As data has become more vital to core business functions, it's also become more decentralized. For developers facing integration challenges, using drivers for integration represents a logical step-up when seeking to simplify architectural complexity and build connected applications more quickly.
Google Cloud Platform is positioning itself as a major player to help mobile developers get off the block fast. While the platform was complete in terms of its Compute Engine (IaaS), App Engine (PaaS) and cloud services (Storage, Big Query, etc), developers still had to do the work of connecting the pieces. If you were a mobile developer who wanted a quick starter application in the Google cloud, you had to figure out the pieces. Similarly, if you were looking to expose your app engine applications as a bunch of REST-based services that would scale to heavy loads and work across multiple mobile devices, you had to work on your application to do so.
