When a new customer came to us with 8 offices across the country, 150 highly-skilled knowledge workers who were seldom in those offices, and high levels of dissatisfaction with VPNs and distributed file access, we knew the traditional approach to IT infrastructure had already proved to be unworkable. Using VPNs to access core business functions stuck on servers inside offices that hang off the Internet by a thread was never going to a good way to do things, and it never will be. Modern, distributed working patterns demand a different approach to the whole delivery structure connecting people with core business systems.
