Shared Nothing, Shared Everything: The Truth About Kubernetes Multi-Tenancy, with Molly Sheets

In this episode of KubeFM, Molly Sheets, Director of Engineering for Kubernetes at Zynga, discusses Kubernetes strategies for large-scale applications. She highlights the adoption of Cilium for eBPF networking, Argo CD for managing cluster add-ons, and Capsule for multi-tenancy. Molly addresses why a single cluster per team is unsustainable, how slowing deployments increases risk, and key metrics for multi-tenant environments. She shares insights on incident culture, blameless postmortems, and the importance of aligning Kubernetes architecture with business needs rather than team structures, advocating for multi-tenant clusters while acknowledging the need for separate clusters in specific situations like latency requirements or critical workload isolation.
