This analysis of our Q4 results and our guidance for Q1 2026 is based on non-GAAP and excludes all non-cash stock-based compensation impacts, certain acquisition-required charges, and other non-recurring items. A full reconciliation of our selected GAAP to non-GAAP results is provided in our earnings release. International growth was a good milestone in both Asia and Europe, growing north of 40% annually. Shifting to annual customer sector revenue for 2025, cloud and AI titans contributed significantly at 48%.
With our increased visibility, we are now doubling from 2025 to 2026 to $3.25 billion in AI networking revenue. Together with our recent VeloCloud acquisition in July 2025, we are driving that homogeneous, secure client to branch to campus solution with unified management domains. We have also successfully deployed in many routing edge, core spine, and peering use cases. The combined campus and routing adjacencies together contribute approximately 18% of revenue.
Our third and final category is the network software and services based on subscription models such as A-Care, CloudVision, Observability, Advanced Security, and even some branch edge services. We added another 350 CloudVision customers a day, almost 1 new customer a day, and deployed an aggregate of 3,000 customers with CloudVision over the past decade. Arista's subscription-based network services and software revenue contributed approximately 17%, and please note that it does not include perpetual software licenses that are otherwise included in core or adjacent markets. We are becoming the preferred network innovator of choice for client to cloud and AI networking, with a highly differentiated software stack and a uniform CloudVision software foundation.
