Topic 1 Question 49
An online retail company based in the United States plans to expand its operations to Europe and Asia in the next six months. Its product currently runs on Amazon EC2 instances behind an Application Load Balancer. The instances run in an Amazon EC2 Auto Scaling group across multiple Availability Zones. All data is stored in an Amazon Aurora database instance. When the product is deployed in multiple regions, the company wants a single product catalog across all regions, but for compliance purposes, its customer information and purchases must be kept in each region. How should the company meet these requirements with the LEAST amount of application changes?
Use Amazon Redshift for the product catalog and Amazon DynamoDB tables for the customer information and purchases.
Use Amazon DynamoDB global tables for the product catalog and regional tables for the customer information and purchases.
Use Aurora with read replicas for the product catalog and additional local Aurora instances in each region for the customer information and purchases.
Use Aurora for the product catalog and Amazon DynamoDB global tables for the customer information and purchases.

The best solution to meet the company's requirements with the LEAST amount of application changes is to use Aurora with read replicas for the product catalog and additional local Aurora instances in each region for the customer information and purchases. This will allow for a single product catalog across all regions, while still keeping customer information and purchases in each region for compliance purposes. Amazon Redshift is a data warehousing solution and is not appropriate for this use case. Amazon DynamoDB global tables may be used, but they require application changes to support them. Using local Aurora instances in each region for customer information and purchases could also work, but this would require more configuration and management than using Aurora with read replicas. Therefore, option C is the best solution.

C. Using Aurora with read replicas for the product catalog allows for a single product catalog across all regions. Aurora read replicas can be set up in different regions to provide low-latency access to the product catalog from each region. Additionally, by deploying additional local Aurora instances in each region for customer information and purchases, the company can comply with the requirement of keeping customer data and purchases in each region.
