Cilium Service Grid Beta released

Cilium uses the power of eBPF to speed up networking and provide security and observability in Kubernetes. Now Cilium brings eBPF’s strengths to the world of Service Mesh. The Cilium Service Grid uses eBPF to manage connections, enabling the necessary traffic management, security, and observability of a service grid.

In addition to the upcoming Cilium 1.11 release, a new Cilium Service Mesh Beta will also be available soon, featuring:

  • L7 Traffic Management and load Balancing (HTTP, gRPC, etc.)
  • Topology-aware routing across clusters, clouds, and local
  • The TLS to terminate
  • Configure Canary Rollouts, retries, rate limits, fuses, and more via Envoy
  • Use OpenTelemetry and Jaeger integration for tracking
  • Built-in Kubernetes Ingress support

Cilium launched the Service Grid Beta program prior to the official release. To join the Beta program, you can complete this form.

Knative has applied to become an incubator program of CNCF

With the support of the Knative Steering Committee and trademark Board, Google announced its intention to donate the Knative project to the Cloud Native Computing Foundation (CNCF) and submitted a Pull Request.

The Knative project was created and released by Google in 2018 and has since been developed in close collaboration with IBM, Red Hat, VMware, and SAP. The project provides a serverless experience layer on Kubernetes, providing the building blocks needed to build and deploy modern, container-based serverless applications. Over the past three years, Knative has become the most widely installed serverless layer on Kubernetes. Recently, Knative reached an important milestone with the release of 1.0, and becoming an incubator project for CNCF is the next major milestone for Knative.
