A company is planning to migrate its on-premises application to AWS. The application's database stores both structured product data and temporary user session data. To enhance performance and ensure disaster recovery, the company requires a solution that effectively decouples the product data from the user session data and supports replication in another AWS Region. Which AWS service configuration would provide the highest performance for this scenario?
Explanation:
Option C is the correct answer. Amazon DynamoDB is highly suitable for storing both structured product data and temporary user session data. By utilizing two separate DynamoDB global tables, one for product data and one for user session data, the company can effectively decouple these datasets. Additionally, integrating DynamoDB Accelerator (DAX) provides in-memory caching, which significantly enhances query performance. This setup ensures high availability and lower latency, making it an optimal solution for the given requirements.
