One standard envelope for events — interoperable across clouds, languages, and transports.

Welcome to CloudEvents: A Common Language for Event-Driven Systems.

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.

This title is part of the ShriIra library and is free to read in full, right here — our small contribution to making world-class knowledge easy to reach.

A note on reading it: open the Contents menu at the top of the reader to jump between chapters, use the Aa menu to set a comfortable text size, theme (light, sepia, or night), and single- or two-page layout. Your place is saved automatically, so you can always pick up where you left off.

We hope it serves you well.
