§ CloudEvents 1.0 standard
§ Topic scoping
§ Which topics an application is
allowed to publish to
§ Which topics an application is
allowed to subscribe to
§ Message subscription
§ Applications can subscribe to
published topics
§ Subscribe to topics by either
declarative or programmatic
method
§ Dapr POSTs to HTTP endpoint
§ Message delivery
§ Successfully delivered when
subscriber responds with non-
error response
§ Guarantees “at-least-once”
semantics
§ Message time-to-live (TTL)
§ Message in queue for longer
than the configured TTL is said
to be dead

Cloud-Native Microservices:

An open-source runtime for distributed Cloud-Native applications
Dapr…
36
Encapsulates proven
patterns &
their implementations
as building blocks
Enforces practices &
policies through
configuration
May be overkill if you only
have one language
or few services
Can be be used together
with a service mesh
Allows to pick & chose to
gradually Dapr-ize
applications
Can be run anywhere:
locally, on-prem &
in the Cloud
