Data Sharing for Cloud Computing Platforms Cloud computing platforms consist of a set of reliable services that are run in the cloud. Typically, consumer applications use software development kits (SDKs) provided by the computing platform services to store, update, and retrieve instances of data in the cloud. Services provided by the cloudcomputing platform, expose different data modeling paradigms that consumer applications use to interact with the cloud. The service-specific data modeling paradigms and SDKs increase the complexity of data sharing between consumer applications that interact with the different services of thecloud computing platform. To make matters more complicated, it’s not uncommon in an enterprise to find different groups using different cloud computing platforms. In this paper, we will describe a set of abstractions that can be used to abstract different computing platforms. The abstractions not only abstract the computing platform, but also enable the data discovery and sharing between applications. We will further show that these abstractions do not add substantial latency on the performance of thecomputing platform.
