Part 5/12:
A key innovation was using Multicast groups, a concept borrowed from network protocols, to distribute data efficiently:
News ticks originate from exchanges and enter an on-premises multicast infrastructure.
From there, data is unicasted into cloud environments like AWS or GCP, where it is multicast again into multiple microservice instances.
This direct, hopless distribution minimizes network overhead, reducing latency, and ensures all subscribed services receive data simultaneously.
Cloud and On-Prem Integration
Data from exchanges are delivered via private multicasts into the cloud infrastructure, enabling scalable, reliable, and near-instantaneous data dissemination to end-user fronts.
