Expert Texture » Cloud Services Continuum
Everyone is talking about cloud services and much of the conversation centers on understanding them and how they are changing the landscape. Of course, cloud services are not one thing. I find it helpful to think about them as parts of a continuum. This seems useful regardless of the technical level of the people with whom I’m speaking. imageThe diagram to the right shows this continuum from infrastructure to platform to software. Brief definitions of these parts are: * Infrastructure includes provisioning of hardware or virtual computers on which one generally has control over the OS; therefore allowing the execution of arbitrary software. * Platform indicates a higher-level environment for which developers write custom applications. Generally the developer is accepting some restrictions on the type of software they can write in exchange for built-in application scalability. * Software (as a Service) indicates special-purpose software made available through the Internet.
