Stairway to Cloud: Orleans Framework for building Halo-scale systems

on YouTube ↗01h 10m

" summary

Orleans implements a virtual actor runtime (grains) that auto-activates, pages state to storage, and guarantees single-threaded execution per actor so code needs no locks. It ships persistence providers, virtual streams, and a placement/cluster model that ran Halo production launches handling millions of players and thousands of updates/sec, scaled linearly and cut application code dramatically. Open sourced under MIT, runs on Azure/AWS/on‑prem and reports ≈50% throughput gains in some workloads.
