One of the first mobile instant messaging communities offered by Tjat was ICQ Mobile Chat , and in 2006, the decision to deploy a fully hosted, browser based service based on cloud computing had to be defended against the conventional wisdom of dedicated clients for mobile VAS deployment.

With the emergence of Java during the 1990s, a debate on the future of applications began. Would software shift from a device centric approach of native programs on the local PC or mobile device (like Microsoft Office) toward a web-centric services and applications accessed through universal clients like a browser (like Google Docs or Tjat deployed, browser based ICQ Mobile Chat).

Java, Developed by Sun Microsystems, is a cross-platform environment used by that many web-based applications, albeit “in the cloud” — on central servers — with the User Interface handled locally by browsers or other Universal clients – Cloud Computing. One big benefit of cloud-based, web-centric applications is that users can access the apps and their personal data from any computer using a browser.

Tjat is using Cloud computing principles to bring web messaging such as ICQ Mobile Chat to the masses, without the need for costly development cycles of dedicated, device specific clients, enabling huge savings in the development process, passing on the benefits and flexability to MNOs and their subscribers.
