Jitterbit, the open source house that has taken on large-scale enterprise-grade data and application integration - problems like connecting on-premise and cloud applications and data - is pushing on to Jitterbit 3.0, a major release of its solution.

The new version, when it gets here - it's in beta right now - although some beta sites are reportedly already in production - will support high-volume transactions, expand connectivity options, and add new management tools and features for multi-user environments.

Jitterbit claims adoption by 5,000 organizations because of its out-of-the-box integration and drag-and-drop "no coding" approach. But only 100 of them pay for it including places like NASA, BP, Dow Jones and Continental Airlines.

It's supposed to cut project delivery time by up to 80% over proprietary alternatives like Informatica or TIBCO.

The company says that 65% of customers are integrating cloud computing services with existing infrastructure or other cloud services.

It can, say, take, SAP, Oracle and PeopleSoft data and move it to Salesforce.com, Google Docs, Oracle's CRM On Demand and Netsuite.

Jitterbit 3 lets multiple users download and work on a project simultaneously. All projects can be managed from a single screen and there's supposed to be robust backup and restore available now.

There are Community, Enterprise and Enterprise MX editions. Each has more functionality than the other. The new version is supposed to GA this summer. Right now there's a 3.0 Community beta and an MX beta available on a 30-day free trial.

Jitterbit got started in 2005, put its first product out in 2006, and saw no reason to take in venture capital.

The only creature it says it can't work with is that old behemoth, the IBM mainframe. It can integrate all the modern systems that use modern protocols, Web Services and open standards. It partners with Intel, Red Hat, Salesforce.com and Netsuite.
