In an industry already littered with three-letter acronyms, we have yet another to get used to. This time, however, it’s a three-letter “extension” to previously solitary technologies.

That acronym is “aaS,” also written “as a service.”

The core methodology behind cloud computing hinges on the service-based delivery of technology for application processing, data analytics, data storage, and other ancillary functions. Within the cloud, we tier infrastructure as a service (IaaS) below platform as a service (PaaS) and place software as a service (SaaS) on top.

But we can go further with “aaS” than this core trinity.
