I have a program that I run only 1-2 hours a day. Is there a way to suspend the Azure server so I don't pay for it, then resume it later? How fast is it to suspend and then resume?
To clarify here, Azure no longer charges for stopped VMs. The billing change was announced in 2013 on Scott Guthrie's blog: No Charge for Stopped VMs.
This means you can use the portal or APIs to stop a VM without deallocating the resource - and avoid charges at the same time.
