I've been tasked to explore options for reducing my company's datacenter footprint or going completely to cloud, and one of the thorny DC functions that I'm having a hard time cloudifying is internet egress. It doesn't look like sending general corporate traffic out through AWS would be cost effective due to volume based fees, Cisco Cloud Web Security and similar services all have way too many horror stories, and relying on a carrier for MPLS-based egress e.g. AT&T "network-based firewall" seems like an even less attractive option.
Does anyone have a cloud-based alternative that they're happy with to the classic on-premise internet egress model of backhauling traffic to a physical datacenter and passing through an on-prem security stack?
