You are investigating an event-driven architecture. Which is the best choice to mediate events from AWS services or 3rd Party SaaS?

• CloudWatch Events and Event Bridge consist of different API endpoints and features. Both can be used for Event Driven architectures

• CloudWatch Events and Event Bridge have the same API endpoint and pricing. Either can be used since there is no difference

• EventBridge is based on the CloudWatch Event API and infrastructure with the addition of SaaS Event Bus and Event Replay. EventBridge includes CloudWatch Events, so it is recommended to use EventBridge in the future

• CloudWatch Events detects near real-time events regarding changes in AWS resources. Event Bridge has a  60 second delay. You can choose which one to use depending on how much delay is allowed
