The document discusses the relationship between service-oriented architecture (SOA), cloud computing, and enterprise architecture. It suggests that cloud computing can be viewed as an extension of SOA that delivers resources via the cloud. It provides examples of different cloud computing services and discusses factors to consider when determining which services, data, and processes are suitable for the cloud versus on-premise systems. The document also provides guidance on how to integrate cloud resources within an enterprise's existing architecture.
