AWS Discontinues Amazon Quantum Ledger Database (QLDB)
InfoQ Homepage News AWS Discontinues Amazon Quantum Ledger Database (QLDB)
AWS recently announced that new customers can no longer sign up for Amazon Quantum Ledger Database (QLDB), a managed service providing an immutable transaction log maintained by a central trusted authority. All existing databases will be shut down in one year, and current users are encouraged to migrate to Aurora PostgreSQL.
Even though no formal announcements were made, the cloud provider updated their documentation and sent an email to existing customers, highlighting that support for QLDB will end on July 31, 2025.
First announced at re:Invent 2018, QLDB was initially available in preview form and became generally available in 2019. The ledger database provides a complete and cryptographically verifiable history of all changes made to application data. At the time, Jeff Barr, vice president and chief evangelist at AWS, wrote:
These features make QLDB a great fit for banking & finance, e-commerce, transportation & logistics, HR & payroll, manufacturing, and government applications, and many other use cases that need to maintain the integrity and history of stored data.
