Life full of -aaS (a.k.a. The list of -aaS.)

  • submit to reddit
We once have discussed on the topic of xOA (-Oriented Architecture), where we found how many "oriented architectures" have been researched, discussed, merged, or even made up. The same has been happening how on aaS (as-a-Service). Though -as-a-Service started with cloud offerings, now we can see, it is often used as a buzz word in other domains too, to grab some popularity and attention. I have listed down a few that I have found over the net. Please note some of the below aaS may even sound childish or made-up terms. I am not responsible for that.. ;)

1) AaaS - Analytics as a Service
On demand analytics services. Web-based analytics applications.

2) BaaS - Business as a Service Easily "virtualize" your business.

When an online fraudulent activity such as trojans is provided as a service.

A service provision model for hardware that is defined differently in managed services and grid computing contexts.

9) IaaS - Infrastructure as a Service

24) XaaS - Anything as a Service. Mostly used as an umbrella term (xaaS) to refer to all the -as a Service terminology used.

25) YaaS - You-as-a-Service
26) ZaaS - Zebra as a Service 

Feel free to provide reference to any other as-a-Service of the form xaaS that I may have missed in this list, as a comment below. I have come up with this list using the help of Google. So if your aaS is far below in the Google's ranking, most probably I would have missed it. Moreover you can find many similar lists of aaS online. I have found one myself before. However most of them are outdated lists and doesn't contain the new emerging or made-up xaaS acronyms or terminology.
