Modern distributed software doesn't stop at your VPC. Edge deployed software needs realtime communications, updates, and state sync. It needs RPC and PubSub over the web. Lets make it open-source. In this talk we'll cover the need for over-the-web realtime RPC and PubSub, why we needed and created it for our OpenPolicyAgent realtime updates layer, along side: - The challenges that the implementation faced - Pro/Cons of realtime update channels - Common use cases (updates, sync, event propagation, distributed computing, authorization, ...) - Additional awesome Python open-source we used in this solution (FastApi, Tenacity, broadcaster, ...) - How to use the open-source packages we shared.
