Amazon EventBridge
Decouple applications with a serverless event bus
Overview
Amazon EventBridge is a serverless event bus that makes it easier to build event-driven applications at scale using events generated from your applications, integrated Software-as-a-Service (SaaS) applications, and AWS services. EventBridge delivers a stream of real-time data from event sources to targets like AWS Lambda, and other SaaS applications.
✨ Key Features
- Serverless event bus
- Content-based event filtering
- Event transformation
- Integration with over 200 event sources and 20 targets
- Schema Registry for event validation
- Scheduled events (cron jobs)
🎯 Key Differentiators
- Native integration with a vast number of AWS services
- Built-in support for third-party SaaS integrations
- Serverless and fully managed, requiring no infrastructure setup
Unique Value: Simplifies the creation of loosely coupled, scalable applications by providing a centralized, serverless event bus for all of AWS, SaaS, and custom applications.
🎯 Use Cases (5)
✅ Best For
- Triggering a Lambda function when a new file is uploaded to S3
- Starting a Step Functions workflow when an EC2 instance state changes
💡 Check With Vendor
Verify these considerations match your specific requirements:
- High-throughput data streaming (use Kinesis)
- Message queuing with guaranteed delivery order (use SQS FIFO)
🏆 Alternatives
Unlike Kafka which requires cluster management, EventBridge is fully serverless. It focuses on routing events between services, whereas SQS/SNS are for simpler messaging patterns.
