Elastic as the cloud, Cloudonix extends beyond the realms of traditional telecom thinking. Regardless how big your application may be, Cloudonix is capable of scaling up, by factors of up to 20 times its current size, within minutes. 


Cloudonix isn’t bound to the traditional carrier world, as such, it is not bound by its limiting business models. Per minute, per DID number, per device – these models are obsolete and redundant. Cloudonix’s business model is simple and predictable. 


Creating a service or application isn’t easy, it requires great attention and much investment. Cloudonix takes much of the complexity, of creating RTC applications or services, completely out of the game. Providing a ‘shrink-wrapped’ thinking methodology for product/service development.


Developers are the modern days’ wizards and knights. Masters of the keyboard and warriors of the cloud. Cloudonix enables these seasoned experts with new tools, enabling them to move faster, further and most importantly, in a way that makes to them – by developers, for developers.
