Basically I would like to know how to scale my website when I have many requests, since this is very successful.
When you set a web app you can define the criteria with which you must scale
Within the Azure Portal you would use the option All settings and then Scale Up
Here you should take into account according to the plan you have if you select a mode Shared or Basic
Remember that the price for the service will increase if you scale the site.
