K3s vs MicroK8s: both are called 'lightweight Kubernetes,' but the real production divide is HA architecture. We compare K3s's embedded etcd and MicroK8s's dqlite using official documentation data.
How long does failover really take with K3s embedded etcd versus kubeadm stacked/external etcd? We examine the gap between official RTO targets and real-world recovery times, and how failure domains and node counts differ.
K3s vs RKE2 is often reduced to a feature checklist. Using a real production migration incident, we break down CIS Hardening, HA requirements, and storage assumptions to help you choose the right distribution for production.
K3s's etcd snapshots looked healthy every day, yet restore failed during a real outage. Three real-world traps — token management, S3 restore incidents, and cluster-reset pitfalls — reveal what's really at risk in embedded etcd backups.
A deep dive into how live-migrating a K3s control plane VM on Proxmox can break etcd quorum, explained through heartbeat/election-timeout mechanics and Proxmox affinity design, with concrete operational countermeasures.
World Cup broadcasts duplicate every camera feed across two independent paths and simply discard whichever packet arrives second. That seemingly wasteful design shares the same philosophy as Kubernetes high availability and multi-AZ architecture.
Kubernetes high availability isn't achieved simply by adding more replicas. Using the broadcast industry's SMPTE ST 2022-7 dual-path transmission as a lens, this article unpacks what Topology Spread Constraints and multi-AZ design actually mean.
Learn how to run K3s in production with confidence. Covers HA architecture, security hardening, monitoring, backup strategies, and resource management.
Complete guide to building Proxmox VE HA clusters with Corosync configuration, fencing setup, HA groups, failover testing, and maintenance procedures.
