I looked at the site before asking my question. It looks like cloud orchestration 101. How is it different from, say, Terraform?
Terraform creates everything and hands you the keys to manage your infrastructure. Fugue continually manages your infrastructure after the deployment with the Conductor. The continuous automatic regeneration of instances make bad boots, noisy neighbors, and transient errors temporary blips rather than problems that must be manually addressed. Fugue continuously enforces your desired state of infrastructure so you don't have to.
