Best Network Policy Tools for Kubernetes 2026 — Calico vs Cilium vs Weave Net: Complete Comparison Guide Published February 17, 2026 by Yaya Hanayagi Kubernetes networking security has evolved significantly, and choosing the right network policy tool in 2026 is crucial for cluster security, performance, and operational efficiency. This comprehensive guide analyzes the top network policy solutions available today, comparing their architectures, features, pricing, and real-world performance. Table of Contents Introduction to Kubernetes Network Policies The Network Policy Landscape in 2026 Detailed Tool Analysis Performance Benchmarks Comparison Tables Decision Framework Security Considerations Integration Patterns FAQ Section Conclusion Introduction to Kubernetes Network Policies Network policies in Kubernetes define rules that control traffic flow between pods, namespaces, and external endpoints. By default, Kubernetes allows all pod-to-pod communication—a design that prioritizes connectivity over security. Network policies enable zero-trust networking by explicitly defining allowed communication paths. ...

Best Kubernetes backup tools 2026 have evolved into sophisticated data protection platforms offering application-aware backups, cross-cluster migrations, and automated disaster recovery for cloud-native environments. Leading kubernetes backup tools comparison reveals distinct approaches: Velero dominates with its CNCF-incubated open-source solution and extensive ecosystem support, Kasten K10 by Veeam provides enterprise-grade application mobility with intuitive policy management, Trilio TrilioVault offers point-in-time recovery with granular restore capabilities, Stash by AppsCode delivers declarative backup workflows, Longhorn combines distributed storage with backup functionality, and Portworx PX-Backup enables cross-cluster data protection with CSI integration. Velero vs Kasten pricing models range from free open-source to enterprise per-node licensing, while best k8s backup strategy depends on cluster scale, compliance requirements, and operational complexity tolerance. ...
