Introduction

If you need information from data that is stored on a remote system, and you do not want to move a copy of the data to the local system, then you can benefit from combining compute services and data transfer services. Reasons for not moving a copy of the data could include:

the amount of data is too large.
the data is frequently updated.
you want to avoid data duplication.

Regardless of the motivation for reducing the amount of data that is transferred, incorporating compute services will achieve your goal. As Combined Compute and Data Transfer Services Processing Model illustrates, compute services enable you to format and pre-process data into a subset or a summarized form on the remote system, prior to transferring the subsequent smaller amount of data to the local platform. This balances the use of CPU cycles between the local and remote systems and minimizes the amount of data contributing to network traffic.
