The DELAR Model

Joseph Wright — March 28, 2026

Background The DELAR model is something I developed after years of doing IaC with various tools and finding myself reusing the same patterns. I wanted to explain how it works in a way that didn’t involve digging through code. Since everything was patterned in layers, I thought, what if I had a diagram similar to the OSI model for networking, but for IaC? I could use that as the starting point and it would give me a vocabulary to discuss it more easily.
