realtime sync of files between instances
In my implementation, I have a java app that reads/writes files into local storage. Since the same java app will be running across multiple instances in AWS, i need to sync these files (created/updated by the java app) across all instances in realtime. Is this possible, if not, any alternative to achieve the goal?
