Amazon QLDB is a fully managed ledger database that provides a transparent, immutable, and cryptographically verifiable transaction log owned by a central trusted authority. Amazon QLDB tracks each and every application data change and maintains a complete and verifiable history of changes over time.
With Amazon QLDB, your application’s complete change history is immutable – it cannot be altered or deleted – and using cryptography, you can easily verify that there have been no unintended modifications to your application’s data. QLDB uses an immutable transactional log, known as a journal, that tracks every application data change and maintains a complete and verifiable history of changes over time. QLDB provides developers with a familiar SQL-like API, a flexible document data model, and full support for transactions. QLDB is also serverless: there are no servers to manage or read and write limits to configure, and it automatically scales to support the demands of your application. With QLDB, you only pay for what you use.
