Starting today, Amazon EventBridge cross-account event delivery is available in the AWS GovCloud (US) Regions. This feature extends the ability of businesses to enhance their architecture by simplifying event management across different accounts. In today’s guide, we’ll explore the nuances of Amazon EventBridge, focusing on its capabilities, advantages, and practical applications that can streamline workflows and enhance security.
What is Amazon EventBridge?¶
Amazon EventBridge is a powerful serverless event bus that provides an effective mechanism for building event-driven applications. With EventBridge, developers can manage and route events between applications, AWS services, and even external SaaS applications seamlessly. This transformative technology underpins the cross-account event delivery feature now available in AWS GovCloud (US-EAST) and (US-WEST) Regions.
Key Features of Amazon EventBridge¶
- Event Routing: Events can be routed based on patterns, enabling developers to build dynamic applications that respond to events.
- Built-In Integrations: The service integrates with a variety of AWS services and SaaS applications.
- Scalability: Being serverless, EventBridge can scale automatically based on the request volume without incurring downtime.
- Security: Leveraging AWS Identity and Access Management (IAM), EventBridge helps maintain strict control over who can send and receive events.
The Importance of Cross-Account Event Delivery¶
Cross-account event delivery was introduced to facilitate enhanced collaboration between different teams working under separate AWS accounts. By allowing events to be sent directly from one AWS account to another, organizations can significantly boost productivity and operational efficiency.
Benefits of Cross-Account Event Delivery¶
- Improved Security: By isolating resources into different accounts, organizations can better adhere to the principle of least privilege.
- Streamlined Processes: Teams can manage their own setups without requiring a centralized event management system, promoting independence.
- Cost Reduction: Direct cross-account delivery eliminates the need for intermediary infrastructure, significantly reducing costs.
How It Works¶
When an event is sent from an Amazon EventBridge Event Bus, it can target services in another AWS account directly. The receiving account only needs to ensure that the respective IAM permissions are granted to allow access to selected services, hence allowing for streamlined operations between accounts.
Supported AWS Services for Cross-Account Delivery¶
- Amazon SQS: Message queuing service allowing for reliable communication between distributed components.
- AWS Lambda: Serverless compute service that runs code in response to triggers, ideal for processing events.
- Amazon Kinesis Data Streams: Provides real-time streaming of data, enabling applications to process large streams of event data.
- Amazon SNS: Simple Notification Service for sending messages across different services.
- Amazon API Gateway: Allows developers to create, publish, maintain, monitor, and secure APIs at scale.
Setting Up Cross-Account Event Delivery¶
Setting up cross-account event delivery using Amazon EventBridge involves several steps:
- Create an Event Rule: In the source account, you need to create an event rule specifying the type of events you wish to route.
- Define Permissions: Set up resource-based IAM policies on the target resource in the destination account to allow event delivery.
- Route Events: Configure the EventBridge to send the events directly to the designated destination within the other AWS account.
Example Use Case¶
Suppose you are managing a company with multiple teams handling different aspects of your cloud infrastructure. The DevOps team might manage one AWS account, while the User Experience team manages another. With cross-account event delivery, the DevOps team can push relevant events (like changes to continuous integration processes) directly to the User Experience team’s SQS queue, enabling them to react promptly without the need for complex routing or middleware.
Best Practices for Using EventBridge in a Cross-Account Setup¶
- Utilize Resource-Based Policies: Ensure that resource-based policies are tightly scoped based on the minimum necessary permissions required by the receiving account.
- Monitor Event Traffic: Utilize CloudWatch to track event delivery and set alarms on delivery failures to quickly identify issues.
- Optimize Event Filtering: Implement filtering rules to ensure that only relevant events are sent over, reducing noise and improving processing efficiency.
- Secure Secrets and Credentials: Use AWS Secrets Manager or AWS Systems Manager Parameter Store for managing sensitive information, ensuring that applications in different accounts can switch seamlessly.
- Leverage Versioning: Adopt versioning when defining rules, as this can help in making changes to your EventBridge setup without breaking existing functionality.
Conclusion¶
The launch of Amazon EventBridge cross-account event delivery in AWS GovCloud (US) Regions presents a significant advancement for organizations seeking to streamline their event-driven architectures. By directly linking events between accounts, businesses can improve collaboration, enhance security, and reduce infrastructure complexity. Embracing this technology not only helps organizations to modernize their applications but also aligns with best practices around cost-efficiency and security.
In today’s fast-paced digital landscape, the ability to utilize Amazon EventBridge effectively can transform how teams interact with data and automate workflows. So, if you’re looking for a solution that brings together disparate AWS accounts for seamless event management, incorporating cross-account event delivery into your AWS strategy will be pivotal.
For those keen on how to improve event management and communication between teams, consider integrating the Amazon EventBridge cross-account event delivery feature now available in AWS GovCloud (US) Regions.
