Azure Websites - Scale Up vs. Scale Out

Question

Can anyone help me with some information when it is ideal to scale out vs scale up. When to you which one?

Answer 1

The chances of one VM going down due to any failures is much bigger as compare to VM which running on load balancer will minimize the chance, So scale out is the best chance. Whereas, If you scaling up the server with medium server will not the right option.

I hope this will work.
