AWS Announces Blockchain Services
Amazon Web Services Inc. (AWS), announced two new services related to blockchain at its reInvent conference in Las Vegas.
Both services use blockchain technology. However, Amazon Quantum Ledger Database, (QLDB), requires the use of a trusted central administrator, while Amazon Managed Blockchain doesn’t.
According to the company, both services are used by companies to manage transactions that require auditability.
“Amazon QLDB” is a transparent, immutable and cryptographically verifyable ledger that can be used by applications that require a central, trusted authority to provide a permanent record of transactions (for instance, supply chain, financial manufacturing, insurance, or HR), the company stated in a news release on November 28. Amazon Managed Blockchain is a platform that allows customers to create applications that allow multiple parties to execute transactions without the need of a central authority. It uses the popular open-source Ethereum and Hyperledger Fabric frameworks to make it easy to manage scalable blockchain networks.
The QLDB offers a SQL-like API, which may be familiar to data developers. It does not require the user to manage or configure servers. It scales automatically to meet the application demand and charges only for what resources are used. Developers interested in the preview service can sign up here.
Amazon Managed Blockchain is also available in preview. AWS stated that Managed Blockchain manages your certificates and allows you to invite new members to the network. It also tracks operational metrics like compute, memory and storage usage. Managed Blockchain also allows you to replicate a copy of your blockchain network activity into Amazon Quantum Ledger Database, (QLDB), which is a fully managed ledger data base. This allows you to quickly analyze the network activity and gain insight into trends.
