Cloud Computing

Introduction

Cloud computing, is an innovative network-based distributed computing paradigm that promises us that "we won't compute on local computers, but on centralized facilities operated by third- party compute and storage utilities". Compared to other distributed computing paradigms over the network, cloud computing has a few advantages that distinguish it from other similar paradigms. Cloud computing offers a scalable virtual Infrastructure to users and developers It gives the illusion of an unlimited resource for computation and data storage Since It allows users to start small and Increase computation or storage resources only when they need, It provides users With access to large amounts of "hardware resources" In a short time Interval Without requiring the users' fixed Investments or maintenance costs for expensive hardware.

Discussion

Cloud computing requires a new trust model that shares the security responsibility between service provider and client. The core security challenge of cloud computing is that the information owner does not control the hardware that is operating on his data. Complicating the situation is that the hardware is multi-tenant with shared resources among many users. We leverage trusted computing technology to build trust into utility cloud computing; however, existing techniques do not satisfactorily solve the problem. We define a new trust model for cloud computing and introduce three new mechanisms that provide for building trust into utility cloud computing environments and help solve the core security challenge of cloud computing (Abadi, 2009). The threat profile increases considerably for cloud computing compared to traditional IT environments. Attackers have much more access to attack exposed cloud computing services due to the open nature of cloud computing compared to the closed environment of traditional IT.

The role of information technology is spreading every day. New technologies are emerging with time, and these technologies are benefitting the corporate world and individuals. With the emergence of new technologies, companies are going towards the outsourcing of the information technology. Cloud computing is one of the technology, which is rapidly being used by companies. The "cloud computing" is a concept emerged relatively recently, but its beginnings go back a few years, especially in the technology of grid computing used for scientific computing. Cloud computing refers to the use of memory and computing capabilities of computers and servers around the world, linked by a network, such as the Internet (Yanga, 2009). Users of the cloud may well have a flexible and considerable computing power. The entire computing power and memory, as a tool provided as a service to customers by a business, is advertised by some professionals as the ultimate stage of the industrialization of data centers (Yanosky, 2008). IT outsourcing has always been one of the most popular destinations in the services segment. But amid the popularity of cloud computing to begin to displace more flexible IT services that can be provided on request for many of the technological aspects of the enterprise. It is supposed to be the new name of the IT outsourcing. Analysts consider it a best possible solution that can avoid ...
