I am a newbie on Amazon Web Service. I have a task that setup then build a web service that provide APIs to Mac OS, iOS, Android client. There are some APIs and Database need to be kept in secure. I see that AWS support multiple platform such as Java, .Net, PHP,... It also support many Database Management System. Not yet, there are 2 special SDK for Android and iOS app.
So, What should I choose (Java, .Net, PHP,...) to carry out my task? Does AWS support all webservice protocol? Does it support secure webservice?
Thanks a lot.
