FOQS: Making a distributed priority queue disaster-ready

Facebook Ordered Queueing Service (FOQS) is a fully managed, distributed priority queueing service used for reliable message delivery among many services. FOQS has evolved from a regional deployment into a geo-distributed, global deployment to help ensure that data stored within logical queues is highly available, even through large-scale disaster scenarios. Migrating to a global architecture [...] Read More... The post FOQS: Making a distributed priority queue disaster-ready appeared first on Engineering at Meta.

Today, the internet (like most digital infrastructure in general) relies heavily on the security offered by public-key cryptosystems such as RSA, Diffie-Hellman (DH), and elliptic curve cryptography (ECC). But the advent of quantum computers has raised real questions about the long-term privacy of data exchanged over the internet. In the future, significant advances in quantum [...] Read More...
