@MICROCKSIO #KAFKASUMMIT Event-Driven Secret-Weapon An open source initiative that seeks to improve the current state of Event-Driven Architectures. Created to describe Event-driven APIs using MQTT, AMQP, Apache Kafka, ... “Sister” specification to OpenAPI: same base syntax, use JSON Schema or Avro underhood.

@MICROCKSIO #KAFKASUMMIT AsyncAPI Anatomy Info: metadata and documentation for this asynchronous API: version, title, description, contact and licensing terms Servers: list of brokers with binding details (URLs and security protocols) Channel Item: destination that will be used by the API to publish or consume events. Destination may be mapped to a topic, queue, address name depending on the protocol binding. Operation: whether the application using the AsyncAPI should subscribe or produce messages. Holds its own descriptive metadata Message: the content-type and structure of message headers and payload. May reference schemas of different types (AsyncAPI, JSON, Avro). May contain examples! Components: Common definitions (schemas, traits, messages) like in OpenAPI v3

@MICROCKSIO #KAFKASUMMIT Introducing Microcks Open source Kubernetes-native tool for API Mocking and Testing. It provides an enterprise-grade solution to speed up, secure and scale your API strategy for the digital era. Microcks references any types of APIs or microservices contracts and examples.
