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.
Distributing the workload across geographically isolated facilities offered by the cloud provider to ensure operational resilience in the face of facility outages.
Spreading infrastructure across different facilities within the same vicinity but without specific isolation provisions.
Locating all infrastructure in one facility while maintaining frequent data backups to a storage service for recovery purposes.
To maximize uptime and continuity, the online retailer should distribute their workload across multiple geographically dispersed facilities within a cloud provider's infrastructure, known as Availability Zones. These zones are isolated locations within a region, which provides redundancy and fault tolerance. By adopting such an architecture, the retailer's website can withstand the loss of an entire facility without significant disruption to the customer experience. The incorrect answer choices suggest less resilient methods that could result in substantial downtime: utilizing a single facility does not protect against its potential failure, regular data backups do not prevent service outages, and spreading infrastructure without the geographic dispersion and independence offered by distinct zones fails to safeguard against localized incidents.
