ABSTRACT
Cloud computing is a technology of computing in which internet and central remote servers are provided “as a
service” to users. This paper describes cloud computing model where users access virtual shared server on
payment as per usage. Cloud Providers offer services that can be grouped into three categories termed as SaaS,
PaaS, IaaS. The paper aims to provide a means of understanding the model and exploring research investors for
complementing cloud computing technology.
1. Introduction
Cloud computing is a technology which uses the internet and central remote servers to maintain data and
applications. Cloud computing allows the users to use any applications without having to install at computer with
the help of internet connection. This technology provides efficient computing by centralizing storage, memory,
processing and bandwidth [1].
A simple example of cloud computing is Yahoo email, Gmail, or Hotmail etc. You don’t need software or a
server to use them. All a consumer would need is just an internet connection and you can start sending emails.
The server and email management software is all on the cloud and is totally managed by the cloud service
provider Yahoo, Google etc. The user gets to use the software alone and enjoy the benefits. For Example 'If you
need milk, would you buy a cow?' All the users or consumers need is to get the benefits of using the software or
hardware of the computer like sending emails etc. Just to get this benefit (milk) why should a consumer buy a
(cow) software /hardware .Cloud computing users do not require having the physical infrastructure rather they
hire the usage from the third party provider. They use the resources as a service and pay only for the resource that
they use
. Conclusion:
Cloud Computing represents one of the most significant shifts in information technology. Despite its growing
influence, concerns regarding cloud computing still needs to be explored. Cloud providers are investing their next
generation of systems to be deployed into Cloud Computing to gain the advantages of cloud participation. Many
universities, vendors and government organizations are investing in research in field of cloud computing.
