One Network: Cloud-Agnostic Service and Policy-Oriented Network Architecture
Briefly

Google has developed over 300 cloud products but encounters challenges with integration and low developer velocity due to complex networking. The company’s cloud infrastructure involves multiple network paths running products like Borg and Cloud Run, each with its own networking layers. Managing policies for cloud infrastructure is crucial, as effective policy control is needed across all environments and products, necessitating a unified approach without additional modifications. Complications arise from various runtimes and infrastructures that applications utilize, requiring careful orchestration and management.
