The main advantage of that ExtJS has over other frameworks is its component-oriented model which leads to a consistent and easy to use API to build widget-based interfaces. It also now features integrated touch sensitive web apps using HTML5 which makes it an even stronger Ajax tools and Portal framework
The integration that we have done for the engineering company is going to be key to enabling data access for storage clouds when users sign into the Portal. Clouds such as S3, and internal storage clouds, will be mapped into the on-premise SMEStorage Cloud Gateway appliance. Authentication is being handled by integration with an internal identity management server so that single sign-on can be accomplished.
The real power of the on-premise appliance and the rich API is that not only can users use the Portal to access files, they can also use the white label version of the Windows / Mac / Linux desktop tools , and also the Android, BlackBerry, iPhone, IPad mobile clients.
