|They are a group of identically configured VMs that are spread across multiple fault domains.
|They are the group of discretely configured VMs that are spread across various fault domains.
|These have 5 fault domains and update domains by default.
|By default, these have 3 fault domains and 5 update domains.
|These are used when there are unpredictable workloads that require the feature of auto scalability.
|These are used when there are predictable workload requirements.
|Here, the VMs are configured and created in the same manner from the same image.
|Here, the VMs are created by making use of different images and configurations.
|The number of VMs can be increased/decreased based on the demand or the pre-defined schedule.
|A VM can be added to an availability set only at the time of the set’s creation.
|Here, the VM scale sets can be distributed across multiple data centers or within a single data center.
|Here, the VMs are automatically distributed in a data center.
