Container data can be lost unless stored in persistent volumes.

A single component's failure can take down your entire application, even with redundancy.

Containers share the host OS kernel, while VMs virtualize hardware with separate OS.

Availability Zones help prevent downtime by isolating failures across multiple locations.

Fault domains help prevent multiple servers from failing together in an architecture.

RPO and RTO are key metrics for planning disaster recovery strategies.

Disaster recovery ensures systems can restore services and data after major disruptions.

Global failover ensures applications remain available by redirecting traffic from failed regions to functioning ones.

Data residency is crucial for compliance with laws about where data can be stored.

Active-Active Architecture uses multiple regions to serve traffic simultaneously for better resilience.

Choosing between single and multi-region architecture affects system resilience and cost.
