Martin Casado is one of the smartest people I've met in my career in IT (AWS, VMware, etc).<p>This phrase is key:<p>"You’re crazy if you don’t start in the cloud; you’re crazy if you stay on it"<p>Perhaps I'd say that "you're crazy if you keep all your IT on it, as you scale".<p>There's still a case to be made for a small % of your workloads in the cloud. The flexibility is priceless. But for everything else, there's a well managed on-prem.<p>Side note: interesting how, after Mark Andreessen's disastrous post on techno-optimism a few days ago, I approached the reading of this article with rolled eyes and low expectations. Seeing Marting Casado as the author immediately changed it, however.
