I am pleased to announce that OMG's Middleware & Related Services (MARS) Platform Task Force voted on June 23 to approve the release of the discussion paper entitled "XaaS (Anything as a Service) Glossary," prepared by members of the Cloud Working Group.
The document is free and available at https://www.omg.org/cgi-bin/doc?mars/22-06-08.pdf
The paper aims to dispel the confusion about all the phrases of the form "X as a service" that have been coming up in service descriptions, marketing literature, consultant reports, technical journals, etc. It draws a distinction between terms that designate service offerings that actually meet the criteria originally set by NIST (network-based access, elasticity, metered service, etc.) and terms that tend to misrepresent certain offerings.
Feel free to read it, use it, spread the news, and ask me questions (I was the main author and editor).
