Conversations about Cloud – “What is Cloud Computing?”

Sometimes we spend so much time involved in the inner-workings of something (“inside the sausage factory”) that it’s valuable to occasionally come up for air to get a fresh perspective on things. I had one of those moments this week during a conversation with a Sr. Engineer at one of our customers. After a long whiteboard session about networking within their Data Center, he asked me if it was useful (YES!) and then he said he wasn’t sure how that had anything to do with Cloud Computing.  The rest of the conversation went something like this:

ME: That was great because you highlights many design considerations for building massively scalable data center networks. [SCALABLE]

HIM: Glad it was helpful, but please don’t tell me this is Cloud Computing. This is just the evolution of Data Centers because now VMs and Applications can be mobile.

ME: OK, what do you think Cloud Computing is?

HIM: Cloud Computing is the stuff on the Internet, you know, like Amazon AWS or Google. All the on-demand, self-service, *aaS stuff that marketing people talk about.

ME: OK, fair enough. Does your company (Enterprise -- Financial Services) use any Cloud Computing?

HIM: Are you serious, we have rules about where our data goes, how it’s accounted for and how it’s audited. You can’t do that in Cloud Computing. (NOTE: Not completely true -- Cisco is doing some important work in that space.) Read More »
