Building a scale set

“

- [Instructor] When building solutions using virtual machines, if we want to make them scalable, we essentially have two main options. First, we can create a load balancer or we could create a scale set. When we use a load balancer, we build the virtual machines ourselves, and we then place them behind the load balancer. And this is great for resilience. And if you need to scale up or down, then you simply create a new virtual machine or remove one. But this isn't very dynamic. So Azure Scale Sets effectively do the same thing, that is they have virtual machines behind a load balancer. But the scale set mechanism automatically creates or destroys the virtual machines in response to either a set schedule or in response to load on the VMs in the scale set. So if the load increases, it adds additional virtual machines or it removes them when things get a bit quieter. So because of this, the VMs themselves need to be able to be created or spun up automatically without you manually…
