Just got back from Innovate 2010 and I encourage you to view the Keynotes; they will fire you up on innovation, the future, systems of systems and the future-- fer sure!
Take a look at the current IBM System Magazine to learn, among other things, how tape is far from dead -- 29.5 B bits per square inch demonstrated (44x today's capacity)??
The mainframe mag, zJournal, is now at the mainframezone, and the current issue has an article on mashups and Web 2.0 with the mainframe. (have you looked at CICS support for PHP?)
...and IBM has demonstrated a Graphene transistor based chip at 100Ghz -- as in single layer of carbon atoms exceeding cut off frequencies of silicon chips with the same gate length, is getting involved in more auto systems with Daimler, and there is a nice retrospective on Disney and IBM (with videos!) here.
So, I ran across a couple of interesting articles recently that, as a architect working with large systems and large enterprises made me stop and think.
First, in the Financial Times from June 8, a nice bit of thought on outsourcing, governance, and a reminder how key tech is and the importance of managing technology correctly!
Secondly, in the current issue of Strategic Finance (oops, sorry the specific article is for IMA members only it seems..) a good discussion on how to handle Idle Capacity Costs (pg 55). Without going into the detail, the point is execs at your enterprise are looking at these things.
And... what system helps manage resources to minimize excess capacity, maximize utilization?
... and oh by the way have you looked at moving to or consolidated non-System z systems on z lately?
Or would rather wait for your manager to ask why not?
