Azure Load Balancer

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’s 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, inline DDoS, firewall and more.

Basic Load Balancer

For small-scale applications that don’t need high availability or redundancy, choose the Basic tier.

Simplify load balancing for applications

Create highly available and scalable applications in minutes with built-in application load balancing for cloud services and virtual machines. Azure 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

Load Balancer automatically scales with increasing application traffic. Without you needing to reconfigure or manage the load balancer, your applications provide a better customer experience.

Use internal load balancer

Use the internal load balancer for traffic between virtual machines inside your private virtual networks, or use it to create multi-tiered hybrid applications.

Build highly reliable apps using global anycast

Load Balancer probes the health of your application instances, automatically takes unhealthy instances out of rotation and reinstates them when they become healthy again. Use Global Load Balancer 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-balanced IPv6 Internet connectivity all the way to native IPv6 endpoints on your Azure virtual machines. Native dual-stack endpoints help to meet regulatory requirements and to address the fast-growing number of devices in mobile and 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 that you’re familiar with or choose from others that fit your needs.
