This means that VPN head-ends will be dispersed across both private and public clouds.Īgain, AI will likely play a role in determining the optimal path to a specific file, application or service. Legacy client VPNs will also likely be rearchitected in the future to better handle data flows within hybrid cloud environments. Consider new advancements and architectures If a remote resource is needed that requires a client VPN tunnel to be established, the AI automatically builds it in the background - completely transparent from an end-user perspective. The VPN software will be able to monitor what apps and services the user is accessing. For one, as automation and AI creep into business apps and services, the same will happen with client VPN technologies. That logically brings us to what must happen with today's client VPN products to make them more user-friendly and flexible from a hybrid cloud architecture perspective. Thus, the need for a client-based VPN architecture still remains today - and will likely remain well into the future. The concept of using application-based SSL certificates cannot be used in all situations. While client VPNs haven't kept up with major shifts in enterprise technologies, I wouldn't fully count them out. Additionally, many legacy apps still require a fat client as opposed to a web-based interface. While more data and apps are moving into a public cloud, many critical services remain on premises. Still relevant, but innovation neededĬlient VPN technologies are still important because most businesses have taken a hybrid cloud approach. Yet, client VPN is still necessary for legitimate reasons, and a few architectural changes could eliminate most of the problems found in traditional architectures. Thus, having to backhaul all data to a corporate office only to hairpin and go back out to the internet to access public cloud resources can produce added network latency and traffic bottlenecks.įor these reasons, many technology pundits are pronouncing the eventual end of client VPN technologies. Instead, most client VPNs still terminate at the corporate internet edge, despite the distinct possibility that a large chunk of data and apps now reside in the public cloud. This includes software installs, configurations and operating the software to bring the tunnel up and down as needed.Īdditionally, the overall VPN architecture hasn't changed to meet the emerging trends of public cloud use and mobile workforces. The tunnel prevents the data from being read or tampered with.ĭespite the shift from fat client VPN applications to Secure Sockets Layer ( SSL) thin clients, administrators and end users must perform multiple manual steps for proper operation. The purpose of a VPN is to pipe data through an encrypted tunnel that connects trusted devices across one or more untrusted networks.
