InfoQ: Netflix Titus Adds Single-Tenant VM Isolation for Containers
Netflix added a single-tenant mode to its Titus container platform that runs one task alone on a right-sized EC2 instance, with the Compute/Platform team still owning host patching. The post says first adopters are stateful, high-throughput streaming workloads and that shared-kernel tuning did not fully close the performance isolation gap. Netflix describes the mode's launch latency cost and that it published no benchmark scores.
What changes for platform teams
Platform teams running shared Kubernetes can borrow the pattern of dedicated tainted node pools with anti-affinity and repacking disabled, which Netflix recommends only for large, long-running, disruption-sensitive workloads. The trade-off is slower launches and lower packing efficiency for small instances.
