The PaaS on PaaS marketure has me confused. The ecosystem surrounding Cloud Foundry demonstrates how PaaS, the middle level between SaaS and IaaS is actually a multi-layered market space. A way to unwind the recursive relationship between Cloud Foundry and ecosystem partners is to first start calling the technology a ‘cloud-enabled platform’, and limit PaaS as an instantiation of the cloud-enabled platform delivered as a service. The CloudFoundry ecosystem partners (e.g. AppFog, Stackato, Uhuru, Tier3) seem to be competing on ease of use enhancements, bundled technology (e.g. language support, cache support, database support), or managed hosting.
Platform as a Service resides within the space between Software as a Service (SaaS) and Infrastructure as a Service (IaaS).

“Let’s make this stuff as simple as possible, articulating complexity does much to build barriers to cloud adoption….”
