Deploy the Solution

This project is built using the AWS Cloud Development Kit (CDK). The following versions of Node.js and AWS CDK have been used:

• Node.js: v20.16.0
• AWS CDK: 2.143.0

To install a specific version of AWS CDK, run the following command:

npm install -g aws-cdk@X.YY.Z

Follow these steps to deploy the solution:

1. Clone this repository:

   git clone https://github.com/aws-samples/DigiDhan-GenAI-FSI-LendingSolution-India.git

2. Enter the code sample backend directory:

   cd DigiDhan-GenAI-FSI-LendingSolution-India/

3. Install packages:

   npm install
   npm install -g aws-cdk

4. Bootstrap AWS CDK resources on the AWS account. If deployed in any region other than us-east-1, the stack may fail due to the lambda layers dependency. You can either comment out the layer and deploy in another region or deploy in us-east-1:

   cdk bootstrap aws://ACCOUNT_ID/REGION

5. Enable access to Amazon Bedrock Models. You must explicitly enable access to models before they can be used with the Amazon Bedrock service. Follow these steps in the Amazon Bedrock User Guide to enable access to the models (Anthropic::Claude (Sonnet) and Cohere::Embed English).

6. Deploy the sample in your account:

   cdk deploy --all

   This command will deploy one stack in your account. The AWS CDK Toolkit will prompt you to approve security-related changes before deploying them. You will need to answer "yes" to get all the stacks deployed.

   Note: The IAM role creation in this example is for illustration only. Always provision IAM roles with the least required privileges. The stack deployment takes approximately 10-15 minutes. Once the stack is successfully deployed, you can find the InsureAssistApiAlbDnsName in the output section of the stack, which is the application endpoint.

Post Deployment Actions

1. Go to the Bedrock console in the deployed region and edit the Agent. Modify additional settings and enable user Input, which decides whether the agent can prompt additional information from the user when it does not have enough information to respond to an utterance.

   

Architecture

Clean up

To avoid unexpected charges, do not forget to delete the stack. First, make sure to remove all data from the Amazon Simple Storage Service (Amazon S3) Bucket, then run the following command:

cdk destroy
