Presentation: Hardware & Provisioning Engineering @Twitter


10:35am - 11:25am



Twitter operates hundreds of thousands of servers. At that scale, repairs and reallocations are frequent and each requires a re-installation of the system. The Provisioning Engineering system at Twitter, called Wilson, is designed to handle every part of a server's lifecycle that does not require a person with a screwdriver. From bios updates to RAID controller configuration and OS installation, the Wilson stack does it all. Combined with our machine metadata service Audubon, Provisioning Engineering provides the one interface for service owners needing to interact with hardware.
