Let me introduce myself : Guillaume FORTAINE, Cloudpreneur.
First of all, I would greatly appreciate to invite you to a reading of the blog post entitled "Death of the Pure IaaS Cloud" .
On my side, I am currently exploring PaaS platforms, especially the ones that are multi-tenant .
That's why, I would like to inform you of the CompatibleOne project. To quote  :
-Provide a feature-rich, industry standard cloudware to build
applications on the cloud
-Multi-tenant platform (deployment, application execution)
-Abstraction layer allowing its utilization through high-level
services such as relational and post-relational storage, as well as
synchronous and asynchronous communication and documentation
and I would greatly appreciate to have your comments about this one,
if possible, please.
