Speed-up Kafka delivery with AsyncAPI & Microcks

Apache Kafka is getting used as an event backbone in new organizations every day. We would love to send every byte of data through the event bus. Like traditional REST APIs, a contract-first approach is beneficial when designing event-driven architectures. In the case of asynchronous APIs, we have the AsynAPI specification to document the endpoints where the schema of the records becomes the main part of the contract payload. Microcks allows us to deploy a testing and mocking platform to have a unified view of the endpoints to speed up application delivery.

7. @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.
8. @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
9. @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.
