Google Kubernetes Engine vs MicroK8s

Google Kubernetes Engine is a managed environment for running containerized applications. It manages the Kubernetes control-plane life cycle for each cluster, from creation to deletion. Teams using Autopilot can hand node provisioning, scaling, scheduling and infrastructure management to Google, while users who prefer can manage nodes themselves. Autopilot also includes automatic capacity right-sizing and per-pod pricing. GKE supports GPU and TPU workloads and connects with AI Hypercomputer for machine-learning and high-performance computing. The product page states that clusters can reach 65,000 nodes. Security features include visibility into configuration issues and risks, agentless scanning for critical vulnerabilities, workload isolation through GKE Sandbox and hardware-based encryption for data in use with Confidential GKE Nodes. Fleets and Teams help organize clusters and workloads across teams. It also supports conformant attached Kubernetes clusters and says applications can run unmodified on on-premises hardware or in public cloud. Windows Server node images and containers are unavailable in Autopilot. A free tier and trial are listed, with a $9/mo starting price.

MicroK8s is a lightweight Kubernetes distribution that can run on a single node or scale to a high-availability production cluster. It is positioned for developer workstations, production, public clouds, edge deployments, IoT and embedded software-vendor platforms. The self-hosted distribution supports Linux, macOS and Windows, and packages upstream Kubernetes services in a minimal CNCF-certified distribution. Three or more nodes enable Dqlite-backed high availability and automatic recovery after a node failure. Strict confinement restricts workloads to explicitly granted files, system resources and hardware. Cluster API can automate cluster creation and lifecycle management through YAML manifests, including rolling HA upgrades. GPU workloads can use the NVIDIA GPU Operator, including NVIDIA Multi-Instance GPU. Official and community addons provide services such as DNS, certificate management, Prometheus, Istio and dashboards. Security updates apply automatically by default, with rollback on failure, and Kubernetes upgrades can be done with one command. MicroK8s has no license fees. Ubuntu Pro subscriptions are also listed, including $25 a year for a workstation subscription and $500 a year for a server subscription with unlimited VMs.
