One of the best offerings by Microsoft, which enables Auto-Scaling of VMs
What do you like best?
Its one of the best tool to auto -scale all your clusters /VM's easily and the thing you don't need to bother much .
In this you just need to provide some limits and automatically the Azure VM Scale Set will take care of it.
We have multiple nodes in our clusters and it takes very less time to scale them up / down as per needs.
What do you dislike?
It takes some time to understand the entire process and also it does not affects immediately i.e. it takes around 2-3mins for a new node to spun up.
What problems are you solving with the product? What benefits have you realized?
Without Azure VM Scale Sets, we found that auto scaling of nodes in our cluster was not at all possible, whenever we had to scale up our cluster we had to manually increase the number of nodes. To do it automatically, VMSS was of great help to us.
