All the resources virtually pooled in the Cloud are offered to the customers as a service on demand basis. Cloud computing is Internet based development and use of Information/computer technology whereby dynamically scalable and often computing resources are provided as a service through the Internet. Users need not have knowledge of expertise in, or control over the technology infrastructure in the cloud that supports them. This paper presents the various services offered by the Cloud Computing. The services of the cloud computing PaaS, SaaS and IaaS are important basic services, along which some other services of the cloud computing are also presented. Keywords: Cloud Computing, pay- for-use, virtual resource, Data Centers, PaaS, SaaS, Iass. I. INTRODUCTION The definition of the Cloud Computing is broad enough to cover everything such as web search and photo sharing to social networking etc. Perhaps the key point is simply that cloud computing resources should be accessible by the customers/end users anytime, anywhere, and from any platform over internet on pay-for-use basis. Broadly, the cloud can be described as on- demand computing, fix anyone with a network connection. Access to applications and data anywhere, anytime from any device is the potential outcome. The cloud refers to wide – area networks, generally the intent from which remote computing resources are shared as shown in the Fig 1.1. The cloud reduces costs and complexity and provides scalability. The biggest advantage that the cloud brings is to reduce costs and improve efficiency. An institution can rely on the ‘pay-as-you-go’ characteristic of the three pillars of cloud: PaaS and Saas. Ease of maintenance increase efficiency as the pain of maintaining the software is now shifted to the cloud service provider.
