Document Summary
Cloud systems are built on the foundation of service-oriented architecture (soa) Their inputs and outputs are specified by interfaces. Applications and business processes are built around these small, independent units. Allows interoperability & service reuse regardless of the applications, developers, involved parties or their locations. Mechanisms for applications to communicate over the. Platform independent (based on xml or json) Once an enterprise adopts soa & web services as standard, it becomes much easier to: Or use other components available via the cloud. Cloud migration is the process of moving applications or data to the cloud: Machine replication: making a copy of your existing system in the cloud. Physical to virtual (p2v): separates applications into components for easy virtualization. Works well with cloud design, requires extensive testing. The standard cloud options provide different combinations of hardware & software. These labels are just umbrella categories and encompass substantial variation: With iaas, you just get the hardware (servers):
