Description

Two of the most challenging requirements of VPNs are high availability and high performance. High availability ensures continuous operation even if one or more VPN servers fail. High performance enhancements are deployed to boost the system performance by alleviating the load that is placed on a single VPN server. This course discusses the methods of deploying high availability: redundant peering, active/standby failover, cluster load balancing, and server load balancing (SLB). This course explains the troubleshooting methods that can be employed to investigate high availability problems.
