Review on Service Availability : A Geo-redundancy feature of Cloud based Applications

Abstract

Cloud computing is a fairly new concept which provides computing services with variety of advantage (more suitable utilization, reasonably priced and scalability). Cloud computing offers the desired facility/service of an aggregated pool of resources as a utility to user over the internet. If anyone would like to start taking advantage of cloud services there is a considerable shift of these kinds of resources into the cloud. Essentially the most important areas of cloud computing for users is overall performance and availability. However, critical application have most important concerns about the availability of their services in the Cloud. Conventionally the availability of these has been limited to local installations of hardware and software resources. On the other hand in cloud computing availability indicate the uptime of a service or system, a network, server and equipment (hardware and software) that are used to provide service. Completely satisfied cloud user’ requirements that clarify the quality of service. In this paper we focus on geo-redundancy and availability of the service in cloud environment. As well as covering the different concepts of geo redundancy, availability, issue and the highly effective benefits for the users.
