The technology industry is continuously obsessed with the shiny new thing. Often, after scratching the surface of such conceptual innovation, one finds a core of old ideas newly applied and wrapped in ambiguous jargon. The result is an appealing idea, open to multiple interpretations, that leaves everyone free to project meaning and relevance to their particular situation. Such is the case with immutable infrastructure. The term describes a modern application of a well-worn build automation concept that, in practice, is more about automatable change and software platforms than immutable systems and hardware infrastructure. We aren't talking about a hardware appliance molded in ceramic that does one thing, one way, for all time, i.e., actual immutable infrastructure.

Bimodal IT doesn't rely on just one coding construct, one IT operations tool or one platform. The shift to treating applications in entirely different ways is a mix of cultural and technological advancement.
Despite the shiny new term, immutable infrastructure is simply a new approach to a familiar concept. And like all great concepts, it's best explained with pizza.
