What is AWS EventBridge?
AWS EventBridge is a serverless event bus that facilitates building event-driven applications at scale. It enables developers to easily connect applications with data from various sources, including AWS services, SaaS applications, and custom applications. By leveraging EventBridge, developers can route real-time data streams to specific targets such as AWS Lambda functions, Amazon Kinesis streams, or Amazon Simple Notification Service (SNS) topics, triggering business workflows or processes in response to events.
How does AWS EventBridge work?
The operation of AWS EventBridge revolves around the concepts of events, rules, and targets. An event is a JSON-formatted message that represents a change in an environment. When an event occurs, it is sent to the EventBridge bus, where a rule determines how to process and route the event. Rules are criteria or patterns that specify actions when an event matches the rule. Targets are destinations for events that match rules and can include AWS services or custom HTTP endpoints. EventBridge processes events by evaluating each incoming event against the defined rules. When an event matches a rule, EventBridge routes the event to the corresponding target for handling, facilitating a decoupled, scalable, and efficient event-driven architecture.
Use Cases
AWS EventBridge finds its utility in various use cases across multiple domains. One everyday use case is application integration, which simplifies connecting and coordinating the components of distributed applications. For example, an e-commerce application can use EventBridge to connect inventory management, order processing, and notification services seamlessly. In automation and orchestration, EventBridge can trigger workflows in response to specific events, such as launching an automated response when a security system detects unauthorized access attempts. Additionally, EventBridge can centralize events from multiple sources in the monitoring and observability space, enabling the aggregation and filtering of logs for enhanced system monitoring and alerting.
Does PubNub use Event-Driven Architecture?
Yes, PubNub operates as an event-driven architecture primarily through its real-time messaging infrastructure, which allows applications to communicate asynchronously by publishing and subscribing to messages across global channels.
At its core, PubNub’s event-driven architecture is its publish/subscribe model. Applications can publish messages with minimal latency, facilitating real-time interactions within and between applications. In addition to PubNub's event-driven architecture, we offer PubNub Events and Actions, allowing you to define your events and actions, giving you access to PubNub-specific events and connecting those to third-party applications.
