IN TRO DUC TION

The most fundamental conception is, as it seems to me, the whole system, in the sense of physics, including not only the organism-complex, but also the whole complex of physical factors forming what we call the environment. … Though the organism may claim our primary interest, when we are trying to think fundamentally, we cannot separate them from their special environment, with which they form one physical system. It is the systems so formed from which, from the point of view of the ecologist, are the basic units of nature on the face of the earth. These are ecosystems.

-Sir Arthur Tansley, “The Use and Abuse of Vegetational Concepts and Terms,” 1935.

We use the term infrastructure more and more to refer to the support system for information technology. Whatever we do with our applications that creates value for our customers, or generates revenue for ourselves, we’re supporting it now with IT infrastructure. It’s all the stuff under the hood. It’s also the part of technology that, when it works right or as well as we expect, we don’t stand in long lines to get a glimpse of, nor do we see much discussion of it on the evening news.

In the stack of technologies with which we work today, there is a growing multitude of layers that are under the hood. With modern hyperconverged servers that pool their compute, storage and memory resources into colossal pools, the network of heterogeneous technologies with which those pools are composed is one layer of physical infrastructure.
