AWS Dives into Blockchain with Two New Services
by Josh Anderson
LAS VEGAS, NV — A year after Andy Jassy, CEO of AWS remarked that he had no interest in pursuing any Blockchain-based platforms, his company made a stark turn around and introduced a pair of Blockchain-based services at AWS re-Invent 2018 in Las Vegas.
First up, the Quantum Ledger Database (QLDB) is a centrally managed system to track each and every data change in an application. Interestingly, the ledger does not require a decentralized infrastructure like other Blockchain-based frameworks, but it does boast a strong degree of immutability. Secondly, Amazon Managed Service will provide users with access to open-source Ethereum and Hyperledger Fabric frameworks for the creation and management of Blockchain-based networks.
“Amazon Managed Blockchain is a fully managed service that allows you to set up and manage a scalable blockchain network with just a few clicks. Amazon Managed Blockchain eliminates the overhead required to create the network, and automatically scales to meet the demands of thousands of applications running millions of transactions,” reads the official product page on the AWS website. “
“Once your network is up and running, Managed Blockchain makes it easy to manage and maintain your blockchain network. It manages your certificates, lets you easily invite new members to join the network, and tracks operational metrics such as usage of compute, memory, and storage resources. In addition, Managed Blockchain can replicate an immutable copy of your blockchain network activity into Amazon Quantum Ledger Database (QLDB), a fully managed ledger database. This allows you to easily analyze the network activity outside the network and gain insights into trends.”
“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. 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,” AWS writes on that specific product page.
“QLDB uses an immutable transactional 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.”
