The Cloud Native Technology Community, part of the CNBPA Cloud Native Technology Practice Alliance, focuses on evangelizing cutting‑edge cloud‑native technologies and practical implementations. It shares in‑depth content, case studies, and event/meetup information on containers, Kubernetes, DevOps, Service Mesh, and other cloud‑native tech, along with updates from the CNBPA alliance.
The article explains how the open‑source Kro project, backed by Amazon, Google and Microsoft, uses ResourceGraphDefinitions and CEL to turn complex Kubernetes manifests into reusable, parameterized DAGs, offering a safer, more automated alternative to Helm and Kustomize.
This article explains the theory and practical usage of k8gb, a Kubernetes Global Balancer that provides DNS‑based load balancing, fault‑tolerant traffic routing, and seamless failover across multiple clusters to improve resilience, latency, and compliance in cloud‑native environments.
The Kubernetes 1.32 "Penelope" release, launched on December 11, introduces major enhancements such as improved Dynamic Resource Allocation, pod‑level resource specifications, asynchronous preemption, CEL‑based mutating admission, tighter security controls, graceful Windows node shutdown, full consistency test coverage, and several performance and networking upgrades.
This article explains how Kube-OVN leverages OVN configuration parameters to enable non‑intrusive live migration for KubeVirt virtual machines, describes the underlying principle, provides usage instructions, and presents test results showing a drastic reduction in packet loss and migration downtime.
This guide explains how to use KubeVirt 1.4's managedTap feature to configure IPv4/IPv6 dual‑stack networking in bridge mode without modifying source code, covering subnet preparation, plugin registration, and virtual‑machine definition with example YAML and kubectl commands.
SpinKube combines Spin Operator, containerd‑shim‑spin, and an upcoming runtime‑class‑manager to deliver a lightweight, fast‑starting WebAssembly runtime on Kubernetes that addresses the dependency, resource, and image‑size challenges of traditional container‑based serverless architectures.
Microservices are evolving toward 2025 with trends such as edge computing, container orchestration via Kubernetes, DevSecOps, serverless functions, AI-driven management, advanced observability, API gateways, service meshes, multi-language services, event-driven designs, improved data handling, low-code integration, and stronger resilience, reshaping agile, scalable software development.
Kubernetes v1.31 fixes a long‑standing bug where deleting a PVC did not always free the underlying storage, by making the PersistentVolume reclaim policy reliably enforced as a default beta feature, and provides guidance for upgrading and remediation on older versions.
This guide explains the core concepts of Linux namespaces and Cgroups, shows how Kubernetes pod specifications use CPU requests and limits, and provides step‑by‑step commands and parameter details for configuring Cgroup settings to restrict container CPU consumption.
Kubernetes v1.31 "Elli", released after the project’s ten‑year anniversary, introduces 45 enhancements—including 11 stable, 22 beta and 12 alpha features—spanning AppArmor GA, nftables support, multi‑Service CIDR, a new DRA API, image‑as‑volume, CPUManager improvements, and several deprecations and removals to streamline the platform.
