Cloud computing has become a widely-used model of computing, as it offers a number of benefits over traditional, on-premises computing systems. This means that users only pay for the computing resources they actually use, rather than having to invest in expensive hardware and software upfront.

First, a bit of operating-system design context. It is desirable for a program to be able to go to sleep and then wake up a little while later. Ideally the CPU goes to sleep when Sleep(1) is called, in order to save power, so how does the operating system (OS) wake your thread if the CPU is sleeping?
