Microservices have become the dominant architectural paradigm for building large-scale distributed systems, but until now, their inner workings at major tech companies have remained shrouded in mystery. A recent new paper by Huye et. al - researchers at Tufts University and Meta - provides an unprecedented look under the hood at Meta's massive microservices architecture.

Personal data processing forms the backbone of many big tech service providers. Tech giants like Netflix, Meta, and Amazon employ intricate networks of microservices to automatically process user data, creating complex data flows that span multiple layers of computation.
