Implementing A High Availability VPN

Virtual Private Networks (VPNs) are becoming essential business tools allowing mobile and remote workers to access their email, files, and applications. This increased reliance on access to business information poses a significant risk for businesses everywhere should a VPN system fail.

VPN system crashes can be caused by VPN hardware failure or communication connection failure. Since organizations may have little or no control over how long it takes to resolve problems, a good approach is to ensure that the VPN can be restored as soon as a component fails by implementing a high availability VPN can.

The normal method of implementing a high availability VPN is to purchase two VPN hardware modules and configure them as a high availability pair using vendor-provided technology or a third-party solution. With this approach, if one device fails, another device becomes available to provide VPN service.

Using different suppliers eliminates the risk of one operator having an error affecting each circuit. If the connection fails, the remote user will have to reconnect using the new scheme. Reconnecting is usually done by users who have opted for an alternative VPN server. Another strategy is to implement multiplied internet routes to the VPN server, although it is a much more complex approach.

When considering a highly cost-effective VPN solution, consider all factors, including the complexity of deployment and management, fault-tolerant visibility for remote users, and the cost each solution can generate in the long run.
