I have multiple website on azure, and I wonder if there is any way to limit the bandwidth usage, for example pause the website if the bandwidth exceeds a certain value?
Is that something i can do through azure portal?
I have a pay as you go account.
No, Azure Web Sites does not offer a way to limit the bandwidth explicitly. You can "implicitly" limit the bandwidth by using smaller instances, which have less throughput.
Why are you trying to limit the outgoing bandwidth? Is it for containing costs?
