Amazon has provided templates for creating your own Blockchain.
In order to make it easier for customers to create blockchain applications based on Amazon Web services (AWS), the company introduced "AWS Blockchain Templates". They allow users to launch public and private networks based on Ethereum and Hyperledger Fabric in a few clicks.
For starters, you must choose AWS Blockchain template after you create a network on Ethereum. In their blog, Amazon noted that they want to simplify the creation of blockchain networks: "Let developers are engaged in the creation of blockchain applications, not manual network settings."
Also, the network will support Ethereum mining and you will have access to the EthStats page to monitor the state of the network. Also, you will have an EthExplorer tool that will allow users to view their transactions and smart contracts.
If it's that simple, will you create something of your own?
