Episode notes
LinkedIn's Container History
- LinkedIn used a custom container runtime and scheduler for years.
- Migrating to Kubernetes due to increasing complexity of maintaining the old system.
Stateful Workloads on Kubernetes
- Kubernetes can support stateful workloads, even databases, with deep understanding and full-stack control.
- LinkedIn runs stateful applications using local disks due to performance concerns with network storage.
Kubesception at LinkedIn
