How to Seamlessly Integrate Cloud Services with Alibaba EventBridge

EventBridge Overview

EventBridge is Alibaba Cloud’s serverless event bus that standardizes event formats, provides unified push/pull protocols, and offers downstream components such as schema registration, event analysis, and dashboards. It breaks data silos and enables rapid event‑driven integration.

OSS Unzip Service Example

Steps to build an online file‑unzip service triggered by OSS events:

Create an OSS bucket with zip and unzip directories.

Deploy a HTTP endpoint that downloads the uploaded zip file, unzips it, and uploads the result to the unzip folder.

Create an EventBridge rule that matches uploads to the zip folder and forwards the event to the HTTP endpoint.

Create a second rule that watches the unzip folder and forwards notifications to a DingTalk group.

Source code and deployment YAML:

EventBridge extracts parameters via JSONPath, allowing variables to be injected into templates before delivery.

Custom Event Source to RDS

Demo that filters custom MNS events and stores qualified records in an RDS table ( name, age).

Create an MNS queue and an RDS instance with a table.

Configure a custom event bus with the MNS queue as the provider.

Define a rule that filters events where age > 10 using the following JSON filter:

{</code><code>  "source": ["my.user"],</code><code>  "data": {</code><code>    "messageBody": {</code><code>      "age": [{ "numeric": [">", 10] }]</code><code>    }</code><code>  }</code><code>}

When the rule’s target is the RDS database, messages with age greater than 10 are inserted; others are filtered out.

Event Stream: RocketMQ to MNS

Lightweight 1:1 routing without a central bus. The example routes messages from a RocketMQ topic (tag mns) to an MNS queue.

Create an event stream, select the RocketMQ instance as source, and set the tag filter to mns.

Leave the event pattern empty to match all messages.

Select MNS as the target and choose the destination queue.

Start the event stream task.

Only messages with the mns tag are delivered to the MNS queue.

Key Takeaways

EventBridge standardizes event format, ingestion protocol, and component tooling. JSONPath filtering, rule‑based routing, and event streams enable fully serverless, event‑driven pipelines across Alibaba Cloud services.
