Kind of ironic how the IP video connection sucks so bad, for someone advocating full reliance on the network.
Peterson has a point, some admins refuse to even look at the cloud as an option. The "cloud hugger" metaphor is wrong though, the cloud is not a new version of the local server which is more efficient, performant and clean (sure, there were advantages to having horses too (vs. cars), but no notable advantages related to the main purpose, transportation). The cloud is just a different thing altogether, like an airplane vs. a car. A good admin needs to decide if outsourcing the operations makes sense for each case, also factoring in the costs (and hope the management trusts that decision). It's easy to take too much pride in one's craft, and insist on perfect solutions, when the business maybe only needs a fairly good solution.
At an infrastructure level, using "cloud" tools (i.e. virtualisation, management), is reasonably safe. These are reasonably portable across the remote / on premises boundary, though porting requires some effort.
At the application level, if the plan is to use cloud tools exclusively, it's easy to end up with inconvenient workflows or being stuck with some provider. Inter-operation between applications is sparse. Many cloud applications provide APIs, sure, but if you need a server to call APIs and synchronise data across providers, and the business becomes reliant on those scripts, have you really gained anything..?
