As organizations migrate their business applications to colocation centers and XaaS providers, and after the last internal resource is moved to the cloud, what is the point of remote access? Remote access to what?
If we think about this in terms of VPN and the protection afforded through encryption, VPN still makes good business sense for the purpose protecting net-work traffic from potential eavesdroppers (whether the human or malware variety). For this reason, it’s preferred to say “VPN” instead of saying “remote access.”
Organizations still need to address several subtopics when considering their VPN architectures in light of cloud migration, such as split tunneling, Internet backhaul-ing, and whether VPN should always automatically activate on workstations away from internal corporate networks.
