Amazon Web Services, Inc. (AWS), an Amazon company (AMZN) has announced the general availability of Amazon QLDB i.e Quantum Ledger Database. The fully-managed service provides a high-performance, immutable, and cryptographically verifiable ledger for applications that need a central trusted authority.
As Amazon QLDB is a centralized service, customers can use it to maintain permanent records of transactions. Also, they can use it for keeping a track of credit and debit transactions across customer bank accounts or to track the manufacturing history of a product. According to Amazon, the service is easy to use, because of its familiar database capabilities. It also allows customers the advantage of storing structured or unstructured data. Unlike the ledgers in common blockchain frameworks, this service does not require distributed consensus. Thus it can execute two to three times as many transactions at the same time as common blockchain frameworks. There are no upfront commitments to use Amazon QLDB. Thus, customers pay for what they use.
The customers and partners who are already using this Amazon service include Splunk, Klarna Bank, Driver, and Vehicle Licensing Agency and Accenture. Amazon QLDB is now available in the US East (Ohio), US East (N. Virginia), US West (Oregon), Asia Pacific (Tokyo) and EU (Ireland). Some additional regions will be coming soon as per the source.
