Amazon EventBridge announces up to 94% improvement in end-to-end latency for Event Buses

Amazon EventBridge Event Buses announces up to 94% improvement in end-to-end latency for Event Buses, since January 2023, enabling you to handle highly latency sensitive applications, including fraud detection and prevention, industrial automation, and gaming applications. End-to-End latency is measured by the time taken from event ingestion to first event invocation attempt. This lower latency enables you to build highly responsive and efficient event-driven architectures for your time-sensitive applications. You can now detect and respond to critical events more quickly, enabling rapid innovation, faster decision-making, and improved operational efficiency.

For latency-sensitive mission-critical applications, even small delays can have a big impact. To address this, Amazon EventBridge Event Bus has been able to significantly reduce its average latency from 2235.23ms measured in January 2023, to just 129.33ms measured in August 2024 at P99. This significant improvement in latency allows EventBridge to deliver events in real-time to your mission critical applications.

Amazon EventBridge Event Bus’ lower latency is applied by default across all AWS Regions where Amazon EventBridge is available, including the AWS GovCloud (US) Regions, at no additional cost to you. Customers can monitor these improvements through the IngestionToInvocationStartLatency or the end-to-end IngestionToInvocationSuccessLatency metrics available in the EventBridge console dashboard or via Amazon CloudWatch. This benefits customers globally, and ensures consistent low-latency event processing for customers, regardless of your geographic location.
