Making Distributed Priority Queue Disaster Ready

Facebook Ordered Queue Service (FOQS) is a distributed priority queue service that powers hundreds of services and products across the Facebook stack. Facebook users have come to rely on its services to remain connected to their friends and families. As such, it is absolutely crucial for Facebook to continue operating with high availability during events which may impact its data centers. Being a core building block of Facebook infrastructure, FOQS is expected to handle loss of a data center gracefully and transparently to its clients.

Dillon and Jasmit will talk about how the architecture of FOQS has evolved to be resilient to disasters, the technical challenges of hosting a globally available system, and the operational challenges that came with migrating existing tenants of FOQS to disaster ready installations with zero downtime at Facebook scale.
