Event Bridge vs AWS CloudWatch

AWS EventBridge and AWS CloudWatch offer distinct functionalities for mobile applications:

AWS EventBridge is a serverless event bus that enables event-driven architecture by routing events from your applications, SaaS applications, and AWS services to the appropriate destinations. For instance, in a mobile app, EventBridge can automate workflows, such as sending a notification to a user when they complete a task or syncing data across systems in real-time.

AWS CloudWatch is a monitoring and observability service that provides insights into application performance and operational health. It collects logs, metrics, and event data, allowing you to monitor and alert on issues such as increased error rates or slow response times. In a mobile app context, CloudWatch can help track user engagement metrics, monitor backend service performance, and alert developers to potential issues before they impact users.

In essence, EventBridge facilitates application integration and event-driven processes, while CloudWatch focuses on monitoring, logging, and performance insights to ensure smooth operation and quick issue resolution in mobile applications.

I assume you mean CloudWatch Events. If this is the case, CWE and EventBridge buses are the same thing. The default Event Bus in EventBridge is the same as the one in CloudWatch Events.

Both of them are not very relevant to Mobile Applications. They are relevant for interactions between micro services. The service that can be used to send notifications to mobile devices is SNS, which allows sending e-mails, SMS and mobile push notifications.

If this is not what you mean, please elaborate some more on your question.
