VMware: All content tagged as VMware in NoSQL databases and polyglot persistence
Serengeti is an open source project initiated by VMware to enable the rapid deployment of an Apache Hadoop cluster (HDFS, MapReduce, Pig, Hive, ..) on a virtual platform.
Serengeti 0.5 currently supports vSphere, with the ability to support other platforms. The project is at an early stage, and is endorsed by all major Hadoop distributions including Cloudera, Greenplum, Hortonworks and MapR.
The Hadoop wiki has a page dedicated to running Hadoop in a virtual environment. And there’s also the recent post by Steve Loughran about pros and cons of Hadoop in the cloud and a paper authored by VMWare about virtualizing Apache Hadoop (pdf).

The workshop takes you through creating a Sinatra application using sample code from here . Once the Sinatra application which leverages Twitter is working, the workshop then takes you through adding Redis to your application. Finally the workshop ends after taking you through scaling your application instances up and then back down.
Only 15 minutes to get it up and running:
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.
