Case Study: SeatGeek achieves scalable infrastructure automation with HashiCorp HashiStack

SeatGeek and the HashiStack A Tooling and Automation Love Story

SeatGeek, a ticketing company serving millions of customers, needed a way for a small infrastructure team to manage a large, always-on platform used by more than 100 engineers. With HashiCorp products such as Nomad, Consul, Vault, Packer, Terraform, and Vagrant, SeatGeek set out to replace manual operations with automation, self-service, and strong service discovery and secrets management.

HashiCorp helped SeatGeek build a highly automated HashiStack-based environment: nearly 100% of infrastructure is Nomad-managed, with over 200 Nomad jobs and 2,500+ allocations running on about 200 EC2 instances, all operated by just five engineers. SeatGeek also used custom HashiCorp-based tools like hashi-helper, nomad-helper, and nomad-firehose to streamline Vault unsealing, cluster management, debugging, and visibility, improving reliability and enabling safe scaling and deployment workflows.
