Web3 Decentralized Applications on AWS Diagram

1. The browser makes a requests to the Amazon CloudFront domain, routed to the closest distribution for the Decentralized Application (DApp).

2. The DApp is cached at the edge in CloudFront. The DApp files are distributed to the edge by a CloudFront distribution that makes a request to an Amazon Simple Storage Service (Amazon S3) bucket, where the DApp files are statically hosted.

   The Amazon S3 bucket is secured by blocking all traffic except for a configured origin Access Identity of the CloudFront Distribution. Refer to Restricting access to an Amazon S3 origin.

3. The DApp makes requests to the Amazon API Gateway from the browser.

4. All requests to the API Gateway are sent to the AWS Lambda DApp Backend. It reads the path and method requests and binds them into a Web3.js request with a sigv4 signed Http Request Provider.

5. Amazon Managed Blockchain Ethereum Node receives and processes Web3 requests.

6. Ethereum requests and transactions are propagated to and received from the decentralized Ethereum Blockchain Mainnet.
