AWS EventBridge can help organizations build loosely coupled, event-driven architectures and deploy new features faster, while also leveraging it for observability purposes to collect and send data across applications and services. By using EventBridge as an event bus, organizations can centralize monitoring and reduce costs by complementing it with other tools that are stronger in certain areas. Data retention is crucial for root cause analysis, and tools like ChaosSearch offer unlimited data retention via cloud object storage, minimizing costs and eliminating data movement. The combination of EventBridge, ChaosSearch, and Amazon S3 can provide a streamlined centralized logging solution, allowing organizations to scale data analytics while optimizing costs.
