Display availability sets

includeAvailability Sets in Azure enable users to separate workloads for high availability. All of the VMs in an availability set must be in the same Azure Virtual Network, which means they must be in the same Abiquo virtual datacenter. To add a group of VMs to an Azure load balancer, you must have all the VMs in the same availability set. 

After an upgrade, to display availability sets that were not present in the platform with deployed VMs, the user should synchronize the virtual datacenter or networks. 

For more information about Azure Availability sets, see Azure documentation, for example, https://docs.microsoft.com/en-us/azure/virtual-machines/windows/tutorial-availability-sets .

You can create an availability set at the regional level and later assign it to a virtual datacenter.

Assign an availability set to a VM

Include PageAssign an Availability set to a VMAssign an Availability set to a VMYou can use availability sets to ensure high availability for your VMs in Azure. Each VM in the availability set will deploy on separate, isolated hardware, in a cluster. This is similar to the platform's concept of anti-affinity layers in private cloud. To attach Azure VMs to a load balancer, you must add them to the same Availability set. All of the VMs in an Availability set must be in the same Azure Virtual Network, which means they must be in the same virtual datacenter but they can belong to different Resource groups.

To create an availability set:

Go to Virtual datacenters

Go to Locations → select a location OR
select an Azure virtual datacenter

Go to Network → Availability sets

Field

Value

Name

The name of the availability set, which must be unique in your location

Location

The platform will create the availability set in Azure at the level of the cloud location.

Virtual datacenter

The virtual datacenter where you will use the availability set

Resource group

The platform will create the availability set in the selected Resource group

Fault domains

From Azure documentation: "VMs in the same fault domain share common storage as well as a common power source and network switch".

Update domains

From Azure documentation: "An update domain is a group of VMs and underlying physical hardware that can be rebooted at the same time."

For more information about Azure Availability sets, see Azure documentation, for example, https://docs.microsoft.com/en-us/azure/virtual-machines/windows/tutorial-availability-sets .

Assign an availability set to a VM

When you create a VM, you can select an Availability set. This is similar to the VM layers feature in private cloud.

...

Before you deploy the VM, to change the availability set, you can edit the VM and select another availability set.

...

If the user does not deploy the VM before the VDC is synchronized, the platform will remove the VM from the Availability set during the synchronization process.
