A license portal still stores session files and uploads on a single instance’s local disk, so any instance death loses state. How should the architect redesign for distributed resilience?
Select an answer to reveal the explanation.
Short Explanation
Local disk is a backpack chained to one runner—when that runner falls, the bag is gone. Park shared files on EFS, S3, or a DB so any web box can vanish. Bigger local disks just make a heavier backpack.
Full Explanation
Distributed resilient designs avoid instance-local single points of failure for shared state. Placing files and durable data on Amazon EFS, Amazon S3, or a managed database lets Auto Scaling replace instances without data loss. Larger local disks, RAID on instance store, and permanent sticky sessions do not eliminate the SPOF; they prolong dependence on one host. Stateless or externally stateful compute is a core HA pattern.
