What are CloudEvents in cloud computing?

• A. A protocol for streaming logs between services
• B. A data format for tracing distributed requests
• C. A schema for API version negotiation
• D. A set of standards for describing event data in a common way

Answer: (D)

CloudEvents define a common language for event data, so different services and cloud platforms can exchange events without bespoke schemas. It’s a standard that specifies a set of core attributes—like id, source, type, specversion, time, and data content type—along with the actual event payload. This uniform description makes events portable across diverse systems and enables consistent routing, filtering, and processing by event buses, message brokers, and cloud services. CloudEvents also supports different transport bindings (such as HTTP) and two ways to carry the event: in structured mode, the entire event is serialized as one payload; in binary mode, the attributes are sent as headers and the data is the body. This clarity and interoperability is what makes CloudEvents so useful in event-driven architectures. It’s not a protocol for streaming logs, not a data format for tracing distributed requests, and not a schema for API version negotiation.
