The emergence of platform-as-a-service (PaaS) offerings as a foundation to build applications in a way that abstracts traditional middleware is proving to be a boon for developers in the age of the cloud. The challenge is that there is no such thing as a single cloud. The cloud actually consists of a mix of programmable platforms that lie both inside and out of the traditional enterprise. Apprenda wants to make it easier to invoke those cloud resources with the inclusion of an API that allows developers to dynamically scale resources in response to user traffic demands or a specific policy requirement within the PaaS environment.
When it comes to mobile computing most organizations are relying on applications that are running on a number of devices that remotely access data via an API. The folks at Usablenet are leveraging RESTful APIs to make the case for the exact opposite scenario.
