Cloud-Agnostic Design for Fun and Profit

summary
Two-year case study of a startup that keeps running nearly free on rotating startup credits by rebuilding the same platform across providers. Uses Kubernetes everywhere, deploys everything as Helm charts orchestrated by helmfile, boots clusters with terraform modules per provider and a single bootstrap helm chart for cloud-specific bits. Claims zero-to-fully-operational in minutes, achieved 15% instance-cost swings between providers, migrates production by straddling consensus nodes (Hyperledger Fabric), and found real failures — e.g., ModSecurity defaults blocking demos — which required concrete config fixes.
