This week we’ve seen a couple of major IT vendors dive further into big data, along with updates from two providers that managed to introduce analytics to the cloud, and vice versa.

IBM acquired Tealeaf, which makes solutions for consumer-facing retailers that need to spot consumer trends in time to keep their merchandising efforts on par with that of their peers.  This is nothing new for IBM, which is steadily building out its range of big data tools and services, and Tealeaf certainly isn’t Big Blue’s first big data buy in the past few months, but the deal does mark an extended commitment on behalf of the latter to keep up with the competition. IBM is doing the same thing in the cloud, which you can read about in our other roundup.

The second analytics-related acquisition this week was made by Cisco. The networking giant is finalizing an agreement to purchase Truviso, a firm that specializes in identifying areas within networking environments that can be improved upon.

Jive mixed big data with yet another field this week, when it updated its enterprise social network and introduced a trial for prospective customers. Among the several big improvements lies Jive Edge, a search engine (with the emphasis placed on the engine portion) that powers tool execs can use to assess the way their workers interact within the internal platform. The need to identify consumer demands has been around for a while, and Jive is taking that to a whole other level by turning this concept inside out.

It can be said that business intelligence firm Jaspersoft has done something not entirely dissimilar this past week. The developer said that it’s bringing analytics to VMware’s Cloud Foundry PaaS by releasing a re-written, open-source version of its propriety BI suite.
