Orient Technologies closes the NuvolaBase Division

London, September 21th 2013

NuvolaBase, the Orient Technologies division that offered OrientDB as "Database As A Service" (DaaS), announces to stop its activity. In this way Orient Technologies company will be more focused against OrientDB on development, support, consultancy and training.

All the paying clients will be hold for FREE for +6 months after the expiration of their contracts to give them the time to switch to another solution.

What about the alternatives?

We suggest to install OrientDB Open Source Graph Database on top of a Virtual Machine hosted at any Cloud Provider like AWS.
