from VMs and containers to serverless architectures turns
provisioning code onto a piece of hardware into a pure software problem.
While this is an amazing capability and one of the major value
propositions of cloud computing, corporate IT’s uneasy relationship with code (Chapter 11) and lack of
familiarity with the modern development life cycle can make this a
dangerous proposition.
SDX: Software-Defined Anything
Much of traditional IT infrastructure is either hardwired or
semi-manually configured: servers are racked and cabled, network
switches are manually configured with tools or configuration files. Operations
staff, who endearingly refer to their equipment as “metal,” are usually
quite happy with this state of affairs: it keeps the programmer types
