- 10. 10© 2018 PORTWORX with CODEFRESH Top Problems with Stateful Containers in Production 1. Stuck without HA: app wants to failover to new server but data is stuck/mounted to EBS/drive on the old server 2. Data protection: snapshot, back-up, and encryption are at the VM-level and not at the app level 3. No Performance Control: running multiple containers per server = poor performance EBSEBS EBS x86x86x86
