BellJar: A new framework for testing system recoverability at scale

Building infrastructure that can easily recover from outages, particularly outages involving adjacent infrastructure, too often becomes a murky exploration of nuanced fate-sharing between systems. Untangling dependencies and uncovering side effects of unavailability has historically been time-consuming work. A lack of great tooling built for this, and the rarity of infrastructure outages, makes reasoning about them [...] Read More...

Inside Meta’s first smart glasses

Gambar
What’s new: Meta is sharing the inside story of how it developed the Ray-Ban Stories smart glasses. Why it matters: Creating Ray-Ban Stories meant Meta’s engineers had to take on new challenges to build smart glasses that married complex engineering dynamics. How do you make something that features cameras, microphones, audio, and touch controls, all [...] Read More...

Post-quantum readiness for TLS at Meta

Gambar
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...

Maintaining large-scale AI capacity at Meta

Gambar
Meta is currently operating many data centers with GPU training clusters across the world. Our data centers are the backbone of our operations, meticulously designed to support the scaling demands of compute and storage. A year ago, however, as the industry reached a critical inflection point due to the rise of artificial intelligence (AI), we [...] Read More...
