Ambassador: Building a Control Plane for an Envoy-Powered API Gateway on Kubernetes

This article provides an insight into the creation of the Ambassador open source API gateway for Kubernetes, and discusses the technical challenges and lessons learned from building a developer-focused control plane for managing ingress or ‘edge’ traffic within microservice-based applications. Key Takeaways Developed by Datawire, Ambassador is an open source API gateway designed specifically for use with the Kubernetes container orchestration framework. At its core, Ambassador is a control plane tailored for edge/API configuration for managing the Envoy Proxy “data plane”.

Envoy itself is a cloud native Layer 7 proxy and communication bus used for handling “edge” ingress and service-to-service networking communication. This article provides an insight into the creation of Ambassador, and discusses the technical challenges and lessons learned from building a developer-focused control plane for managing ingress traffic within microservice-based applications that are deployed into a Kubernetes cluster. Migrating Ambassador to the Envoy v2 configuration and Aggregated Discovery Service (ADS) APIs was a long and difficult journey that required lots of architecture and design discussions, and plenty of coding, but early feedback from the community has been positive.

Poseidon-Firmament Scheduler – Flow Network Graph Based Scheduler

In this blog post, we briefly describe the novel Firmament flow network graph based scheduling approach (OSDI paper) in Kubernetes. We specifically describe the Firmament Scheduler and how it integrates with the Kubernetes cluster manager using Poseidon as the integration glue. We have seen extremely impressive scheduling throughput performance benchmarking numbers with this novel scheduling approach.

The State of Kubernetes Configuration Management

Configuration management is a hard, unsolved problem. We share some unique insights about the strengths and weaknesses of several popular K8s config management tools. Of all the problems we have confronted, the ones over which the most brainpower, ink, and code have been spilled are related to managing configurations.
