Google Cloud Next '26: Agent Gateway Seizes Control Plane, TPU 8i Locks Inference
Summary
Key Takeaways
Google Cloud Next '26 unveils a vertically integrated stack for the Agentic Enterprise.
AI Infrastructure: 8th-gen TPUs—TPU 8t for training, TPU 8i for near-zero latency inference—backed by Managed Lustre (10 TB/s throughput) and Virgo Networking.
Agent Platform: Built on Vertex AI, featuring Agent Studio (low-code), Agent Registry (unified discovery), Agent Identity (cryptographic ID and policies), Agent Gateway (centralized policy enforcement with MCP/A2A protocol support), Agent-to-Agent Orchestration (generative/deterministic), and Agent Observability (OTel-compliant). Agent Designer enables no-code trigger-based agents; Long-running agents execute multi-step workflows in secure sandboxes.
Agentic Data Cloud: Cross-cloud Lakehouse and Knowledge Catalog. Agentic Defense: Integrates Google Threat Intelligence and Wiz for AI-APP protection from code to runtime.
Why It Matters
Beneath the agent platform gloss, Google is executing a control plane shift: Agent Gateway and Agent Registry become the sole arbiters of all agent interactions. Every cross-agent call, even to third-party models like Anthropic, must pass through Gateway, enabling policy enforcement, telemetry collection, and eventual lock-in to Agent Identity and Agent Observability.
Hidden lock-in: Agent Identity ties each agent to Google Cloud IAM; Agent Gateway as single policy enforcement point makes multi-cloud migration prohibitively expensive—all trust relationships and routing rules depend on Google's orchestration layer.
Physical limits: TPU 8i 'near-zero latency' inference relies on Virgo Networking and Managed Lustre's proprietary topology. Cross-cloud agent communication must traverse Google Gateway, adding latency and egress costs. Agent-to-Agent Orchestration's generative mode may cause tail latency and PFC/ECN bottlenecks under massive agent swarms due to centralized Gateway decision-making. Agent Simulation and Agent Evaluation force users into Google's monitoring loop, blocking third-party observability tools like Datadog or Grafana.
PRO Decision
【Vendors】 AWS and Microsoft Azure should launch an open agent orchestration standard (e.g., Kubernetes-based) to counter Google's Agent Gateway lock-in. Attack Agent Identity's tight coupling with Google IAM by offering cross-cloud agent identity federation. Nvidia should highlight GPU+DPU flexibility vs TPU 8i's performance degradation outside Google's network.
【Enterprises】 CIOs must conduct zero-trust technical audits: demand independent benchmarks for Agent Gateway latency/throughput in multi-cloud scenarios. Verify Agent Identity supports external IdPs (Okta, Azure AD) to avoid IAM lock-in. Require Agent Observability to output standard OpenTelemetry for portability. Maintain at least one open-source agent framework (LangGraph, CrewAI) as fallback.
【Investors】 See through the PR: Google Cloud uses Agent Platform to shift AI workloads from GPUs to its own TPUs, bundling security (Wiz) and storage (Managed Lustre) to boost ARPU. Vendor concentration risk is extreme—once enterprises adopt Agent Gateway, switching cloud providers becomes costlier than traditional IaaS migration. Monitor whether Google's Agent Platform customer growth outpaces open alternatives, and watch for control plane lock-in eroding enterprise bargaining power.
