Ambient Mesh for Agentic Workloads and AI Growth
As organizations double down on distributed AI and agent-based workloads, old infrastructure models can’t keep pace. Traditional sidecar-based service mesh deployments are complex and costly to maintain, undermining the agility, scalability, and visibility that modern organizations demand.
AI Workloads and Agentic Architectures are Scaling. Fast.
By 2026, over 75% of large enterprises will run containerized AI workloads in production according to Gartner. Yet the complexities of managing secure, observable and scalable microservices remains a top barrier to digital innovation. New mesh patterns, like Ambient Mesh, are critical in enabling enterprises to manage AI workloads today and into the future.
Ambient Mesh: A Primer
Ambient Mesh is the latest evolution in service mesh technology within the Istio project. Unlike sidecar models which require a proxy alongside every pod, Ambient Mesh introduces a sidecarless approach that splits between a shared L4 proxy and optional L7 proxies:
- Node-level (ztunnel) proxies offer always-on mTLS and baseline security. The secure ztunnel proxy can be shared across all workloads on a node.
- Layer 7 (L7) waypoint proxies are deployed only where advanced routing or policy is needed, avoiding latency overhead.
For AI and agentic workloads, Ambient mesh eliminates redundant proxy overhead, reduces operational friction and supports rapid onboarding.

AI & Agentic Workloads Have Unique Demands
Agentic systems and AI microservices pose unique challenges:
- Agile scaling: Agents and models spin up and down rapidly. The operational burdens of managing static sidecars can limit agility.
- Observability at scale: AI pipelines and agentic interactions generate vast, complex traffic.
- Secure autonomy: Each agent must communicate securely, but not at the cost of developer velocity.
Ambient Mesh is built to support those demands, providing IT organizations with:
- Cost savings: Reduces infrastructure costs by up to 90%+. Calculate your potential savings using our Cost Savings Calculator.
- Operational simplicity: No app code changes or pod restarts - simply label a namespace and workloads join the mesh.
- Zero trust by default: Always-on encryption and fine-grained access controls to bolster security.
- Improved performance: A streamlined data plane provides better network performance and reduced latency, especially for workloads that don’t require Layer 7 processing.
5 Steps to Deploy Ambient Mesh for AI & Agentic Workloads
- Assess and Plan Migration
- Inventory your workloads: Identify which workloads require L7 features (e.g. AI inference and API gateways) and which workloads can operate at L4.
- Review production deployment best practices to anticipate mesh stability, upgrade and monitoring needs.
- Install Istio Ambient Mesh
- Deploy ztunnel proxies at the node level. This secures all L4 traffic via mTLS without sidecars.
- For AI-specific workloads, consider deploying Gloo Mesh for centralized control and multi-cluster management.
- Incrementally Onboard Services
- Label namespaces to join the mesh—no restarts or refactoring needed for most agentic workloads.
- For advanced L7 routing (e.g., model selection, traffic splitting), deploy waypoint proxies only where required.
- Secure, Monitor and Observe
- Leverage open source tools for policy enforcement and telemetry.
- Use Gloo Edge health checks and configuration validation for operational assurance.
- Scale and Automate
- Manage policies, upgrades, and mesh operations centrally to supportmulti-cloud, multi-region AI and agentic workloads.
- GitOps workflows and CI/CD tools can streamline deployment and mesh governance.

Advanced Tips: Integration and Scaling for AI and Agentic Ecosystems
- Smart Routing for AI: Integrate the Gateway API Inference Extension for dynamic LLM or agent routing.
- Policy Automation: Implement Open Policy Agent for fleet-wide AI policy governance.
- Observability at Scale: Use distributed tracing and telemetry pipelines for agentic workload visibility.
- Hybrid/Multicloud: Deploy Gloo Mesh to manage distributed clusters and multi-cloud AI services from a single pane.
Conclusion
Ambient Mesh unlocks secure, agile and cost-effective AI and agentic workloads for the enterprise while eliminating operational complexity, enabling IT organizations to focus on creating valuable business outcomes. With its proven cost savings, operational simplicity and zero-trust security, Ambient Mesh is the clear choice for enterprises seeking to future-proof their platform strategy.
