Compute
VM Scale Sets
A fleet of identical virtual machines, sized automatically according to the load you receive.
What VM Scale Sets covers
One template, many instances
Every machine in the fleet comes from the same template. The fleet stays homogeneous, and a change to the template applies to the next instances.
Follows the load
The instance count rises as demand grows and falls back when it drops, within the bounds you have set.
Failed instances replaced
An instance that stops answering is detected then replaced, without interrupting the service your users see.
