As I catch up with my blog feeds after having wrongly configured Outlook, which left me without updates for more than two weeks, I came across this great post by Robert of Digipede fame. Great little summary!
“The 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.”
