The nirvana state of system uptime at peak loads is known as “five-nines availability.” In its pursuit, IT teams hover over system performance dashboards hoping their preparations will deliver five nines—or even four nines—availability. SLOs define the performance margins you need to achieve, such as five-nines uptime.

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?

However, the key insight here is that these caches are partially shared among the CPUs, which means that perfect performance isolation of co-hosted containers is not possible. Traditionally it has been the responsibility of the operating system’s task scheduler to mitigate this performance isolation problem.
