Best platform for Webhosting, mobile app development in iOS and android

[riyasnr007]

Hello All,

Please forgive me if Im asking this question in wrong place.

We have a new start up company, we need to have a good web hosting which should able to handle high band width, same content is going in to iOS and android apps, so need a common platform for all these
1) updating/uploading to the website
2) develop iOS app
3) android App

since the work going in to all these three sets are going to be same, is there any platform we can use to reduce the re work?

is it good to use Google App engine?

Thanks,
Rix
