Why each option
Deploying two NetScaler appliances across primary and secondary data centers with a backup vServer ensures high availability and disaster recovery, while strategically managing network traffic. This configuration provides redundancy for critical services and optimizes the flow of external WAN traffic by directing users to the appropriate data center.
While secure and reliable connections are a NetScaler benefit, 'cost-effective' is not a guaranteed primary outcome for this specific configuration, and it does not fully explain the technical advantages of a backup vServer.
A backup vServer configuration on NetScaler appliances, when deployed across two data centers, inherently provides redundancy by allowing one vServer to take over if the primary fails. This multi-datacenter setup also optimizes external WAN traffic by potentially directing users to the closest or most available data center, reducing latency and bandwidth consumption across distant links.
This configuration focuses on disaster recovery and traffic optimization, not on segmenting NetScaler Gateway and load-balancing features.
While NetScaler provides SSL VPN, this specific design is primarily about redundancy and traffic management through a backup vServer, not solely about expanding remote access or providing basic SSL VPN.
