Learning Objectives
Amazon Quantum Ledger Database (QLDB) provides a data management approach ideal for scenarios demanding data integrity and transparency, such as real estate transactions.
In this Cloud Lab, you will create the RealEstateLedger in Amazon QLDB, consisting of Properties and Transactions tables for the real estate data verification use case. You will then integrate AWS Lambda functions to facilitate querying and verifying transactions within this ledger. You will develop an API to validate individual records in the Transactions table, focusing on document authentication and integrity. Additionally, you will see an integrated single-page application that leverages the API endpoint to verify real estate transactions recorded in the RealEstateLedger.
After completing this Cloud Lab, you will learn how to implement an immutable ledger system using Amazon QLDB, enhancing data security.
The following is the high-level architecture diagram of the infrastructure you will create in this Cloud Lab:

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.
