Hi. I want to make an instant messaging App with Appcelerator. Message may be a text, picture, audio or video clip. I don't know what is the best possible server side option for IM App. I tried on Google and found ACS and pubnub. I don't know ACS or pubnub supports audio and video messages ? Please recommend me best option. What server should i use for quick development of IM App ?
