A. Create a DynamoDB table for each tenant by using the tenant ID in the table name. Create a service that uses the JWT token to retrieve the appropriate Lambda execution role that is tenant-specific. Attach IAM policies to the execution role to allow access only to the DynamoDB table for the tenant.
B. Add tenant ID information to the partition key of the DynamoDB table. Create a service that uses the JWT token to retrieve the appropriate Lambda execution role that is tenant-specific. Attach IAM policies to the execution role to allow access to items in the table only when the key matches the tenant ID.
C. Create a separate AWS account for each tenant of the application. Use dedicated infrastructure for each tenant. Ensure that no cross-account network connectivity exists.
D. Add tenant ID as a sort key in every DynamoDB table. Add logic to each Lambda function to use the tenant ID that comes from the JWT token as the sort key in every operation on the DynamoDB table.
