VPN (virtual private networks) are invaluable network links that allow your important customers and associates to access your network from outside. While an intelligently designed VPN offers security, reliability and performance, ensuring that your VPN is up and running at all times is critical. In some of the better VPN redundancy systems, platforms utilize automatic failover/failback systems to ensure that remote users stay connected, reducing loss of productivity and significantly minimizing network outage.
Another system that is utilized on better VPN redundancy platforms is fully meshed resiliency. With a fully meshed resiliency platform, even two possible outages occurring simultaneously won’t be able to keep your VPN offline. The design of the system keeps your network up and running.
Flexible site2site deployments are also a feature of high quality VPN redundant networks. Site2site tunnels can increase performance on VPN networks when only a single site has multiple WAN connections. This technology utilizes multiple paths, TCP optimization, and compression to increase overall performance and responsiveness.
While VPN redundancy will ensure that your network stays up, active and easy to access with a good platform you can also reduce your connectivity costs. Obviously, for many enterprises and businesses cost is an issue, however, site2site technology, in addition to using low cost internet broadband connections can be extremely cost effective and you will receive lower costs while still receiving high quality access with built in reliability and redundancy.
Avoiding network outages keeps productivity high and is critical for all businesses and enterprises; this is why it is important to choose a VPN redundancy platform that is high quality and extremely responsive. Besides site2site VPN redundancy platforms, there are several technologies that are used that have disadvantages. One is WAN optimization. While WAN optimization can be helpful with certain issues (including download performance) they ultimately lack performance and are sometimes choppy when using small files and non-reoccurring data structures.
Another technology that is used with for VPN redundancy, but fails to be a comprehensive solution is expensive MPLS links. MPLS links are great for providing users with a high degree of control over their applications across a network, however, in order to realize its full potential, extensive upgrades need to occur, as well as high bandwidth costs. Many enterprises and businesses can get the same or higher performance simply by adding a simple broadband connection to existing MPLS networks. This still gives users a high degree of control over applications on their networks, but also increases speed and performance.
