Microsoft Azure Load Balancer

Published on 09 May 18

What is Azure Load Balancer?

With Azure Load Balancer you can scale your applications and create high availability for your services. Load Balancer supports inbound and outbound scenarios, provides low latency and high throughput, and scales up to millions of flows for all TCP and UDP applications.

Load Balancer distributes new inbound flows that arrive on the load balancer's front-end to back-end 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. As you learn about Load Balancer, it is important to familiarize yourself with the fundamentals and SKU-specific differences.

Why Use Load Balancer?

You can use Azure Load Balancer to:

  • Load-balance incoming internet traffic to your VMs. This configuration is known as a Public load balancer
  • Load-balance traffic across VMs inside a virtual network. You can also reach a load balancer front end from an on-premises network in a hybrid scenario. Both scenarios use a configuration that is known as an internal load balancer
  • Port forward traffic to a specific port on specific VMs with inbound network address translation (NAT) rules.
  • Provide outbound Connectivity for VMs inside your virtual network by using a public load balancer.

What are Load Balance Resources?

A load balancer resource can exist as either a public load balancer or an internal load balancer. The load balancer resource's functions are expressed as a front end, a rule, a health probe, and a back-end pool definition. You place VMs into the back-end pool by specifying the back-end pool from the VM.

Load balancer resources are objects within which you can express how Azure should program its multi-tenant infrastructure to achieve the scenario that you want to create. There is no direct relationship between load balancer resources and actual infrastructure. Creating a load balancer doesn't create an instance, and capacity is always available.

Load balancer SKU Comparision

Load Balancer supports both Basic and Standard SKUs, each differing in scenario scale, features, and pricing. Any scenario that's possible with Basic Load Balancer can be created with Standard Load Balancer as well. In fact, the APIs for both SKUs are similar and invoked through the specification of a SKU. The API for supporting SKUs for Load Balancer and the public IP is available starting with the 2017-08-01 API. Both SKUs have the same general API and structure.

However, depending on which SKU you choose, the complete scenario configuration might differ slightly. Load Balancer documentation calls out when an article applies only to a specific SKU. To compare and understand the differences.
