Answer: Utilize an Amazon DynamoDB table for session data storage., Employ an Amazon ElastiCache Redis cluster for session data.
For durable and efficient customer session management, storing session data in Amazon DynamoDB (Option B) and Amazon ElastiCache for Redis (Option D) are optimal solutions. DynamoDB offers a highly scalable and durable NoSQL database service, ensuring that session data remains consistent and available across multiple instances. ElastiCache for Redis provides an in-memory data store that can deliver fast access to session data with high throughput and low latency. Option A (Sticky sessions on ALB) does not provide durable storage as it is limited to the session duration and is not suitable for distributed systems. Option C (Amazon Cognito) is primarily for user authentication and management rather than session data storage. Option E (AWS Systems Manager) is not designed specifically for managing session information.
