Cloud service providers store data all over the globe, and are constantly moving that data from one datacenter to the next for reasons as wide-ranging as cost considerations and redundancy requirements. Does this mean that the requirements outlined in varying data residency laws and privacy regulations are directly at odds with how cloud computing works?
The question is an especially delicate one when the cloud service provider stores and processes data in a jurisdiction that is perceived to have far less stringent privacy and data protection requirements – or may allow government agencies far broader data subpoena powers. Since the cloud computing model relies on distributed infrastructure to generate cost and flexibility benefits for customers, building a datacenter in each data residency jurisdiction quickly becomes cost-prohibitive. And, applying a set of constraints to the movement of data introduces an additional layer of complexity that further erodes the value proposition of cloud computing for customers.
