2. Copyright © 2011, MBL@CS.NCTU Motivation To provide MMOG service in cloud computing environment. Leverage the strength of cloud computing. (Satisfies the five characteristics of cloud computing.) Allocate resources by each player(or a tiny group of players). To reduce network and VM migration overhead. 2

3. Copyright © 2011, MBL@CS.NCTU System Architecture 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. When a player was logged out, the player’s VM was stored as a VM image. 3

5. Copyright © 2011, MBL@CS.NCTU Future Work In [1], they use aura-nimbus model to form a zone that covering AOIs of players. In [2], they use clique finding algorithm for grouping players. 5

6. Copyright © 2011, MBL@CS.NCTU Future Work 6 According to above approach, we can know the relation between players. We can determine the degree of connectivity of them and allocate resources base on those information.

Run a big task in this environment, such as Word Counting task, but without Map- Reduce. Note down the execution time of the task, and compare with the result of HW2 which executed with Map-Reduce technique.
