A retail software company wants to maintain functionality for users if one data center experiences a power failure. The company plans to replicate its environment across multiple designated areas. Which method best reduces exposure to local outages?
Use bigger compute nodes in one zone to handle loads during outages
Add a load balancer for a single cluster to shuffle requests among local nodes
Distribute services across multiple isolated areas, enabling failover between sites
Rely on a single zone with multiple duplicate servers deployed locally
Placing services in more than one location ensures that, if one site experiences a major issue like a power failure, another site can continue operations. Concentrating all systems in one zone, or using only local balancing, often leaves the application vulnerable if that location goes offline.
