VMWare’s Cloud Foundry has the potential to become the preferred PaaS solution. It bundles together a set of services that it took years for other PaaS providers (Google App Engine, Microsoft Azure) to offer. And it seems that Cloud Foundry has much less (or none at all) vendor lock in.
From a storage perspective, Cloud Foundry is encouraging polyglot persistence right from the start offering access to a relational database (MySQL), a super-fast smart key-value store (Redis), and a popular document database (MongoDB). The only bit missing is a graph database.
I think the first graph database to get there will see an immediate bump in its adoption.
