Abstract
Innovations are necessary to ride the inevitable tide of change. Most of enterprises are striving to reduce their computing cost through the means of virtualization. This demand of reducing the computing cost has led to the innovation of Cloud Computing. Cloud Computing offers better computing through improved utilization and reduced administration and infrastructure costs. Cloud Computing is the sum of Software as a Service (SaaS) and Utility Computing.
Cloud Computing is still at its infant stage and a very new technology for the enterprises. Therefore, most of the enterprises are not very confident to adopt it. This research paper tackles this issue for enterprises in terms of cost and security. In this paper I discuss the benefits and drawbacks an enterprise can have while they adopt Cloud Computing in terms of Cost and Security.
In the end, concluding that Cloud Computing is better for medium and small sized enterprises as compared to large enterprises in terms of both cost and data security.

A Review On Issues And Challenges Of Cloud Computing

Abstract
users over the web on rental basis. cloud computing is being referred to the accessing and configuring and accessing the online applications. There are some technologies being used for the general understanding of the cloud computing they are: utility computing, virtualization, SOA, grid computing. It provides an advanced virtual space for organizations to deploy their applications or run their operations, In this paper the issues and the challenges that is being faced by the cloud service providers are being discussed.
Keywords: cloud computing, IAAS, PAAS, SAAS, virtualization, security, privacy, reliability.

عنوان فارسی مقاله: مروری بر مسائل و چالش های رایانش ابری

رایانش ابری سرویسی است که به کاربران سراسر وب به صورت اجاره ای ارائه می شود. رایانش ابری به دسترسی و پیکربندی و دسترسی به کاربرد های آنلاین ارجاع داده می شود. تکنولوژی هایی که برای فهم عمومی رایانش ابری استفاده شده اند، عبارتند از: ابزار محاسبات، مجازی سازی SOA، محاسبات شبکه ای. این تکنولوژی یک فضای مجازی پیشرفته برای سازمان ها فراهم می کند که کاربرد های خود را گسترش دهند، یا عملیات خود را اجرا کنند، در این مقاله این مسائل و چالش هایی که فراهم کنندگان این خدمات با آن روبرو هستند، مورد بحث قرار گرفته است.

کلمات کلیدی : رایانش ابری، IAAS، PAAS، SAAS، مجازی سازی، امنیت، حریم خصوصی، قابلیت اطمینان.
