A New MMOG Framework On Cloud Computing Environment

1. A New MMOG Framework On Cloud Computing Environment 張晏誌

2. Outline • Introduction • Motivation • System Architecture • Comparison • Summary

3. Introduction • Client-Server Architecture • The most popular architecture of MMOGs. • Centralized management • Satisfies data consistency • Keep games fair • Feasible to charge • Easier to find friends or contact with strangers • It has drawbacks • High cost to achieve good performance • Not scalable • Fat client

4. Introduction(cont) • Peer-to-Peer Architecture • Another architecture of online games • Distribute framework • More scalable • No performance issue to game operator • It also has drawbacks • Fat client • Unfeasible to charge

5. Motivation • To provide MMOG service in cloud computing environment. • Take the advantages of cloud computing. • Allocate resources by each player(or a tiny group of players). • To reduce network and VM migration overhead.

6. System Architecture

7. System Architecture(cont) • Isolate the resources that every player have into a single VM instance. • Also apply the same change to region server. • Avatar server is placed with its region server, to reduce network traffic. • Use exist works about load prediction (neural network approach or SVM approach…etc.) to achieve more effective resource allocation. • When a player was logged out, the player’s VM was stored as a VM image.

8. Comparison

9. Summary • Inspired by PaaS virtual desktop, use the similar concept to operate a MMOG service. • This framework can apply to any exist IaaS cloud service. • Satisfies the five characteristics of cloud computing.
