Learning Objectives
Amazon Quantum Ledger Database (Amazon QLDB) is a serverless ledger database service by Amazon Web Services (AWS). Amazon QLDB provides a transparent, immutable, and cryptographically verifiable application transaction log. Amazon QLDB maintains a dedicated journal for every transaction, which is used to verify transactions.
In this Cloud Lab, you’ll first create an Amazon QLDB Ledger. Then, you’ll create Lambda functions coupled with a Lambda layer for create, read, update, and delete (CRUD) operations on the Amazon QLDB ledger. The next step is to create a REST API using API Gateway. Next, you’ll consume the API in a React application. Toward the end, you’ll explore how the transactions are verified using the Amazon QLDB ledger.

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.
