Abstract: The computational world is becoming very large and complex. Cloud computing has emerged as a popular computing model to support processing large volumetric data using clusters of commodity computers. In today’s world, cloud computing has generated a lot of interest and competition in the industry. With the emergence of new cloud providers, identifying one that best suits the business needs of an enterprise is a challenging and difficult task. for to a novice or user with little knowledge about cloud computing, it is still very hard to make a reasonable choice. In this paper begins with a glimpse of cloud computing. The main aim of this paper is to focus on the various cloud vendor products and services comparison for decision making process of optimal service selection and to provide a brief comparative analysis of various cloud services. This paper also presents a table of comparison of some same products and services for some renowned cloud service providers, some pros, cons and features. finally compare with security algorithms for various cloud vendors. Keywords: Cloud Service Providers, Security Algorithms, Cloud Providers Comparisons, Cloud Products, Cloud Services.
I. INTRODUCTION Cloud computing is a completely new technique to put forward from industry circle, it is the development of parallel computing, distributed computing and grid computing, and is the combination and evolution of virtualization, utility computing [25]. Cloud computing is the outsourcing of IT communications by the use of the Internet and maintaining own hardware and software environment. Cloud computing facilitates computing assets on demand by the use of a service provider. It is there whenever you need it, as much as you need, and you pay as you go and only for what you use. The vendors provide services according to various service models for e.g. IaaS, PaaS, SaaS. Infrastructure as a Service (IaaS): This service provides the infrastructure. like, Servers, Operating Systems, Virtual Machines, Networks, and Storage on rent basis. Eg: Amazon Web Service, Microsoft Azure. Platform as a Service (PaaS): This service is used in developing, testing and maintaining of software. PaaS is same as IaaS but also provides additional tools like DBMS and BI service. Eg: Apprenda, Red Hat OpenShift. Software as a Service (SaaS): This service makes the users connect to the applications through the Internet on a subscription basis. Eg: Google Applications, Salesforce. This paper discusses various cloud Products, Services, Service providers and Security Algorithms available in cloud computing. The below figure (Fig 1) shows cloud computing structure.
