Leveraging over 25 years of network innovation powering services like Search and YouTube, Google Cloud now offers its planet-scale backbone network (202 PoPs, 2M+ miles fiber, 99.99% SLA) to enterprises via the new Cloud WAN. This fully managed service addresses the complexities and fragmented security of traditional WANs, which are further strained by the demands of modern cloud applications and the rapid emergence of AI. Cloud WAN provides a unified, secure, and reliable solution offering up to 40% faster performance than the public internet and up to 40% TCO savings over customer-managed WANs. It supports key use cases including high-performance cross-region connectivity (via Cloud Interconnect, Cross-Cloud Interconnect, and the new Cross-Site L2 Interconnect) and modernized branch/campus networking leveraging Google's Premium Tier network and Network Connectivity Center (NCC). With an open ecosystem integrating leading SD-WAN, SSE (e.g., Palo Alto Networks, Broadcom), NGFW, and specialized partners like Juniper Mist (for AI-driven branch transformation) and Infoblox (for DDI), Cloud WAN delivers the performance, scalability, security, and cost-effectiveness required for businesses navigating the AI era.
