Last August, Dealer.com deployed a new site configuration management system based on MongoDB. We have been running this system in our live production... environment for a little over a year now and have continued to learn and refine our solution. This session will look at our experiences with MongoDB. We will start with the process we used to select MongoDB, the project's lifecycle up until the live deployment, and then what we have learned and changed over the last year. We will also take a look at what our plans are moving forward, and some other places that we have deployed MongoDB within our organization. To give an idea of scale, our current system supports configuration files for over 15,000 customer sites with thousands of revisions per site and an on-disk size of almost 200GB.
