Using AWS Client VPN to scale your work from home capacity
Traditional on-premises VPN services are fixed in capacity and difficult to scale up, or down, in a rapid and on-demand fashion. Hardware constraints, licensing, and bandwidth can all be factors that prevent traditional client VPN services from scaling to meet the needs of a rapidly growing mobile workforce. Fortunately, the elasticity of cloud and pay-as-you-go […]
