Mobile client - web app secure communication

[jaenswart]

Hi guys,

In your opinion, what is the best solution that is also secure to enable integration and communication between a fat mobile client and a web application, like for instance a grails web app?

Later this could be extended to a normal desktop app that needs to communicate with the webapp.

Would one use webservices exclusively for all communication or what else is there?

I would like to here your opinion?

The easiest thing is just to do your communication, whether it is WS or REST, over HTTPS.
