IBM on Monday is expected to unveil Blue Insight, a massive business analytics cloud that will hold more than a petabyte of data. This internal cloud computing environment will be the basis for future external services.

Internally, IBM's effort is dubbed Blue Insight, a business analytics cloud that will give 200,000 employees access to key corporate data around the world. Blue Insight will suck in data from 100 different data stores and warehouses. The data will then be dished out to salespeople and developers.

According to IBM, Blue Insight is a showcase of the "eat your own dog food" mantra. The system is built using Cognos, IBM's business intelligence software, and hardware systems such as System Z, the company's mainframe.
