Cloud-Connected Mobile Apps

Today, many mobile apps are connected to one or more Web services that provide valuable and interesting data. When designing and developing such apps, the easiest approach to take is to make direct REST API calls to those services and then process the response in the client. However, this approach has a number of drawbacks. For one, every network call and every bit of client-side processing consumes precious battery power and bandwidth. Furthermore, extensive client-side processing can take a while to perform, especially on lower-end hardware, making the app less responsive. And different Web services might impose throttling limitations, which means that a purely client-side solution will not readily scale to a larger number of users.
