When Aleri bought Coral8 last year, I wrote that the independent CEP (Complex Event Processing) vendors were floundering. Aleri quickly threw in the towel and sold out to Sybase, which hardly changed my opinion. StreamBase actually is persevering, but not with any kind of breakout success. Big vendors, such as Microsoft and IBM, have at least some aspirations of eventually filling the gap.
Meanwhile, Truviso — which never got much market traction in the first place — was in hiding; Roman Bukary never did keep his promise to brief me on the company’s new and improved strategy. Then Truviso had yet another management change, amidst rumors that it was repositioning away from CEP. As per a press release Truviso emailed today, that’s now official, with Truviso’s main business being something to do with web analytics.
Edit: It seems Truviso was at some point absorbed into Cisco.
