typhoon

An event bridge for applications and services build on top of NATS.io and Knative Eventing/Serving.

Why

AWS EventBridge is a great service to bridge events between different sources and targets in your enterprise. However, it is not a cloud-native solution and it is not open-source.

It is the goal to create a cloud-native and open-source alternative that works on-premise and in the cloud and that has a focus on enterprise-readyness.

Design

• 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.

The accounting should be done via the Operator for NATS Accounting that we provide to configure NATS.io accounts and users.
