Use scheduled events to invoke a Lambda function

The following code examples show how to create an Amazon Lambda function invoked by an Amazon EventBridge scheduled event.

Java
SDK for Java 2.x

Shows how to create an Amazon EventBridge scheduled event that invokes an Amazon Lambda function. Configure EventBridge to use a cron expression to schedule when the Lambda function is invoked. In this example, you create a Lambda function by using the Lambda Java runtime API. This example invokes different Amazon services to perform a specific use case. This example demonstrates how to create an app that sends a mobile text message to your employees that congratulates them at the one year anniversary date.

For complete source code and instructions on how to set up and run, see the full example on GitHub.
