i am shyama . i am doing mtech in cse I need report on cloud gaming for my seminar presentation.

Introduction
Cloud computing is a recently developing paradigm of distributed computing. Though
it is not a new idea that emerged just recently. In 1969 [16] L. Kleinrock anticipated,
“As of now, computer networks are still in their infancy. But as they grow up and
become more sophisticated, we will probably see the spread of ’computer utilities’
which, like present electric and telephone utilities, will service individual homes and
offices across the country.” His vision was the true indication of today’s utility based
computing paradigm. One of the giant steps towards this world was taken in mid
1990s when grid computing was first coined to allow consumers to obtain computing
power on demand. The origin of cloud computing can be seen as an evolution of
grid computing technologies. The term Cloud computing was given prominence first
by Google’s CEO Eric Schmidt in late 2006 (may be he coined the term) [6]. So
the birth of cloud computing is very recent phenomena although its root belongs to
some old ideas with new business, technical and social perspectives. From the architectural
point of view cloud is naturally build on an existing grid based architecture
and uses the grid services and adds some technologies like virtualization and some
business models.
Cloud Computing Basics
Cloud computing is a paradigm of distributed computing to provide the customers
on-demand, utility based computing services. Cloud users can provide more reliable,
available and updated services to their clients in turn. Cloud itself consists
of physical machines in the data centers of cloud providers. Virtualization is provided
on top of these physical machines. These virtual machines are provided to the
cloud users. Different cloud provider provides cloud services of different abstraction
level. E.g. Amazon EC2 enables the users to handle very low level details where
Google App-Engine provides a development platform for the developers to develop
their applications. So the cloud services are divided into many types like Software
as a Service, Platform as a Service or Infrastructure as a Service. These services
are available over the Internet in the whole world where the cloud acts as the single
point of access for serving all customers. Cloud computing architecture addresses
difficulties of large scale data processing.
Cloud Stakeholders
To know why cloud computing is used let’s first concentrate on who use it. And
then we would discuss what advantages they get using cloud. There are three types
of stakeholders cloud providers, cloud users and the end users [Figure 1]. Cloud
providers provide cloud services to the cloud users. These cloud services are of
the form of utility computing i.e. the cloud users uses these services pay-as-you-go
model. The cloud users develop their product using these services and deliver the
product to the end users.
Motivation towards Cloud in recent time
Cloud computing is not a new idea but it is an evolution of some old paradigm of
distributed computing. The advent of the enthusiasm about cloud computing in
recent past is due to some recent technology trend and business models [5].
Cloud Architecture
The cloud providers actually have the physical data centers to provide virtualized
services to their users through Internet. The cloud providers often provide separation
between application and data. This scenario is shown in the Figure 2. The
underlying physical machines are generally organized in grids and they are usually
geographically distributed. Virtualization plays an important role in the cloud
scenario. The data center hosts provide the physical hardware on which virtual machines
resides. User potentially can use any OS supported by the virtual machines
used.

Cloud gaming, sometimes called gaming on demand, is a type of online gaming. Currently there are two main types of cloud gaming: cloud gaming based on video streaming and cloud gaming based on file streaming. Cloud gaming aims to provide end users frictionless and direct play-ability of games across various devices. In 2000, G-cluster demonstrated cloud gaming technology at E3. The original offering was cloud gaming service over Wi-Fi to handheld devices.[citation needed] Video game developer Crytek began research on a cloud gaming system in 2005 for Crysis, but halted development in 2007 to wait until the infrastructure and cable Internet providers were up for the task.[1] OnLive officially launched in March 2010, and its game service began in June with the sale of its OnLive microconsole. On April 2, 2015, it was announced that Sony Computer Entertainment had acquired OnLive's patents, and OnLive closed its doors. In November, SFR launched a commercial cloud gaming service on IPTV in France, powered by G-cluster technology.
