CloudEvents: A Common Language for Event-Driven Systems

by Shriira Press

CloudEvents is a CNCF specification that standardizes how events are described, so every system, language, and platform can produce and consume them the same way. This free book teaches it from the ground up: the problem of incompatible event formats, the anatomy of a CloudEvent and its core attributes, context attributes and extensions, the data payload and content types, serialization formats and protocol bindings (HTTP, Kafka, MQTT) in structured and binary modes, the SDKs and tooling ecosystem, event-driven and serverless patterns, schemas and safe versioning, and security and reliability. Ten focused chapters with real JSON, code, and clear diagrams that take you from the spec to building interoperable, evolvable, observable event-driven systems.
