The Poor Man's Multi-Cloud Fabric: Slashing Egress Bills with Mesh Tunneling in 2026
IT InstaTunnel Team Published by our engineering team The Poor Man’s Multi-Cloud Fabric: Slashing Egress Bills with Mesh Tunneling in 2026 Cloud providers have turned data egress into one of the most effective lock-in mechanisms in the history of enterprise software. The math is deliberately punishing: as of 2026, AWS charges $0.09 per GB for standard internet egress, Azure charges $0.087 per GB, and GCP charges $0.12 per GB for the first terabyte—with GCP doubling its CDN Interconnect and peering rates in North America effective May 1, 2026. A 2025 CloudZero analysis found that data transfer accounts for 6–12% of typical cloud bills, yet most engineering teams can’t identify where their egress spend is concentrated until it becomes a crisis. At 100 TB sitting on AWS, just moving it somewhere else costs $8,700 in egress before your new provider earns a dollar from you. There is a way out. By building a peer-to-peer encrypted mesh network across clouds, engineering teams can route...
