❓ Frequently Asked Questions
What is the primary difference between AppStream 2.0 and Amazon WorkSpaces?
AppStream 2.0 is designed for streaming specific applications on a non-persistent basis, whereas WorkSpaces provides a persistent, full virtual desktop environment for a dedicated user's daily work.
How do users save their data since the service is non-persistent?
Because AppStream 2.0 instances are wiped after each session, users must integrate external storage solutions like Amazon S3 or Home Folders to ensure their files are persisted.
