typhoon

An event bridge for applications and services build on an event mesh with a team-oriented self-service control plane.

Design

Every software system has design goals. Properties that it should provide io its users to create value. Typhoon has the following design goals:

• Team-based self-service control plane. Teams control their own event sources, triggers, and targets. They also control their users their permissions.
• Event mesh. The system is capable to route events from producers to consumers in hybrid cloud environemts.
• Streaming. The system is capable to stream events from producers to consumers. That means it is capable of replaying events not only queueing them.
• Event bridging. The system is capable to bridge events from different sources to different targets, also transforming them. Furthermore, this should use a declarative approach.
• Scalability. The system is capable to scale horizontally and vertically.
• Resilience. The system is capable to recover from failures.
• Security. The system is capable to secure the communication between producers and consumers.
• Open standards. The system is based on open standards like NATS.io and Knative Eventing.

Overview

Typhoon is built on top of NATS.io and Knative Eventing. It provides a control plane for managing event sources, triggers, and targets. It also provides an API for managing the control plane.

Helm

Helm can be used to install Typhoon to your Kubernetes cluster.

helm repo add typhoon https://zeiss.github.io/typhoon
helm repo update

Install Typhoon to your cluster in a typhoon namespace.

helm install typhoon typhoon/typhoon --create-namespace --namespace typhoon

Development

You can use minikube to run a local Kubernetes cluster.

minikube start

You need to install Serving and Eventing for Knative.
