Azure Load Balancer is free of charge, but is not provided along with the basic Virtual Machine.
Classic public load balancing
Every cloud service can obtain a free public load balancing IP (VIP). If you want to load balance on multiple VIPs, you may obtain extra VIPs for the nominal charges listed here.
You may distribute at most 5 extra IPs to your Load Balancer.
Classic internal Load Balancing
Load balancing between Virtual Machines that reside inside of a Virtual Network (Internal Load Balancing) is free of charge. Currently, adding extra VIP to Internal Load Balancing is not supported.
Standard Load Balancer
The Standard Load Balancer offers customers several benefits over the Basic Load balancer:
- More flexible and larger backend pools
- HA Ports rules for scale and resiliency of Network Virtual Appliances and other scenarios
- AZ scenarios including cross-zone load balancing, automatic zone-redundant frontends and outbound flows with a single regional IP address
- Integrated monitoring (traffic counters, health probe, TCP connection attempts, outbound connections) and continuous data plane health measurements
The pricing for Standard Load Balancer is based on number of rules configured (load balancer rules and NAT rules) and data processed.
However, there is no hourly charge for the Standard load balancer itself when no rules are configured.
Load Balancing rules:
First 5 rules: ￥ 0.159/hour
Additional rules: ￥ 0.0636/rule/hour
NAT rules: ￥ 0.0636/each
Data processed: ￥ 0.0318 per GB
