Agenda

This session, led by the Technical Director of Ragnarok Origin 3, explores the scalable architecture of a large-scale MMORPG on Tencent Cloud. It traces the evolution from a single-server setup to a horizontally scalable, cross-server architecture, detailing how the centralized AvatarService ensures seamless player state continuity during dynamic migration. The talk also covers the intelligent, Kubernetes-based auto-scaling system that automates operations, turning the complexity of supporting millions of concurrent users into stable, manageable infrastructure. Attendees will learn key design principles and cloud-native practices for modern MMO server architecture.

Takeaway

Attendees learn a concrete architecture pattern for million-PCU MMOs on cloud: how to model avatar migration across scenes, centralize player state without killing performance, and build a telemetry-driven elastic scaling loop on Kubernetes that survives real launch-day traffic.

Intended Audience

This session primarily targets server engineers and technical leaders working on online games, as well as anyone interested in MMO backend technology. Attendees are expected to have a basic understanding of the client–server networking model.
