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.
