Case Study: Ubisoft achieves immersive global multiplayer scale for Rainbow Six Siege with Microsoft Azure

Rainbow Six Siege uses Azure to deliver immersive multiplayer games globally

Ubisoft’s Rainbow Six Siege is a fast‑paced, multiplayer shooter that grew rapidly from launch into a global eSports phenomenon, creating a demanding challenge for low‑latency, highly available infrastructure. The studio needed worldwide datacenter coverage, the ability to support hundreds of thousands of concurrent matches and millions of players, frequent quarterly updates, and a way to deploy cross‑platform releases without managing complex server fleets.

Ubisoft moved Siege to Microsoft Azure—using Azure compute, Azure Blob Storage, Xbox Live Compute (Thunderhead), Azure Autoscale and Microsoft’s global network—so it could elastically scale to roughly 3 million players a day and hundreds of thousands of concurrent games. The cloud setup enabled a single cross‑platform development effort, faster feature deployment and testing, reduced operational overhead, and consistently low‑latency play, letting Ubisoft focus on game innovation instead of infrastructure.
