Introduction Event based integration
Introduction Event based integration
Event-Driven Integrations in a Nutshell
Event-Driven Integrations Benefits
Business real time updates on events in other business
applications
Events are significant changes in state
Loose coupling resulting in increased flexibility and scalability
(e.g. BusinessPartner changed in SAP S/4HANA)
Easy re-use of existing eventing infrastructure providing more
Event Brokers inform Event Consumers of comfort
events in Event Sources Open standards allowing to cross vendor boundaries
Events can be notification events or data events
Event-Driven integrations use asynchronous
patterns and loose coupling
In an SAP context we typically talk about Event-
Driven Extensions and Event-Driven
Integrations
Customer 5
What is an event in an SAP context?
An event is a significant change in state
The event description holds context and data
of the actual event
Notification Events or Data Events can be
sent from the event source to inform other
systems, microservices, and applications of the
change
A message holding the event description in an SAP, Google, Microsoft, Amazon, Alibaba,
encoded format is sent via an event broker IBM, Oracle … support cloudevents
Event consumers have registered with the
event broker and are informed of the event

Notification Events: Advantages and Challenges
Advantages
• Very small
• Only minimal required data set, access to data
can be controlled well
• Depending on number of required API calls to
fetch additional data, can be very efficient
Challenges
• Additional synchronous step required
• Depending on number of required API calls to
fetch additional data, can be inefficient
• Suitable API needed, so it is not sufficient to
just have a suitable event.
Customer 9
What is a Data Event?
Data Event contains
full data set
of business object for which
significant change
has happened
• No additional backend call needed
• A lot bigger
• Potentially contains sensitive data
• Raises topics like data access and protection

Data Events: Advantages and Challenges
Advantages
• All potentially needed data included in event
• No additional backend call needed
• A lot bigger
• Good for use cases in which the consumer
requires a full data set in majority of cases
Challenges
• Loss of control in respect to potentially sensitive
data
• Raises topics like data access and protection
• Higher resource consumption for source, event
broker and consumer
Customer 13
APIs vs. Events
Application programming interfaces are a contract
between client and server.
Synchronous and blocking.
Need to be called actively.
Events inform interested parties on significant changes.
Asynchronous and non-blocking.
Register once - no additional action needed.

Benefits of event-driven architectures
▪ Loose Coupling results in flexibility and scalability
▪ Responsive applications that react to events in other
systems and applications in real time allowing for a new
kind of integrations and extensions
▪ Incremental Growth by adding event consumers and
event sources step by step resulting in better
operations and improved quality
▪ Improved fault tolerance by applying suitable patterns
▪ Facilitates pay-per-use consumption saving money by
removing “always on”
Customer 17
Challenges of event-driven architectures
▪ Decoupled communication makes monitoring and
understanding what is going on in an event-driven
landscape hard
▪ Tracing and debugging can be more difficult than in
traditional landscapes due to highly parallel nature of
EDAs
▪ Data security to be watched closely when using data
events
