footnote 5 for infrastructure as code

5 Neal Ford coined the term “polyglot programming.” See this interview with Neal for more about it.

Some friends of mine write this in March 1991 which clearly references 'polyglot programming'. Obviously they were not the first.

https://yarchive.net/comp/polyglot.html ran on more than 20 implementations of seven languages.

I recently bought your book Infrastructure as Code and am enjoying reading it so far. I am struggling to understand Figure 3-1 which illustrates a really fundamental concept. I find the illustration a little ambiguous:

Referring to Figure 3-1, what is the difference between the Infrastructure primitives (Page 28 -Compute Resources in the Infrastructure Platform level) "Virtual Machines", "Physical Servers", "Server Clusters", "Containers", "Application Hosting clusters", "FaaS serverless code runtimes" that apply at the Infrastructure Platform level and the "Servers", "Container Clusters", "Database Clusters" terms depicted at the Application runtime platforms level in Figure 3-1. I am finding it hard to distinguish how the same term "Servers" apply differently at the two different layers / levels.

A specific example depicting a complete sample infrastructure stack will help greatly!
