Rackspace is now offering hosted versions of the MongoDB data store, using MongoDB management technologies it acquired from its purchase of ObjectRocket in February. It also has contracted with 10gen, the company shepherding the open source MongoDB, to provide advanced support for the service. ObjectRocket created a platform specifically for running MongoDB in hosted, or cloud, services, said Matt Asay, 10gen's vice president of corporate strategy. The new service will be "one really good way to pave the path to a successful MongoDB experience," he said.
