A financial services company wants to ensure its critical customer-facing web application is always accessible and performs well, even during periods of high user activity. The primary goals are to prevent any single server failure from causing an outage and to efficiently distribute incoming user requests across the server farm. Which of the following solutions BEST meets both of these requirements?
A single, powerful server with virtualization enabled.
Deploying a software-defined wide area network (SD-WAN).
The best solution is to use a failover cluster combined with a load balancer. A failover cluster, a type of high-availability cluster, ensures service continuity by having redundant servers ready to take over if one fails. A load balancer distributes incoming traffic across the active servers in the cluster, which improves performance and responsiveness. While often used together, virtualization alone on a single server still represents a single point of failure. RAID provides storage redundancy but does not ensure service availability or distribute traffic. SD-WAN is a networking solution for managing WAN connections and is not the primary tool for application-level high availability.
