Decoding the cloud

摘要

Unfortunately, data security and regulatory compliance requirements do not evaporate in the public cloud. The challenge of controlling access to sensitive information remains the same. In response, three approaches have emerged: enterprise encryption services, cloud service provider encryption services, and encryption gateways. Choosing the right one depends on the type of cloud delivery model involved - software -as-a-service (SaaS) or infrastructure-as-a-service (IaaS) - and the mandates that govern the data being placed in the cloud.
