MBaaS (mobile back end as a service) is a fairly new product category that has largely supplanted MEAPs (mobile enterprise application platforms). Over the past two months, I've closely examined five MBaaS systems: AnyPresence, Appcelerator, FeedHenry, Kinvey, and Parse. In this article, I'll wrap up the series by summarizing all five systems, surveying their common ground and key differences, and drawing conclusions.
