Hi Team

I have a requirement to integration Amazon Kendra Search solution with AEM as a cloud. I have seen the documentation on Amazon however would want to know inputs if anyone integrated recently.

 

Basically to start with I want to do POC on AEM local cloud sdk.

 

Any pointers would be really helpful.

 

Thanks in advance.

Hi @prashardan,

1. Create Amazon Kendra Index

  • Go to AWS Console > Amazon Kendra

  • Create an Index and note down the Index ID

Reference: https://docs.aws.amazon.com/kendra/latest/dg/getting-started.html

2. Add AWS SDK Dependency in core/pom.xml

<dependency> <groupId>software.amazon.awssdk</groupId> <artifactId>kendra</artifactId> <version>2.25.14</version> </dependency>

Reference: https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/kendra/KendraClient.html
3. Create Sling Servlet to Query Kendra

Use KendraClient in a servlet to query based on user input.

Basic steps:

  • Read query param

  • Call KendraClient.query(...)

  • Parse results and return JSON

4. Test Endpoint

Access your servlet via:

http://localhost:4502/bin/kendra/search?q=your+query

5. Security Note

For local, use AWS credentials via ~/.aws/credentials.

Reference: https://docs.aws.amazon.com/sdk-for-java/latest/developer-guide/credentials.html

Hi @prashardan ,

 

Steps for POC:

  1. Set up a Kendra index in AWS.

  2. Push AEM content (pages or fragments) to Kendra using its API or connector.

  3. Build a search UI in AEM that sends queries to Kendra and shows results.

  4. Handle authentication using AWS IAM or API keys.

 

Thanks & Regards,

Vishal

    @santoshsai @vishalka5 @prashardan 
    For our local setup, we're currently using AWS session credentials for the POC.
    From a security and authentication standpoint, do you have any recommendations or best practices for establishing a secure connection between the application and AEM Cloud using the AWS SDK? Specifically, what would be the suggested approach at the application level, and how should we proceed to ensure a secure and scalable integration

    I would suggest:

    • Use IAM Role with Web Identity (Recommended)

      • Use AWS STS (AssumeRoleWithWebIdentity) to get temporary credentials securely.

      • No hardcoded credentials in AEM.

    • Use Environment Variables / Secrets Manager

      • Store role ARN and config securely.

      • Never embed secrets in code.

    • Least Privilege IAM Policy

      • Grant only kendra:Query and needed actions to the IAM role.
