A Google Cloud WAN is a cloud network infrastructure that enables enterprise organizations to access and leverage Google's global network for wide area network connectivity.

Context:
- It can typically provide High-Performance Cross-Region Connectivity through dedicated low-latency connections and private network infrastructure.
- It can typically deliver Enterprise Network Performance that is up to 40% faster than public internet connections.
- It can typically reduce Enterprise Network Cost by up to 40% compared to customer-managed WAN solutions.
- It can typically leverage Google's Global Network Infrastructure consisting of over 2 million miles of fiber optic cables, 33 subsea cables, and 202 point of presences worldwide.
- It can typically maintain a Network Reliability level with a 99.99% service-level agreement.
- It can typically support Cross-Cloud Connectivity between Google Cloud and other public cloud environments including AWS, Microsoft Azure, and Oracle Cloud Infrastructure.
- It can typically enable Branch Office Connectivity to cloud applications, SaaS applications, and the internet with built-in security and low latency.
- ...
- It can often simplify Enterprise WAN Management through centralized configuration and consolidated security stacks.
- It can often facilitate Global Data Transfer between geographically dispersed data centers in a reliable and cost-effective manner.
- It can often enhance Application Performance for enterprise workloads through optimized routing and reduced network hops.
- It can often support Multi-Cloud Strategy by providing consistent network experience across different cloud provider environments.
- ...
- It can range from being a Simple Branch Network Connectivity Solution to being a Complex Global Enterprise Backbone, depending on its deployment scale and organizational requirements.
- It can range from being a Regional Network Solution to being a Global Network Infrastructure, depending on its geographic coverage and connectivity requirements.
- ...
- It can have Cloud Interconnect for private dedicated connections between Google Cloud regions and on-premises data centers.
- It can have Cross-Cloud Interconnect for multi-cloud connectivity available in 21 global locations.
- It can have Cross-Site Interconnect for dedicated point-to-point layer 2 private connections at 10 Gbps or 100 Gbps connection speeds.
- It can have Network Connectivity Center for connecting branch offices using Cloud VPN or SD-WAN solutions.
- It can have Premium Tier Network for ensuring internet-based traffic enters and exits Google's network at the geographically closest point of presence.
- ...
Examples:
Counter-Examples:
- Traditional MPLS Network, which lacks integrated cloud connectivity and has higher total cost of ownership.
- Public Internet-Based SD-WAN, which lacks consistent performance guarantees and private network security.
- Cloud Provider Dedicated Interconnect, which lacks global network backbone access and multi-cloud integration capability.
- Customer-Managed WAN Solution, which requires significant infrastructure investment and complex network management.
