The IT team for an online retailer needs to ensure that the company's website remains operational, even in the event of a data center outage. To maximize uptime and maintain customer service continuity, what architecture should they implement?
Setting up all infrastructure within a single facility and scaling resources based on demand variability.
Locating all infrastructure in one facility while maintaining frequent data backups to a storage service for recovery purposes.
Spreading infrastructure across different facilities within the same vicinity but without specific isolation provisions.
Distributing the workload across geographically isolated facilities offered by the cloud provider to ensure operational resilience in the face of facility outages.
