The Amazon Quantum Ledger Database (QLDB) is a fully managed ledger database that provides a transparent, immutable, and cryptographically verifiable transaction log owned by a single entity. It’s ideal for use cases that require a complete and verifiable history of data changes, such as financial systems, supply chains, or any application needing a comprehensive audit trail.

When to Use AWS QLDB

Opt for AWS QLDB when you need:

• Data Immutability and Integrity: For applications where it’s critical to have an immutable and easily auditable transaction log.
• Operational Efficiency: When you want to simplify application infrastructure by eliminating the need to build and maintain a custom ledger.
• Cryptographic Verification of Transparency: If proving the integrity of transactions and data transparently and securely is required.

Differences Between RDS and QLDB

• RDS (Relational Database Service): Is a relational database service supporting various database engines like MySQL, PostgreSQL, Oracle, etc. It’s optimized for CRUD (Create, Read, Update, Delete) operations and suits applications that demand complex data relationships.
