Amazon EventBridge is a serverless event bus service that makes it easy to connect applications with data from a variety of sources.
enables building loosely coupled and distributed event-driven architectures.
provides a simple and consistent way to ingest, filter, transform, and deliver events so you can build new applications quickly.
delivers a stream of real-time data from applications, SaaS applications, and AWS services, and routes that data to targets such as AWS Lambda.
supports routing rules to determine where to send the data to build application architectures that react in real-time to all of the data sources.
supports event buses for many-to-many routing of events between event-driven services.
provides Pipes for point-to-point integrations between these sources and targets, with support for advanced transformations and enrichment.
provides schemas, which define the structure of events, for all events that are generated by AWS services.
EventBridge receives an event on an event bus and applies a rule to route the event to a target.
An event source is used to ingest events from AWS Services, applications, or SaaS partners.
An event is a real-time indicator of a change in the environment such as an AWS environment, a SaaS partner service or application, or one of your applications or services.
All events are associated with an event bus.
Events are represented as JSON objects and they all have a similar structure and the same top-level fields.
Contents of the detail top-level field are different depending on which service generated the event and what the event is.
An event pattern defines the event structure and the fields that a rule matches.
Event bus is a pipeline that receives events.
Each account has a default event bus that receives events from AWS services. Custom event buses can be created to send or receive events from a different account or Region.
Rules associated with the event bus evaluate events as they arrive.
Rules match incoming events to targets based either on the structure of the event, called an event pattern, or on a schedule.
Each rule checks whether an event matches the rule’s criteria.
A single rule can send an event to multiple targets, which then run in parallel.
Rules that are based on a schedule perform an action at regular intervals.
A target is a resource or endpoint that EventBridge sends an event to when the event matches the event pattern defined for a rule.
The rule processes the event data and sends the relevant information to the target.
EventBridge needs permission to access the target resource to be able to deliver event data to the target.
Up to five targets can be defined for each rule.
EventBridge allows events to be archived and replayed later.
AWS Certification Exam Practice Questions
Questions are collected from Internet and the answers are marked as per my knowledge and understanding (which might differ with yours).
AWS services are updated everyday and both the answers and questions might be outdated soon, so research accordingly.
AWS exam questions are not updated to keep up the pace with AWS updates, so even if the underlying feature has changed the question might not be updated

A company wants to be alerted through email when IAM CreateUser API calls are made within its AWS account. Which combination of actions should a SysOps administrator take to meet this requirement? (Choose two.)
Create an Amazon EventBridge (Amazon CloudWatch Events) rule with AWS CloudTrail as the event source and IAM CreateUser as the specific API call for the event pattern.
Create an Amazon EventBridge (Amazon CloudWatch Events) rule with Amazon CloudSearch as the event source and IAM CreateUser as the specific API call for the event pattern.
Create an Amazon EventBridge (Amazon CloudWatch Events) rule with AWS IAM Access Analyzer as the event source and IAM CreateUser as the specific API call for the event pattern.
Use an Amazon Simple Notification Service (Amazon SNS) topic as an event target with an email subscription.
Use an Amazon Simple Email Service (Amazon SES) notification as an event target with an email subscription.
