A company has a serverless multi-tenant content management system on AWS. The architecture contains a web-based front end that interacts with an Amazon API Gateway API that uses a custom AWS Lambda authorizer. The authorizer authenticates a user to its tenant ID and encodes the information in a JSON Web Token (JWT) token. After authentication, each API call through API Gateway targets a Lambda function that interacts with a single Amazon DynamoDB table to fulfill requests. To comply with security standards, the company needs a stronger isolation between tenants. The company will have hundreds of customers within the first year. Which solution will meet these requirements with the LEAST operational overhead?
