The Structure 09 panel of successful Cloud practitioners (all the right places and people) had some real insight. Last year the key takeaway was scalability — if you didn't know how you were going to scale it would certainly kill you if you started to succeed. The wisdom this year was at a higher level, and the first part might be summarized by (a) think at the system level, (b) think probabilistically (bad things happen rarely but frequency with large numbers) and (c) it's really useful to own your own stack and be able to make everything work well together (this all speaks well to the Cisco UCS value proposition but that's a longer story). The second part was that humans are still the key to effective solutions and the ultimate cause of most problems (that was the Google perspective after 10 years and maniacal focus on tools and automation!). The broader wisdom at the meeting was that it really is mostly about virtualization (as a key enabler of pre-existing concepts) and utility computing, and it all makes sense if we stop elevating "Cloud" to something new and magical (as we here at IRG have concluded as well).
