Applying Graph Theory to Infrastructure as Code

Graphs are mathematical structures used to model relationships between objects. Modern infrastructures can be thought of as graphs — compute resource depend on network resources, which in turn depend on access control resources, and so on. At a certain scale, the relationships between all resources in an infrastructure become impractical to reason about.
Terraform builds a graph to model the relationships between resources so operators can safely manage and change infrastructure resources across bare metal, IaaS, PasS, and SaaS. Terraform models and potentially prevents that simple change with unforeseen consequences so operators don't have to.
In this talk, we will explore the graph theory at the heart of Terraform's orchestration engine.

In his career, Paul Hinze has been consistently drawn to Production: its affinity for chaos, its unforgiving nature, and ultimately its deep longing for attention. This has gotten him into trouble again and again. Once, he found himself in charge of production operations at a payments company. Then he stumbled on a globally scaled AWS application, where he worked on deployment and automation.
Today, Paul has finally embraced his true nature at HashiCorp, where he works on tools that help others who feel the same call of Production. --
