@ZEHICLE #IaC Rob Hirschfeld CEO & Co-Founder RackN & Digital Rebar Why do we care about IaC? To fix bare metal automation, we had to accept that every data center is a snowflake. So we needed to make our automation simple, modular and portable. Simply put - we had to build an IaC platform: Digital Rebar

@ZEHICLE #IaC So is IaC the right term? No. What about SDx or SDDC? They are co-opted for IaaS.
