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

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

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.

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.

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.
