Build a full$-$stack web application. Use free AWS cloud resources.

System design:

$-$ Responsive UI $($use React JS$)$ with a text input and a file input and submit button

$-$ Upload the input file to S$3$ from the browser directly $($do not send the file content directly to Lambda, do no get credentials from Cognito

$-$ Save the inputs and S$3$ path in DynamoDB FileTable via API gateway and Lambda Function. use auto$-$generated id via nanoid

$-$ After the file is uploaded in S$3$ and added to DynamoDB, trigger a script run in a VMinstance $($EC$2)$ via the DynamoDB event: $1.$ Create a new VM automatically. $2.$ Downlaod the script from S$3$ to the VM $($Upload the scripts to S$3$ via CDK or programatically as the InputFile$).3.$ Run the script in the VM$.4.$ Terminate the VM automatically.

Basic Requirements:

$-$ Use AWS CDK to manage AWS infrastructure

$-$ USE AWS SDK JavaScript V$3$ for Lambda

$-$ Do not put any AWS access key $/$ credentials in the code

$-$ No SSH and no hard$-$coded parameters

$-$ Txt file in S$3$ is not public. One user, one bucket. No shared bucket.

$-$ Do not use any AWS amplify front end or backend resource

$-$ After saving the inputs and S$3$ path in DynamoDB FileTabel, your system will create a new VM based on the event $($not a pre$-$provisioned VM$)$ and trigger the script to run automatiicaly with error handling $($no sleep$)$
