ابر خصوصی
ابر خصوصی در مرکز داده موسسه داخلی سازمان راه اندازی می شود. در ابر خصوصی، منابع مقیاس پذیر و کاربردهای مجازی فراهم شده توسط فروشنده ابر، باهم ادغام و برای به اشتراک گذاری و استفاده در اختیار کاربران ابر قرار داده می شوند. تفاوت ابر خصوصی و عمومی در آن است که کلیه منابع و کاربردهای ابری تحت مدیریت سازمان می باشند که شبیه به تابعیت اینترانت می باشد. کاربرد برروی ابر خصوصی مطمئن تر از ابر عمومی می باشد که دلیل این امر مواجهه داخلی مقرر شده اش می باشد. تنها سازمان و ذینفعان مقرر شده می توانند به ابر خصوصی دسترسی داشته و روی آن کار کنند.

Cloud Computing Security Issues and Challenges Kuyoro S. O. afolashadeng@gmail.com Department of Computer Science Babcock University Ilishan-Remo, 240001, Nigeria Ibikunle F. faibikunle2@yahoo.co.uk Department of Computer Science Covenant University Otta, 240001, Nigeria Awodele O. delealways@yahoo.com Department of Computer Science Babcock University Ilishan-Remo, 240001, Nigeria Abstract Cloud computing is a set of IT services that are provided to a customer over a network on a leased basis and with the ability to scale up or down their service requirements. Usually cloud computing services are delivered by a third party provider who owns the infrastructure. It advantages to mention but a few include scalability, resilience, flexibility, efficiency and outsourcing non-core activities. Cloud computing offers an innovative business model for organizations to adopt IT services without upfront investment. Despite the potential gains achieved from the cloud computing, the organizations are slow in accepting it due to security issues and challenges associated with it. Security is one of the major issues which hamper the growth of cloud. The idea of handing over important data to another company is worrisome; such that the consumers need to be vigilant in understanding the risks of data breaches in this new environment. This paper introduces a detailed analysis of the cloud computing security issues and challenges focusing on the cloud computing types and the service delivery types. Keywords: Cloud Computing, Scalability, Infrastructure, IT. 1. INTRODUCTION For years the Internet has been represented on network diagrams by a cloud symbol until 2008 when a variety of new services started to emerge that permitted computing resources to be accessed over the Internet termed cloud computing. Cloud computing encompasses activities such as the use of social networking sites and other forms of interpersonal computing; however, most of the time cloud computing is concerned with accessing online software applications, data storage and processing power. Cloud computing is a way to increase the capacity or add capabilities dynamically without investing in new infrastructure, training new personnel, or licensing new software. It extends Information Technology’s (IT) existing capabilities. In the last few years, cloud computing has grown from being a promising business concept to one of the fast growing segments of the IT industry. But as more and more information on individuals and companies are placed in the cloud, concerns are beginning to grow about just how safe an environment it is. Despite of all the hype surrounding the cloud, customers are still reluctant to deploy their business in the cloud. Security issues in cloud computing has played a major role in slowing down its acceptance, in fact security ranked first as the greatest challenge issue of cloud computing as depicted in figure 1
