Copyright © 2011, Introduction Massively Multiplayer Online Games (MMOGs) are attracting millions of players from all over the world and become an important part of personal entertainments. How to allocate cloud resources (i.e. virtual machines) efficiently so as to meet player requirements and to efficiently utilize cloud resources is a key issue for cloud computing service providers.
Copyright © 2011, Introduction We propose a resource allocation for MMOG based on AFK players in the cloud –Reduces the number of VMs used in each region –Better scalability
