A Comparative Study on Various Services of Web Based Operating System: a Review: Exploring the Future of Web-Based Operating Systems

Abstract

WebOS (Web based operating system) is a new form ofOperating Systems. You can use your desktop as a virtual desktop on the web,accessible via a browser, with multiple integrated built-in applications thatallow the user to easily manage and organize her data from any location.Desktop on web can be named as WEBtop. A new form of computing known as cloudcomputing can help us to design web based operating systems for future. Thispaper starts with a introduction of WebOS and its benefits . For this paper ,We have reviewed some most interesting WebOS available nowadays and tried toprovide a detailed description of their features. We have identified someparameters as a comparison criteria among them. In this paper, wedemonstrate the power of providing a common set of Operating System services towide-area applications, including mechanisms for naming, persistent storage,remote process execution, resource management, authentication, and security. Ona single machine, application developers can rely on the local operating systemto provide these abstractions. In the wide area, however, applicationdevelopers are forced to build these abstractions themselves or to do without.This ad-hoc approach often results in individual programmers implementingnon-optimal solutions, wasting both programmer effort and system resources. To address theseproblems, we are building a system, WebOS, that provides basic operatingsystems services needed to build applications that are geographicallydistributed, highly available, incrementally scalable, and dynamicallyreconfigurable. Experience with a number of applications developed under WebOSindicates that it simplifies system development and improves resourceutilization. In particular, we use WebOS to implement Rent-A-Server to providedynamic replication of overloaded Web services across the wide area in responseto client demands. Traditional reconfigurable computing platforms aredesigned to be used by a single user at a time, and are acknowledged to bedifficult to design applications for These factors limit the usefulness of suchmachines in education, where one might want to share such a machine andinitially hide some of the technical difficulties so as to explore issues ofgreater value. WebOS is a newly emerging Operating System, accessiblevia a browser, with multiple integrated built-in applications that allow theuser to easily manage and organize her/his data from any location. You can useyour desktop as a virtual desktop on the web. In the wide area, applicationdevelopers are forced to build abstractions themselves. This ad-hoc approachwastes programmer effort and system resources. To address these problems, WebOSprovides basic operating systems services needed to build applications that aregeographically distributed, highly available, incrementally scalable, anddynamically reconfiguring. This paper starts with an introduction of Webs andits benefits, but it also have some flaws related to security.
