Glossary
This glossary defines the key terms and concepts used throughout the Agentic Layer architecture documentation.
A
- A2A
-
Agent-to-Agent protocol. Used on the wire between agents within the Agent Runtime, and between external systems and the Agent Gateway.
- AG-UI
-
Application-to-agent UI protocol. Used by Apps to reach the Agent Gateway.
- Agent (CRD)
-
Kubernetes custom resource that declares a single agent workload. Reconciled by the Agent Runtime Operator into a
DeploymentandService. - Agent Gateway
-
Separate building block in front of the Agent Runtime. Translates external protocols (OpenAI Chat Completion API, A2A, AG-UI) into the internal A2A surface used by agents and routes requests to the appropriate agent. Defined by the
AgentGatewayandAgentGatewayClassCRDs. - Agent Runtime / Agent Orchestration
-
Kubernetes-native execution environment that hosts agents and manages their lifecycle. Reconciled by the Agent Runtime Operator, which groups the
Agent,AgenticWorkforce, andAgentRuntimeConfigurationCRDs and supports both template-based and custom-image agents on any framework that speaks A2A. - AgentGateway / AgentGatewayClass (CRDs)
-
The agent-gateway resource (an instance) and its pluggable class (selects an implementation). Together they define an Agent Gateway deployment.
- AgentRuntimeConfiguration (CRD)
-
Namespace-scoped, operator-wide runtime configuration for the Agent Runtime. One instance per operator namespace; carries defaults such as the default framework and template images.
- Agentic Layer
-
Platform layer containing the building blocks for AI agent orchestration: Agent Runtime, Agent Gateway, AI Gateway, Tool Gateway, Tool Servers, Guardrails, and Observability. Built on Kubernetes.
- Agentic Workforces
-
Application-level implementations of AI agent systems for specific enterprise use cases, such as Insurance Claims Processing, Healthcare Operations, or Procurement workflows.
- AgenticWorkforce (CRD)
-
Kubernetes custom resource that declares a named group of entry-point agents that collaborate to handle a workflow. The operator crawls each entry point’s sub-agent graph and records the transitive agents and tools in
status. - AI Gateway / Model Router
-
Model facade and provider abstraction in front of Large Language Model providers. Routes LLM requests, manages credentials, and exposes telemetry. Defined by the
AiGatewayandAiGatewayClassCRDs. - AI Guardrails
-
Content inspection and policy enforcement for traffic flowing through gateways. Defined by the
GuardandGuardrailProviderCRDs. Two implementation modes are supported: an adapter mode that delegates enforcement to an external service, and a native mode where the gateway implementation enforces the policy directly. - AiGateway / AiGatewayClass (CRDs)
-
The AI gateway resource (an instance) and its pluggable class (selects an implementation). Note the lowercase
i— the Go type isAiGateway. - Audit Trail (planned)
-
Logging and tracking of AI operations, decisions, and interactions for regulatory compliance, security monitoring, and operational transparency.
B
- BYOC (Bring Your Own Cloud)
-
Deployment model that lets organizations run the Agentic Layer within their own cloud infrastructure, retaining control over data, security, and compliance.
C
- Cloud-Native Architecture
-
Design approach based on containerization, microservices, dynamic orchestration, and declarative APIs. Built for cloud environments with Kubernetes as the foundation.
- Compliance Dashboard (planned)
-
Management interface for real-time monitoring and reporting against regulatory requirements such as the EU AI Act and GDPR.
- Connectors & Tools
-
Integration components that connect the Agentic Layer to external systems, databases, APIs, and third-party services.
- Control Plane for Intelligent Workloads
-
The Agentic Layer’s primary function as a management and orchestration system for AI-driven processes and autonomous agents within enterprise environments.
- CRD-class pattern
-
The
*Classpluggability mechanism shared byAgentGatewayClass,AiGatewayClass,ToolGatewayClass, andGuardrailProvider. The class CRD names an implementation; the instance CRD references a class. This lets the contract live in the Agent Runtime Operator while implementations live in separate operator repositories.
D
- Data Sovereignty
-
Maintaining control and governance over data location, processing, and access within defined jurisdictional and organizational boundaries.
G
- Guard (CRD)
-
Kubernetes custom resource that binds a guardrail policy to a target — a gateway, an agent, or a tool server.
- GuardrailProvider (CRD)
-
Kubernetes custom resource that names the implementation enforcing a `Guard’s policy.
K
- Kubernetes Platform
-
Infrastructure layer providing container orchestration, scaling, resource management, and service discovery for all Agentic Layer components.
- Kubernetes-Native
-
Architecture and components designed to use Kubernetes primitives, APIs, and operational patterns for deployment, scaling, and management.
L
- LLM (Large Language Model)
-
AI models trained on text to understand and generate human-like text. Examples include GPT, Gemini, and Claude, accessed through the AI Gateway.
M
- MCP
-
Model Context Protocol. Used between the Tool Gateway and Tool Servers, both internal and external.
- Multi-Framework Runtime
-
Execution environment that supports agents built with different AI frameworks while providing consistent operational characteristics and management interfaces.
O
- Observability Dashboard
-
Operational interface for monitoring, metrics, distributed tracing, and system health information across the Agentic Layer.
- OpenAI Chat Completion API
-
Protocol used by External Frontends to reach the Agent Gateway.
T
- Testbench
-
Agent validation and evaluation environment. Connects through the Agent Gateway like any other client.
- ToolGateway / ToolGatewayClass (CRDs)
-
The tool gateway resource (an instance) and its pluggable class (selects an implementation). Together they define a Tool Gateway deployment.
- ToolRoute (CRD)
-
Per-consumer routing for tool calls. Governs which tool servers a given consumer can reach through a Tool Gateway.
- ToolServer (CRD)
-
Registers an MCP server — in-cluster or external — as a tool source.
