Well, I just attended the Pulse general session. It's always interesting and educational, since it's here that you get a feel for the tone and perspective of what's happening technology and business wise.
There are some clear themes that I'm sure will be repeated often at the show. The first one is, of course, cloud. Cloud, and the support of cloud, will continue to be a dominant theme. Along with SaaS (software as a service). Look for much more to emerge from this paradigm.
Other buzz words to be aware of? Mobile is one. Mobile will be a pervasive them going forward, as is Open. There has been a big emphasis on IBM adhering to open standards.
From a specific technology perspective, what does this mean? A couple things were mentioned. One was Bluemix (a development environment based on open standards), and another was IBM's acquisition of Cloudant (a cloud based database service).
Bluemix sounds interesting, and if you want to learn more go to: www.bluemix.net
