Web Operating System: “A software platform that interacts with the user through a web browser and does not depend on any particular local operating system.”

Your own sub headline

Introduction

Primary Interface = Browser. Browser will conduct OS “functions”

File Access Init Preferences

Not just a service but a platform. Open Source-Open API Truly “Write Once – Run Anywhere”.

WebOS gained popularity in 1999, WebOS Inc., was founded by Shervin Pishevar and Drew Morris

WebOS acquired WebOS.org, created by a young Swedish programmer, Fredrik Malmer, created the first online desktop environment

WebOS was covered by many media outlets such as the Wall Street Journal, financial Times, LA Times, Power lunch on CNBC, Fox News and CNN and helped spread the WebOS meme further

A Web OS behaves like a desktop OS

How it WorksWhen a person chooses to run a certain application, his or her computer sends a request to the system's control node -- a special server that acts as a system administrator

The control node interprets the request and connects the user's client to the appropriate application server or database

Web operating systems can also make it easier to share data between a Mac computer and a PC

register an account and login to Web OS web site You OS www.youos.com it is very similar to other OS we have used

How it Works continue…

Security & AuthenticationSECURITY

Step 1: users transfer some portion of their access rights to webOS server when attempting to access a remote resource

Step 2: WebOS servers communicate using SSL

Step 3: The remote server checks if the proper credentials are held in local ACL’s

Web Security Model

AUTHENTICATION

Types of authentication: PIN / Password

Max number of failed password attempts

Auto lock: yes

Remote wipe

…As per 2010 statistics

There are two main technologies that are thoroughly utilized when it comes to the creation of a Web OS: Adobe Flash and Asynchronous JavaScript and XML (AJAX)

AJAX - Highly touted by Google (Calendar & Gmail services)

Flash – More than 98% of all machines connected to internet have a flash player installed

The widespread familiarity with these technologies is one of the primary reasons why there are so many implementations of them

Applications

occupies little hard disk space

more bandwidth is needed for multiple programs to run simultaneously

can be obtained at any OS with web browser

easy to be hacked

occupy small CPU resources

can not be obtained offline

can not program on the local hardware so USB disk and CDROM can not be used.

Short Comings

Extending server functionality onto client machines allows for more flexible implementation of name resolution, load balancing, and fault tolerance

Google: Gmail -outlook, Google resource manger may also be developed to Web OS

Web OS will take more and more important role in the futureMore and more applications will be web OS based

Simplifying the implementation of a number of wide area applications

Facebook platform , Facebook open api, Facebook application maybe developed to Web OS
