Presenting at the Dutch VMUG 2010!

This year the dutch VMUG event (see www.vmug.nl) is surely going to be a great success. Again! For the first time I’ll be there as a blogger. Even better, last week I had a nice discussion with someone at IBM. They welcomed me to deliver 20-30 minutes of their presentation at the VMUG2010 event!

So be sure to visit the VMUG 2010 event, and especially the 15:50 – 16:50 session “Van Virtualisatie tot Cloud Computing: portfolio en praktijk” because I’ll be presenting there, and it is going to be really interesting too! Read the rest of this entry »
