AWS Transit Gateway, Azure Virtual WAN, and GCP Network Connectivity Center are the three dominant cloud-native networking hubs — and every network engineer moving into multi-cloud needs to understand how they differ. Each implements a hub-and-spoke model familiar to anyone who has configured DMVPN or SD-WAN, but the BGP peering models, route propagation behavior, and Cisco SD-WAN integration points vary significantly across all three platforms. Key Takeaway: Cloud networking hubs are not interchangeable — AWS Transit Gateway gives you the most granular routing control, Azure Virtual WAN provides the best globally distributed managed hub, and GCP Network Connectivity Center leverages Google’s premium backbone for highest raw performance. Understanding all three is essential for any CCIE candidate working in multi-cloud environments. ...

Cloud networking fees are the fastest-growing line item on enterprise cloud bills in 2026, and most teams don’t see them coming. According to ByteIota (2026), networking-related charges — egress data transfer, public IPv4 addresses, and NAT Gateway processing — now represent an “hidden 18% tax” on total cloud spend for organizations running multi-cloud or hybrid architectures. Key Takeaway: If you’re a network engineer moving to the cloud with an on-prem mindset where bandwidth is essentially free, your architecture decisions could be costing your organization tens of thousands of dollars per month in avoidable networking fees. ...
