Virtual Machine Scale Sets

Question 1

What is a VM scale set?

Answer 1

A VM scale set is a group of identical load-balanced virtual machines that can be automatically created and managed to handle varying demands.

Question 2

What is the purpose of a VM scale set?

Answer 2

The main purpose of a VM scale set is to automatically handle increased or decreased usage of applications as demand fluctuates.

Question 3

How does a VM scale set work?

Answer 3

A VM scale set creates multiple identical VMs automatically, manages them centrally, and ensures they are behind a load balancer to distribute traffic evenly.

Question 4

What is horizontal scaling?

Answer 4

Horizontal scaling, supported by scale sets, involves creating additional copies of VMs to spread the load rather than increasing resources on a single machine (vertical scaling).

Question 5

What are the benefits of using VM scale sets?

Answer 5

Benefits include easy management of identical VMs from a central location, high availability, zone redundancy, auto-scaling based on demand, and the ability to run up to 1000 VMs in a single set without additional service costs.

Question 6

How are cloned VMs created in a scale set?

Answer 6

Cloned VMs can be created from a baseline image or configuration script, or a combination of both methods, to automate the setup of new VM instances.
