Announcing General Availability of Amazon Quantum Ledger Database (QLDB)

Amazon Web Services (AWS) announces general availability of Amazon QLDB, which is a fully managed ledger database that provides a transparent, immutable, and cryptographically verifiable transaction log ‎owned by a central trusted authority.

Amazon QLDB is a new class of database that eliminates the need to engage in the complex development effort of building your own ledger-like applications (e.g., tracing the movement of an item through a supply chain network, tracking the history of credits and debits in banking transactions, or validating incidents filed against an insurance claim). With QLDB, your data’s 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 transaction log, known as a journal, that tracks each application data change and maintains a complete and verifiable history of changes over time. QLDB is easy to use because it provides developers with a familiar SQL-like API, a flexible document data model, and full support for transactions. QLDB is also serverless, so it automatically scales to support the demands of your application. There are no servers to manage and no read or write limits to configure. With QLDB, you only pay for what you use.

Amazon QLDB is available today in US East (Ohio), US East (N. Virginia), US West (Oregon), EU (Ireland), and Asia Pacific (Tokyo) regions, with additional regions coming soon.
