If mongoDB is your thing, you’ll be pleased to know that there are three mongoDB cloud database offerings available for you to use. I just added two new ones to the Database as a Service Product Directory.
Next, if you have 30m or so, check out this video from 10gen, the company that builds mongoDB, which is a introduction to the three services in the Product Directory.
And if you’re into Ruby on Rails with mongoDB, Heroku makes it easy to tie into MongoHQ, one of these cloud database services with an add-on. Cool to see how various cloud platforms and services are integrating with one another.
