SAP Event Mesh is a cloud service that enables the creation of an asynchronous, event-driven architecture between applications. By establishing a publish–subscribe communication model between event producers and consumers, it allows for modern Event-Driven Architecture (EDA). This enables applications to operate independently, ensuring high scalability and loose coupling between systems.Within SAP Integration Suite, the “Advanced Event Mesh” (AEM) service elevates Event Mesh functionality to an enterprise engineering level, offering advanced management, distribution, and monitoring capabilities.
Acts as a bridge between systems publishing and consuming events via topics. Supports multi-broker usage for geographically distributed systems.
SAP applications like S/4HANA, SuccessFactors, or third-party systems can act as event producers or consumers.
Used to manage Event Mesh configurations. In AEM, the transition to Event Portal 2.0 is complete; version 1.0 is no longer supported.
When subscribing to events, content-based filtering and routing rules can be defined to ensure only the relevant consumers receive the necessary events.
A “Stock Update” event from SAP S/4HANA can be routed via Event Mesh to Cloud Integration, for example, to update stock levels in Salesforce in real time. This setup enables automated triggering of business processes.
Basic steps:
Automatically selects the most optimal route between event brokers, ensuring events are delivered to the correct destination.
Brokers operate in active standby mode; automatic failover ensures uninterrupted service in case of failure.
With OpenTelemetry support, the complete path from event source to consumer can be traced. Bottlenecks can be detected, ensuring end-to-end visibility.
Persistent messages can be resent to consumers; useful for replaying messages to systems that encountered errors.
Kafka clusters can be bridged to the AEM event broker system, enabling hybrid environment support.
Messages published in one VPN can be delivered to consumers in another VPN through configured bridging.
Supports broad application integration via AMQP 1.0, MQTT 3.1.1, and HTTP/REST.
Centralized console for broker distribution, event mesh creation, scaling, and monitoring.
Real-time and historical performance data is visualized in dashboards; anomalies and traffic trends can be monitored.
Corporate proxy configurations are supported for Event Portal–broker connections; works with Distributed Tracing.
TLS certificates for brokers can now be uploaded, managed, and deleted via GUI instead of REST API.
Supports static IP for API access, maintaining secure connections during maintenance or migration.
HA brokers can be scaled node-by-node with only ~1 minute downtime.
Supports switching the active node to standby to test failover scenarios safely.
Enables secure authentication from Event Portal using OAuth PKCE; offers more secure access flows.
Clients can use certificates to access the broker. CN name can be mapped to a username; basic authentication can be disabled.
Decoupled Architectures:
Producers and consumers operate independently; inter-system dependencies are kept to a minimum.
Real-Time Processing:
Events are delivered instantly, making processes more agile.
Scalability:
AEM scales horizontally automatically, maintaining performance under high traffic.
Security & Compliance:
Enterprise-grade security is ensured with features like TLS, OAuth 2.0 PKCE, certificate-based authentication, and static IP.
Observability & Management:
Event Portal 2.0, tracing, monitoring, HA operations, and spool replay provide advanced capabilities for operational visibility.
SAP Event Mesh —especially with Advanced Event Mesh— enables organizations to make application integrations more flexible, secure, and observable. From S/4HANA to cloud-based systems and third-party applications, you can build event-driven, real-time workflows that significantly enhance the agility and efficiency of your business processes.
