 # What are virtual machine scale sets?
+
 Azure virtual machine scale sets let you create and manage a group of load balanced VMs. The number of VM instances can automatically increase or decrease in response to demand or a defined schedule. Scale sets provide high availability to your applications, and allow you to centrally manage, configure, and update a large number of VMs. With virtual machine scale sets, you can build large-scale services for areas such as compute, big data, and container workloads.
 
+> [!IMPORTANT]
+> This article is about virtual machine scale sets in Uniform orchestration mode. To learn more about Flexible scale sets, go to [Flexible orchestration mode for virtual machine scale sets](../virtual-machines/flexible-virtual-machine-scale-sets.md).
 
 ## Why use virtual machine scale sets?
 To provide redundancy and improved performance, applications are typically distributed across multiple instances. Customers may access your application through a load balancer that distributes requests to one of the application instances. If you need to perform maintenance or update an application instance, your customers must be distributed to another available application instance. To keep up with extra customer demand, you may need to increase the number of application instances that run your application.

 This article provides an overview of the availability options for Azure virtual machines (VMs).
 
-## Availability zones
 
+## Availability zones
 [Availability zones](../availability-zones/az-overview.md?context=/azure/virtual-machines/context/context) expands the level of control you have to maintain the availability of the applications and data on your VMs. An Availability Zone is a physically separate zone, within an Azure region. There are three Availability Zones per supported Azure region. 
 
 Each Availability Zone has a distinct power source, network, and cooling. By designing your solutions to use replicated VMs in zones, you can protect your apps and data from the loss of a data center. If one zone is compromised, then replicated apps and data are instantly available in another zone. 
 
-## Availability sets
-An [availability set](availability-set-overview.md) is a logical grouping of VMs that allows Azure to understand how your application is built to provide for redundancy and availability. We recommended that two or more VMs are created within an availability set to provide for a highly available application and to meet the [99.95% Azure SLA](https://azure.microsoft.com/support/legal/sla/virtual-machines/). There is no cost for the Availability Set itself, you only pay for each VM instance that you create.

 ## Load balancer
 Combine the [Azure Load Balancer](../load-balancer/load-balancer-overview.md) with an availability zone or availability set to get the most application resiliency. The Azure Load Balancer distributes traffic between multiple virtual machines. For our Standard tier virtual machines, the Azure Load Balancer is included. Not all virtual machine tiers include the Azure Load Balancer.
