAT) | 1,500 |
| Rules per NIC (across all IPs on NIC) | 300 |
| HA port rules | 1 per internal frontend |
| Outbound rules per Load Balancer | 600 |
| Backend pool size | 5,000 |
| Global Azure Load Balancer backend pool size | 300 |
| Backend IP configurations per frontend 1 | 10,000 |
| Backend IP configurations across all frontends | 500,000 |
1 Backend IP configuration is counted across all Load Balancer rules, including load balancing, inbound NAT, and outbound rules. Each rule is configured so that a backend pool instance is counted as a single configuration.
The Load Balancer does not enforce a throughput limit. However, throughput limits still apply to virtual machines and virtual networks. For more information, see Virtual machine network bandwidth.
Gateway Load Balancer
| Resource | Limit |
|---|---|
| Connected resources per Load Balancer (combined LB frontend configurations or VM NIC IP configurations) | 100 |
All limits for Standard Load Balancers also apply to Gateway Load Balancers.
Basic Load Balancer
| Resource | Limit |
|---|---|
| Load balancers | 1,000 |
| Rules per resource | 250 |
| Rules per NIC (across all IPs on NIC) | 300 |
| Frontend IP configurations 3 | 200 |
| 백 엔드 풀 크기Backend pool size | 300 IP configurations, single availability set |
| Availability sets per Load Balancer | 1 |
| Load Balancers per VM | 2 (1 public and 1 internal) |
3 The limit for a single disjoint resource in a backend pool (standalone VM, availability set, or virtual machine scale set placement group) is a maximum of 250 frontend IP configurations across a single Basic public Load Balancer and a Basic internal Load Balancer.
