Explore Azure load balancing services and find the best solution for your workloads using an easy-to-use service selection tool

Improve availability and scalability of your applications by distributing network traffic

Load-balance internet and private network traffic with high performance and low latency. Instantly add scale to your applications and enable high availability. Load Balancer works across virtual machines, virtual machine scale sets and IP addresses.

Choose the SKU that is best for you

Standard Load Balancer

Equipped for load-balancing network layer traffic when high performance and super-low latency is needed.

Standard Load Balancer routes traffic within and across regions and to availability zones for high resiliency.

Gateway Load Balancer

Easily deploy and scale virtual appliances with Gateway Load Balancer.

Enables scenarios that need service-chaining such as analytics, DDoS protection, firewall, and more.

Basic Load Balancer

Supports small-scale applications that don't need high availability or redundancy.

Simplify load balancing for applications

Create highly available and scalable apps in minutes with built-in application load balancing for cloud services and virtual machines. Load Balancer supports TCP/UDP-based protocols such as HTTP, HTTPS, and SMTP, and protocols used for real-time voice and video messaging applications.

Get high availability and robust performance

Provide a better customer experience using Load Balancer to automatically scale your increasing app traffic. You won't need to reconfigure or manage the load balancer.

Use internal load balancer

Manage traffic between virtual machines inside your private virtual networks, or use it to create multiple-tiered hybrid applications.

Build highly reliable apps using global anycast

Get optimal performance by using Load Balancer to probe the health of your app instances. Load Balancer automatically takes unhealthy instances out of rotation and reinstates them when they become healthy again. Use globally for latency-based traffic distribution across multiple regional deployments, or use it to improve application uptime with regional redundancy.

Help secure your networks

Control your inbound and outbound network traffic and help protect private networks using built-in network address translation.

Expand your reach using IPv6

Load-balance IPv6 internet connectivity all the way to native IPv6 endpoints on your Azure virtual machines. Native dual-stack endpoints help meet regulatory requirements and address the growing number of devices in mobile and Internet of Things (IoT) markets looking to connect to Azure-based services.

Deploy network virtual appliances seamlessly

Quickly build highly scalable and available applications with Gateway Load Balancer and our industry-leading partners. As you move more workloads to the cloud, easily use the appliances you are familiar with or choose from others that fit your needs.
