If you wanted to get started with VMware vSphere APIs watch my UK VMware User Group session last month. Its a refresh of an older session I use to deliver. I focus less now on the SOAP based API and more on the REST based API.
Recently I was awarded the title of Distinguished Expert at Atos and now am the leader of the Automation Domain in that community. The expert community was formed to unite the experts in Atos and see if through alignment of different factions, business units, and cultures we can come up with some amazing IP. Anywho.. here is a nice video recorded to promote that Domain.
