A solutions architect is designing the architecture of a new application being deployed to the AWS Cloud. The application will run on Amazon EC2 On-Demand Instances and will automatically scale across multiple Availability Zones. The EC2 instances will scale up and down frequently throughout the day.

What should the solutions architect do to ensure that the architecture supports distributed session data management?

AUse Amazon ElastiCache to manage and store session data.

BUse session affinity (sticky sessions) of the ALB to manage session data.

CUse Session Manager from AWS Systems Manager to manage the session.

In order to address scalability and to provide a shared data storage for sessions that can be accessible from any individual web server, you can abstract the HTTP sessions from the web servers themselves. A common solution to for this is to leverage an In-Memory Key/Value store such as Redis and Memcached. ElastiCache offerings for In-Memory key/value stores include ElastiCache for Redis, which can support replication, and ElastiCache for Memcached which does not support replication.
