Step Functions

 Step Functions

AWS Step Functions is a fully managed service that makes it easy to coordinate the components of distributed applications and microservices using visual workflows. Here is an example of how to create a Step Functions state machine using the AWS SDK for Python (boto3):

python

import boto3

step_functions_client = boto3.client('stepfunctions')

state_machine_name = 'my-state-machine'

state_machine_definition = {

    'Comment': 'An example state machine',

    'StartAt': 'Task1',

    'States': {

        'Task1': {

            'Type': 'Task',

            'Resource': 'arn:aws:states:::lambda:invoke',

            'Parameters': {

                'FunctionName': 'my-function',

                'Payload': {

                    'input': 'Hello, world!'

                }

            },

            'End': True

        }

    }

}

response = step_functions_client.create_state_machine(

    name=state_machine_name,

    definition=json.dumps(state_machine_definition),

    roleArn='arn:aws:iam::123456789012:role/my-role'

)

state_machine_arn = response['stateMachineArn']

print(f"Step Functions state machine {state_machine_name} created with ARN {state_machine_arn}")

This code creates a Step Functions state machine with the specified name, definition, and IAM role. The state machine ARN is printed to the console.
