Tracing Step Functions Errors Using AWS X-Ray
In this Cloud Lab, you’ll use the Lambda function to perform operations on DynamoDB. You’ll use Step Functions to create the application logic and identify issues with the help of AWS X-Ray.

Learning Objectives
AWS Step Functions helps build business-critical applications by integrating other AWS services. Step Functions provides built-in controls to examine the state of each step. It also helps ensure that your application runs in order and as expected.
AWS X-Ray helps analyze and debug distributed applications. You can use AWS X-Ray to monitor application traces, including the performance of calls to downstream components or services. X-Ray also helps identify issues and opportunities for optimization.
In this Cloud Lab, you’ll configure a state machine using AWS Step Functions and monitor the execution of your state machine using AWS X-Ray. The state machine will simulate a simple transaction processing service that uses a Lambda function to process the transactions. The transactions are validated using data stored in a DynamoDB table, and the transaction history is maintained in another DynamoDB table.
By the end of this Cloud Lab, you’ll be able to configure state machines using AWS Step Functions, set up Lambda functions, and configure DynamoDB tables. The provisioned infrastructure diagram by the end of this Cloud Lab is shown below:

Your method is simple, straight to the point and I can practice with it everywhere, even from my phone, that's something I have never had in other learning platforms.
I highly recommend Educative. The courses are well organized and easy to understand.
I prefer Educative courses because they have a nice mix of text & images. I find that with full video courses, it can often be too easy to go into passive learning mode.
