Massively multiplayer online game (MMOG).

It is estimated that 55% of internet users play multiplayer online games.

The online gaming industry alone is valued at 7 billion USD.

The most famous example is World of Warcraft.

Each game in the cloud has its own dedicated hardware, thus leading to overprovisioning of resources.

Even if the company has multiple games it will employ dedicated hardware for each of those games.

A common problem in the online gaming industry is the sharded design architecture that is currently being employed.

This sharded principle will worsen the over provisioning phenomenon

Another problem to be considered is Network latency must be low enough to have a decent gameplay experience.

Using the Spatial-locality property of the player. Using spatial locality property,three categories

can be formed1. Area of interest2. Zone of interest3. Realm of interest

Each of these will have a set of players associated with them.

P2P connections can be formed within each set. Propagation of events can be based on priority.

When a particular zone reaches a certain threshold value, we can split the zone further to maintain the Quality-of-Service (QoS).

If the zone is sparsely polulated, we can combine the zones.

Reducing the number of players in a zone reduces the number of events to be propagated.

Each zone can be hosted in a separate VM. When its time to combine or split the zones meta-data can be passed.

Internet connection:• One of the main issue with cloud gaming.• If connection becomes congested or there is a

packet loss, frame rate will drop resulting in degradation of game play
