Hi Folks,
the guys at IBM offer you a chance to take a look at their BIG data offering first hand. Just go to the URL below, and you'll be able to get the Quick Start Edition of Infosphere BIG Insights. You'll need to create your IBM ID to download the virtual machine, but hey that's no hassle.
It's a VMWare image, but there's an option to get the machine in OVF format so you can open it in Virtual Box for example.
Take a look, I will for sure.
