Amazon EventBridge Features

API Destinations enables you to send events back to many on-premises or software as a service (SaaS) applications with the ability to control throughput and authentication.

You can send events to any web-based application with a web address without worrying about writing custom code or using additional infrastructure. You can configure rules with input transformations that will map the event’s format to the receiving service format. You can also use EventBridge to take care of security and delivery. Learn how to use API destinations by walking through integration examples you can use in your workflows.

API Destinations on Amazon EventBridge is suitable for:

• Developers looking to build service integrations with legacy, modern, on-premises, and SaaS applications
• Developers seeking to accelerate time to market and minimize time spent on building custom integrations to securely connect applications 
  

With Event Replay, you can reprocess past events back to an event bus or a specific EventBridge rule. This feature helps you debug your applications quickly, extend them by hydrating targets with historic events, and recover from errors. See more how archives and replays work in practice.

Event Replay on Amazon EventBridge is suitable for:

• Developers looking to add more durability to their applications
• Developers needing to store their data for compliance reasons
  
• Developers wanting to test and debug their events using events from their archive to simulate real world usage
  

The EventBridge Schema Registry stores event schemas in a registry that other developers can more easily search and access in your organization. Thus, you don’t have to find events and their structure manually. The registry also helps you generate code bindings for programming languages such as Java, Python, or TypeScript directly in your integrated development environment (IDE) so that the event can be used as an object in your code.

By turning on Schema Discovery for an event bus, the schemas of events are automatically discovered and added to the registry, removing the need to create a schema for an event manually. Schemas for Amazon Web Services services are automatically visible in your schema registry.

Schema Registry on Amazon EventBridge is suitable for:

• Developers looking to keep track of different schemas in their organization
• Developers that need an easier way to search for schemas and download code bindings that can be used to write applications that react to events
• Developers looking to save time automatically determining the schema of the event and update the registry
  

EventBridge is a serverless, fully managed, and scalable event bus.  It helps you build reliable and scalable applications at a faster rate. Amazon EventBridge Event Bus enables you to easily communicate between applications and services via events. It reduces the operational overhead without having to provision, patch, and manage servers.

Amazon EventBridge Event Bus is suitable for:

• Developers looking to respond automatically to changes in their applications
  
• Developers looking to keep their data in sync across multiple systems
  
• Organizations that are looking to build Event-Driven Architectures (EDA)
  

Your Amazon Web Services applications can take action based on events that SaaS applications generate. EventBridge is natively integrated with SaaS applications from many providers including Shopify, BuildKite, Datadog, OneLogin, PagerDuty, Saviynt, Segment.io, SignalFx, SugarCRM, Symantec, Whispir, and Zendesk, with additional integrations planned. You don’t need to manage any integration setup such as authentication events from your SaaS provider; they will appear on your event bus.

EventBridge is directly integrated with over 200 event sources and over 20 targets, including Amazon Lambda, Amazon Simple Queue Service (SQS), Amazon Simple Notification Service (SNS), Amazon Step Functions, Amazon Kinesis Data Streams, and Amazon Kinesis Data Firehose, with additional sources and targets planned.

All mutating API calls (all calls except Describe*, List*, and Get*) across Amazon Web Services services generate events through Amazon CloudTrail.

• Developers that want to transfer only the events that they need
  
• Developers that want to reduce the total cost of ownership by filtering only data that is of interest to them

EventBridge provides at-least-once event delivery to targets, including retry with exponential backoff for up to 24 hours. Events are stored durably across multiple Availability Zones (AZs), providing additional assurance your events will be delivered to their destination. EventBridge also provides a 99.99% availability service level agreement (SLA), verifying your applications can access the service reliably.

EventBridge extends its predecessor, Amazon CloudWatch Events, and provides a near real-time stream of system events that describe changes to your Amazon Web Services resources. 

It helps you respond quickly to operational changes and take corrective action. You need to write rules to indicate which events are of interest to your application and what automated actions to take when a rule matches an event. You can, for example, set a rule to invoke a Lambda function to remediate an issue or notify an Amazon Simple Service Notification Service (SNS) topic to alert an operator.

You can monitor your event bus using Amazon CloudWatch metrics, such as the number of times an event matches a rule, or the number of times a target is invoked.

You can use Amazon CloudWatch Logs to store, monitor, and analyze events that are initiated in your environment. CloudTrail helps you monitor calls made to the Amazon EventBridge API.

EventBridge integrates with Amazon Identity and Access Management (IAM) so that you can control which users and resources have permission to access your data and how they can access it. EventBridge supports VPC endpoints and encryption in transit using TLS 1.2. EventBridge is SOC, ISO, and PCI-DSS compliant.

Amazon EventBridge offers flexible pricing, you only pay for events published to your event bus, events ingested for your Schema Discovery, Event Replay, and API Destinations making it cost-effective solution for all organizations. There are no additional charges for rules or event delivery. There are no minimum fees or upfront commitments. All state change events published by Amazon Web Services services are free.
