Retina

Retina is a cloud-agnostic, open-source Kubernetes network observability platform that provides a centralized hub for monitoring application health, network health, and security. It provides actionable insights to cluster network administrators, cluster security administrators, and DevOps engineers navigating DevOps, SecOps, and compliance use cases.

Retina collects customizable telemetry, which can be exported to multiple storage options (such as Prometheus, Azure Monitor, and other vendors) and visualized in a variety of ways (like Grafana, Azure Log Analytics, and other vendors).

Punq

Punq streamlines Kubernetes cluster management through an intuitive WebApp and a user-friendly CLI, designed to simplify the lives of DevOps professionals.

It offers unified team collaboration, comprehensive log access, and a sophisticated workload editor, facilitates seamless oversight and manipulation of clusters spanning various infrastructures.

This project is dedicated to enhancing operational efficiency within Kubernetes environments, with a particular focus on bolstering team-based workflows.

Kube Startup CPU Boost

Kube Startup CPU Boost is a controller that increases CPU resource requests and limits during Kubernetes workload startup time. Once the workload is up and running, the resources are set back to their original values.

Note: this is not an officially supported Google product.

crik

crik is a project that aims to provide checkpoint and restore functionality for Kubernetes pods mainly targeted for node shutdown and restart scenarios. It is a command wrapper that, under the hood, utilizes criu to checkpoint and restore process trees in a Pod.

It is a work in progress and is not ready for production use.

Kubero

Kubero is a fully self-hosted Internal Developer Platform (IDP) that brings the workflows of Heroku to your Kubernetes cluster. It enables you to deploy your applications with a few clicks. It has a built-in CI/CD pipeline and supports multiple staging environments.

CNCF Incubates Strimzi to Simplify Kafka on Kubernetes

The Cloud-Native Computing Foundation (CNCF) approved Strimzi as an incubating project to streamline the deployment of Apache Kafka on Kubernetes. Strimzi provides a Kubernetes-native way to interact with Kafka through a set of operators that extend the Kubernetes API making it easier to configure, deploy, and operate Kafka on Kubernetes.

Istio announces the beta release of ambient mode

Istio, the most widely adopted service mesh, proudly announces the upcoming beta release of ambient mode in version 1.22.

Istio’s ambient mode is designed for simplified operations without requiring changes or restarts to your application. It introduces lightweight, shared node proxies and optional Layer 7 (L7) per-workload proxies, thus removing the need for traditional sidecars from the data plane. Compared with sidecars, ambient mode reduces memory overhead and CPU usage by over 90% in many cases. Under development since 2022, the beta release status indicates Istio’s ambient mode features and stability are ready for production workloads with appropriate cautions.

Announcing the OpenFeature Web SDK v1

The article announces the release of the OpenFeature Web SDK v1. The SDK is the result of years of research and industry consensus, aiming to provide a performant, powerful, and flexible feature management solution with broad support for preferred tools and in-house solutions. The Web SDK serves as a foundational SDK that can be used independently and also paves the way for framework-specific implementations. It emphasizes the importance of a vendor-neutral Web SDK to cater to the vast and evolving web framework ecosystem. The article highlights the differences between using feature flags on the web versus the server, introducing the static and dynamic context paradigms and focusing on the static-context paradigm supported by the Web SDK.
