AWS EventBridge

AWS EventBridge is a serverless event bus service that makes it easy to connect applications using events. It provides a way to ingest, filter, and route events from various sources to targets in your AWS environment, facilitating event-driven architectures.

Key Features

• Event Bus: Allows you to create event buses to route events from different sources to target services.
• Event Filtering: Provides filtering capabilities to process only specific events based on rules and patterns.
• Event Replay: Allows you to replay past events for debugging or reprocessing.
• Integration with AWS Services: Seamlessly integrates with other AWS services such as Lambda, SQS, SNS, and Step Functions.
• Schema Registry: Maintains a schema registry to manage and discover event schemas.
• Custom Events: Supports custom events from your own applications and services.

Architecture Overview

The following diagram illustrates how AWS EventBridge routes events through its architecture:

• Event Sources: Events can come from AWS services, custom applications, or SaaS applications.
• Event Bus: Events are sent to the EventBridge event bus, where they are processed based on defined rules.
• Event Rules: Rules filter and route events to the appropriate targets.
• Targets: Event targets can include Lambda functions, SQS queues, SNS topics, Step Functions, and more.
• Schema Registry: Events and their schemas are managed in the schema registry for better integration and management.

Use Cases

• Application Integration: Integrate different services and applications by routing events between them.
• Event-Driven Architectures: Build and manage event-driven architectures that react to events in real time.
• Workflow Automation: Trigger automated workflows based on specific events or patterns.
• Real-Time Analytics: Collect and process events in real time for analytics and monitoring purposes.

Integration with Other AWS Services

AWS EventBridge integrates with a variety of AWS services to provide a comprehensive event-driven solution:

• AWS Lambda: Invoke Lambda functions in response to events for serverless processing.
• Amazon SQS: Send events to SQS queues for decoupling and asynchronous processing.
• Amazon SNS: Publish events to SNS topics for notifications and further event propagation.
• AWS Step Functions: Trigger Step Functions workflows to orchestrate complex processes based on events.
• AWS Glue: Integrate with AWS Glue for ETL operations based on events.

Things to Remember for the Exam

• AWS EventBridge is a serverless event bus service for connecting and routing events between AWS services and applications.
• Key features include event buses, filtering, replay capabilities, schema registry, and custom events.
• Understand the architecture of EventBridge, including event sources, event buses, rules, targets, and schema registry.
• Familiarize yourself with use cases such as application integration, event-driven architectures, workflow automation, and real-time analytics.
• Be aware of how EventBridge integrates with services like Lambda, SQS, SNS, Step Functions, and Glue.
