8. Technology

1. Multi-User WebOS is built for:

   1. Maximum Performance

   2. High security

   3. High Scalability

   4. High Compatibility

      Multi-User WebOS is built on web technologies such as PERL, HTML5, PHP, Open Source GUI, Open Source VDI and JavaScript. It delivers the outstanding performance because of its kernel is compiled in C++ for more efficiency. WebOS runs on fully clustered architecture and contains an open source framework to ensure that all operations is secure.

      • In Technical View: WebOS System structure

        WebOS system is divided into multiple components that will run on JavaScript, HTML5 &PHP.

        Apps is divided into two parts:

        1. First part runs on the client desktop system in a Web browser

        2. Second part is interpreted by the PHP interpreter (Webserver).

        The app will run on client side with the user interface using the PHP & JavaScript.

      • Performance View:

        The adoption of workspace in virtualization is made, a question that often arises about the performance issue. Connecting the web apps from the private cloud is a very good option, but another question arises that "Is it as smooth as a traditional client-server for the user model?

        Firstly, most of the frontend activities takes place within the local web browser: moving mouse, minimizing or maximizing a window, typing etc. The users will experience no latency issues in the most repetitive tasks in daily routine.

        Secondly, Multi-User WebOS architecture separates the different main tasks, the possibility of dedicating the separate servers in a current cloud environment if the load becomes more intense.

        Finally, the Multi-User WebOS kernel is compiled in C++ for maximizing the speed and performance of Web Operating System. Server Requests are answered in 10 ms on average.

      • RIA Framework for WebOS:

        Multi-User WebOS in Cloud Environment RIA framework is a great resource to have the new custom applications be developed to cover the organization needs and to leverage the native functions on the system.

        The Multi-user WebOS in Cloud requires programming languages such as HTML5, PHP, Perl and JavaScript for app development. GUI window for Web OS developed using high-level JavaScript libraries. For developing GUIs java swing etc. web toolkits are used. It also uses communication among libraries to exchange the messages and AJAX Requests to run the PHP functions defined in application.

        Applications in WebOS is an independent component that deploys the WebOS APIs by using the RIA development environment in Linux or Windows OS.

      • Security:

        The WebOS appliance has the host protection, with the help of zero outside dependencies. For

        this reason, for managing the security solution for channels via SSL and SSH. The configuration of the custom SSL certificates and backup management system points are created. Integration of firewalls in the cloud web server, security script modules, by enabling SSH and installing the SSL 256bit provides the extended protection to the Multi-User WebOS in Cloud Environment.

      • Functionalities:

        Multi-User Web OS in Cloud functions like Virtual Desktop Management, Web Desktop Management, user management, file sharing services, real-time alerts, real-time notifications, real-time instant chats, forums, communities, database management, Moderator Management, Application Installation management, User Profile Management etc. Allows the multi-user simultaneously in the same session time and no downtimes in terms of bandwidth. Allows 'n' number of users. File synchronization is made easy for instant and faster access to the web desktop.

        Multi-User WebOS detects the device type automatically when the user is logged-in, pushing the web desktop interface that best fits both the user interfce and the device.

2. Characteristics:

• Multi-User WebOS with multiple applications can be accessed at once by the Muti-Users in the same single session.

• Multi-User webOS can display the list of apps such as calendars, mailboxes, browsers, office tools etc. can be viewed in the single common layer.

• Combined Messaging exchange is clearly possible in WebOS. It lets you to view all the conversations with the same person in a single screen in a web chat console, chat can be initiated among the users in an organization.

• Multi-User WebOS is also compatible with low bandwidth network connectivity.

• WebOS include an integrated Web browser that is compatible with the video formats like .AVI,

  .MPEG, MP4, Flash etc.

• Compatible with Android device, Windows Mobile Device, Netbooks, Notebooks, Personal Desktops etc.

1. Conclusion
