With Azure Load Balancer, you can scale your applications and create high availability for your services. Load Balancer supports inbound and outbound scenarios provide low latency and high throughput and scale up to millions of flows for all TCP and UDP applications.
Load Balancer distributes new inbound flows that arrive on the Load Balancer's frontend to backend pool instances, according to rules and health probes.
Additionally, a public Load Balancer can provide outbound connections for virtual machines (VMs) inside your virtual network by translating their private IP addresses to public IP addresses.
Azure Load Balancer is available in two SKUs: Basic and Standard. There are differences in scale, features, and pricing. Any scenario that's possible with Basic Load Balancer can also be created with Standard Load Balancer, although the approaches might differ slightly.
