Coinbase has some fairly unusual security and infrastructure requirements. One of these requirements is that every server in our infrastructure is both ephemeral (30 days) and immutable. The deployment process for most applications is fairly straightforward: 12-factor apps are blue/green deployed behind a load balancer. Blockchain nodes, however, present a difficult problem: How do you blue/green deploy a server with 1 TB on disk? In this session, we discuss how we solved this problem in a blockchain-agnostic fashion using a new project, called Snapchain.
