MongoDB’s success with web and mobile developers in the start-up community is well known. The open source NoSQL database recently surpassed 4 million downloads and is in use at start-ups like Foursquare, VisibleGains, Shopcade and Gilt.

Increasingly, however, MongoDB is getting attention from developers inside larger, more “traditional” enterprises, such as MetLife. The 145 year-old insurance company announced last month that it is using MongoDB to support its new web app called The Wall. The app draws on data from over 70 data sources and provides call center reps with a more complete view of the customer.

CIO Gary Hoberman said MetLife went with MongoDB in part because it can handle multi-structured data and presents the combined data as a single customer record.

But large companies in regulated industries, such as financial services and healthcare, also need enterprise-grade management and security capabilities before they’ll adopt a new technology. And that’s a major focus for engineers at 10gen, the New York City-based company that is commercializing MongoDB for the enterprise.

“We’ve proven that Mongo is easy to get started with, easy to build an application,” said 10gen’s Kevin Hanson speaking live inside theCUBE at Strata earlier this year. “But if you’re a big company what happens if you have a big implementation? What does that look like? How do you monitor it? How do you deploy it? All the tools around it, that’s a big focus for us this year.”

Released in March, MongoDB 2.4 indeed includes a significant number of enhancements to its monitoring and security capabilities. Among them is an on-premise version of 10gen’s operational metrics monitoring application. Previously the app was only available as part of 10gen’s cloud offering. It’s an important development for 10gen if it wants to truly make inroads in the enterprise, many of which want to deploy Mongo inside their own four walls.

10gen is also smartly leveraging partners to increase Mongo’s appeal to enterprise developers. Earlier this month, 10gen and IBM announced a partnership that will open up data in DB2 and WebSphere ExtremeScale to applications built on top of MongoDB.  And Informatica included codeless MongoDB data integration capabilities in its new PowerCenter Big Data Edition, also released earlier this month.

Judging by the speaker line-up at tomorrow’s MongoNYC conference, 10gen’s efforts to target the enterprise are working. Speakers include representatives from MetLife, Goldman Sachs and CitiGroup.

theCUBE will also be at the event tomorrow, kicking off live coverage at 10am ET. We’ll be talking to 10gen CEO Max Schireson, 10gen engineers, plus a number of MongoDB users from WebMD and Foursquare (among others) and 10gen partners including IBM and Mortar.
