CLOUD GAMING:FROM ON-PREMISES TO THE CLOUD
Author: M Ruthvik Mohan
Cloud gaming has been a topic of interest in the gaming industry for several years now. The concept of cloud gaming is to remotely render an interactive gaming application and stream the scenes as a video sequence back to the player over the internet. The great majority of less capable devices that only support thin clients, such as smartphones and tablets, are now included in the user base of these new gaming services, which has enormous advantages. The gaming industry has been revolutionized with the emergence of cloud gaming platforms such as OnLive and Gaikai. The $380 million purchase of Gaikai by Sony, an industrial giant in digital entertainment and consumer electronics, and the forthcoming integration of Gaikai and Sony’s Play Station 4 show that cloud gaming is beginning to move into the mainstream.

Cloud gaming has been a topic of interest in the gaming industry for several years now. The concept of cloud gaming is to remotely render an interactive gaming application and stream the scenes as a video sequence back to the player over the internet. This new paradigm of gaming services brings immense benefits by expanding the user base to the vast number of less powerful devices that support thin clients only, particularly smartphones and tablets. The gaming industry has been revolutionized with the emergence of cloud gaming platforms such as OnLive and Gaikai. The $380 million purchase of Gaikai by Sony, an industrial giant in digital entertainment and consumer electronics, and the forthcoming integration of Gaikai and Sony’s Play Station 4 show that cloud gaming is beginning to move into the mainstream.
Existing cloud gaming platforms tend to focus on private non-virtualized environments with proprietary hardware, where each user is mapped in a one-to-one fashion to a physical machine in the cloud. Modern public cloud platforms heavily rely on virtualization, which allows multiple virtual machines to share the underlying physical resources, making truly scalable play-as-you-go service possible. Despite their simplicity and ease of deployment, current cloud gaming platforms haven’t fully utilised the modern cloud’s capabilities in order to expand to extremely high scales with flexible services. However, moving games to a public cloud, such Amazon EC2, is not simple. For efficient virtual resource sharing with little overhead, the system components should be carefully planned. Modern game engines also depend on dedicated graphics processing units in addition to the general purpose CPU as the complexity of 3-D rendering rises (GPUs). While contemporary virtualization systems have virtualized GPU cards to some extent, their performance has historically been poor for the given ultrahigh memory transfer demand and the unique data flows.
