Google Kubernetes EngineSecurity Managed Security by Google ● Control plane security – Google does the control plane management (Mater VM, Scheduler, Cntroll manager, API server, etcd, CA, IAM, logging to stackdriver,) & Patching the contol plane. ● Node security – Google handles K8s comoponents, COS (Chromium OS), logging & monitoring. Autoupgarde & security patches automatically rolled out. Manage base images. – Live migration: Node auto upgrade is like adding new node and drain the work from old. ● Workloads: User need to secure workloads. Protect the secret with Cloud KMS or KMS plugin (Vault).
