Create a Lambda function that sends events to EventBridge with routing to Step Functions.
The SAM template contains all the information to deploy AWS resources(the Lambda functions, the EventBridge and the Step Functions workflow) and also the permission required by these service to communicate.
The OrderPublisher Lambda function will be invoked with a JSON payload which will send the message to the EventBridge custom event bus. The event will match a custom event pattern rule which will send the event to the Step Functions workflow. The workflow will start and invoke the OrderState Lambda function which will return a message and display the EventBridge message in CloudWatch Logs.
