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.”
