Trigger Multiple Lambda Functions from the same S3 Bucket with Object Key

Amazon EventBridge serves as a versatile event bus service that facilitates seamless integration between AWS services, custom applications, and external resources. This enables developers to build event-driven applications by targeting AWS Lambda functions to process events from multiple sources. A common and powerful use case is configuring EventBridge rules to execute Lambda functions based on events originating from Amazon S3 buckets with the same object key. In this article, we will learn how to apply this rule effectively.*

Prerequisites

Before proceeding, make sure that the following conditions are met:

1. An AWS account with the necessary permissions to create and configure EventBridge rules, Lambda functions, and S3 buckets.
2. Access to the AWS CLI or AWS Management Console to install the required resources.

Step 1: Create an S3 Bucket

If you don’t already have an S3 bucket, follow these steps to create one:

1. Open the AWS Management Console.
2. Go to the S3 service.
3. Click the “Create Bucket” button and follow the instructions to set up your S3 bucket.

Step 2: Create a Lambda Function

Next, you need to create the Lambda function you want to run. Lambda functions can be created using the AWS Management Console or the AWS…
