[$] Resource control at Facebook

Facebook runs a lot of programs and it tries to pack as many as it can onto each machine. That means running close to—and sometimes beyond—the resource limits on any given machine. How the system reacts when, for example, memory is exhausted, makes a big difference in Facebook getting its work done. Tejun Heo came to 2018 Open Source Summit North America to describe the resource control work that has been done by the team he works on at Facebook.
