Explanation
Cloudwatch is a monitoring tool and is not used for session management.
In addition, S3 is a cloud storage, so it is not suitable for applications that require high-speed access such as session management.
For session management in AWS, DynamoDB, ElastiCache, or both are commonly used. DynamoDB is a key-value format database and delivers performance in the millisecond range, regardless of size.
ElastiCache is an in-memory data and provides high throughput and low latency.
