Answer:

Amazon EventBridge offers a pay-per-event pricing model, where you only pay for the number of events delivered to your targets, as well as a capacity-based pricing model for custom event buses.

Under the pay-per-event model, the first 1 million events per month are free. After that, you pay $1.00 per million events for the next 10 million events, and $0.50 per million events for events beyond 10 million.

Under the capacity-based pricing model, you pay a monthly fee based on the number of custom event buses you use and the amount of capacity you reserve for each bus. The pricing starts at $50 per month for one custom event bus with a capacity of 1 GB per second.

To minimize costs while maximizing performance, you can optimize your event patterns and filter rules to reduce the number of unnecessary events that are delivered to your targets. You can also use CloudWatch metrics and alarms to monitor your EventBridge usage and detect anomalies or unexpected spikes in event traffic.
