Amazon EventBridge
Event-driven application integration for modern, loosely coupled systems, built to react in real time
Get in touchAmazon EventBridge
Amazon EventBridge is a serverless event bus service designed to simplify the building of event-driven applications.
It allows AWS services, custom applications and supported SaaS platforms to communicate by passing events between one another, without the need for direct integration. Amazon EventBridge routes events in real time based on defined rules, helping teams decouple systems, automate workflows and respond to changes as they happen, at scale and with minimal operational overhead.

Key features of Amazon EventBridge
Event-driven integration
Amazon EventBridge connects services through events, allowing you to build applications that react to changes in real time without polling or tight coupling between components.
Native AWS service support
EventBridge integrates natively with a wide range of AWS services such as Lambda, Step Functions, SQS, SNS and more, enabling event-based workflows across your entire cloud architecture.
Support for SaaS event sources
It allows direct integration with third-party SaaS providers like Zendesk, Datadog and Auth0, so external events can trigger actions within your AWS environment.
Schema registry and discovery
EventBridge provides a schema registry that stores structure definitions for events, simplifying validation, code generation and documentation.
Flexible routing with event buses and rules
You can define rules to filter and route events based on content. Use default, custom, or partner event buses to organise and control event flows.
Archive and replay
Store past events and replay them later for testing, troubleshooting or compliance purposes without rebuilding test environments or injecting dummy data.
Reliable and highly available
Amazon EventBridge is designed for durability and availability, automatically scaling to accommodate varying volumes without manual intervention.

Reduced system complexity
By decoupling services and replacing point-to-point integrations with events, Amazon EventBridge simplifies how systems communicate making your architecture easier to manage and evolve.
Real-time responsiveness
EventBridge enables applications to react instantly to changes, whether from internal services or external SaaS systems. This supports timely decision-making and responsive digital experiences.
Flexible integration with minimal code
Events can trigger workflows without writing complex orchestration logic. Built-in support for AWS and SaaS services helps reduce development effort and time to production.
Scalability without manual effort
Amazon EventBridge automatically adjusts to changing workloads, handling anything from occasional events to high-frequency activity without the need to scale infrastructure manually.
Improved reliability and fault isolation
Because services are loosely coupled, failure in one part of your system doesn’t necessarily affect others. This improves fault tolerance and supports more resilient applications.
Clear event visibility and management
Through schema discovery, logging and routing rules, EventBridge makes it easier to track and manage events flowing through your architecture.
How we help with Amazon EventBridge
Event-driven systems don’t come together by accident, they require careful design, reliable integration and a clear understanding of how your business responds to change. At Claria, we bring experience and structure to that process.

Team augmentation
Our AWS-certified specialists join your team to deliver or scale your EventBridge initiatives, whether you’re building a new event-driven platform or expanding existing use cases.
Amazon EventBridge Pricing and Cost
Amazon EventBridge follows a pay-per-use model, making it cost-effective for applications with dynamic workloads. Amazon EventBridge pricing is based on the number of events published, matched, and delivered, meaning you only pay for the events your system processes.
There are no upfront commitments and costs are calculated per million events. Additional charges may apply if you use Amazon EventBridge with cross-account or cross-region delivery, schema registries, or archive and replay features.
For organisations building large-scale, event-driven systems or integrating with multiple SaaS and AWS services, it’s essential to estimate usage patterns and design event flows efficiently to keep costs predictable and manageable.
Need help understanding what EventBridge might cost in your environment?
As an AWS Partner, Claria helps organisations plan and optimise Amazon EventBridge deployments, not only from an architectural point of view, but also in terms of cost-efficiency. We can help you:
Estimate usage based on your actual workloads
Design event-driven systems that reduce unnecessary invocations
Identify pricing differences between services like EventBridge, SNS or SQS
When to use Amazon EventBridge
Amazon EventBridge is ideal for organisations that need to connect services, applications, or systems in a loosely coupled, event-driven architecture.
It’s particularly useful when:
You want to decouple applications
Amazon EventBridge enables services to communicate through events rather than direct integration. This simplifies system architecture and allows teams to update or scale components independently.
You need to respond to events in real time
Use EventBridge to build systems that react immediately to business events, such as order placements, user sign-ups, or security alerts, without polling or delay.
You're integrating SaaS and AWS services
Amazon EventBridge makes it easy to receive events from supported SaaS platforms (like Zendesk or Auth0) and route them into AWS for further processing, analysis or automation.
Your workflows require conditional logic
Amazon EventBridge supports event filtering and routing rules, allowing you to direct events to the right targets based on detailed conditions, ideal for operational workflows or compliance actions.
You aim to reduce custom glue code
Instead of writing and maintaining custom integration layers between services, EventBridge allows you to wire systems together declaratively through rules and event buses.
You're building scalable, serverless applications
EventBridge pairs naturally with AWS Lambda, Step Functions and other serverless services, forming the backbone of event-driven applications that scale automatically with demand.

Amazon EventBridge FAQs
Amazon EventBridge is a serverless event bus that makes it easy to connect applications using events. It enables event-driven architectures by ingesting events from AWS services, your own applications, or third-party SaaS platforms and routing them to targets such as Lambda, Step Functions, or SQS.
While SNS and SQS are messaging services, EventBridge is focused on event routing and filtering:
SNS delivers messages to subscribers immediately.
SQS queues messages for later processing.
EventBridge offers advanced event filtering, schema discovery and flexible routing between event producers and consumers, ideal for decoupling large systems or microservices.
Events can come from:
AWS services (e.g. EC2 state changes, CodePipeline events)
Your own applications queues (via the PutEvents API)
Supported SaaS platforms (e.g. Zendesk, Datadog, Auth0)
Schedules (you can define cron or rate-based rules for automation)
EventBridge can route events to multiple AWS targets, including:
AWS Lambda
Step Functions
SQS
SNS
Kinesis Data Streams
EC2 and ECS tasks
API Gateway
Event buses in other AWS accounts or regions
Yes. EventBridge is fully serverless, there’s no infrastructure to provision or manage. It automatically scales to handle the event throughput and maintains high availability without user intervention.
Absolutely. You can send custom events from your applications using the PutEvents API and even create custom event buses to isolate and organise events between different teams or services.
EventBridge allows you to define filtering rules using a simple JSON-based pattern language. Only events that match the pattern are routed to the target. This avoids unnecessary processing and keeps event-driven systems efficient and loosely coupled.
Yes. EventBridge guarantees at-least-once delivery of events and stores them durably across multiple Availability Zones for fault tolerance. You can also use dead-letter queues (DLQs) with targets like Lambda to capture undelivered events.
