What They Mean By Serverless Containers
- ZITADEL defines "serverless containers" as running OCI images on a managed platform that scales from zero to thousands without managing servers.
- They chose this to avoid node-level infrastructure overhead and gain fast autoscaling and cost benefits.
Long Kubernetes History Shaped Choices
- Florian recounted early Kubernetes days, from kube-up scripts through OpenShift, and the heavy operational burden it introduced.
- That long experience shifted them toward simpler managed offerings for most workloads.
Identity Workloads Are CPUβHeavy
- Authentication and token handling make the workload CPU-bound due to hashing and signing operations.
- RSA verification is cheap, but password hashing like bcrypt at production iterations can cost hundreds of milliseconds per request.
