ADK Production

Complete guide for deploying, securing, testing, and monitoring ADK agents in production. Covers deployment platforms, security guardrails, authentication, testing frameworks, tracing, and observability.

When to Use

Deployment:

• Deploying agents to production
• Choosing between hosting options (Agent Engine, Cloud Run, GKE)
• Configuring auto-scaling
• Setting up CI/CD for agents
• Integrating with Vertex AI services

Security:

• Validating or filtering user input
• Filtering agent responses before delivery
• Implementing OAuth or API key authentication
• Creating reusable security plugins
• Blocking unsafe topics or content

Quality & Testing:

• Creating test suites for agents
• Evaluating agent responses against criteria
• Debugging execution with tracing
• Setting up production monitoring
• Automated testing with synthetic users

When NOT to Use

• Local development → Use @adk-getting-started instead
• Agent creation → Use @adk-agents instead
• Tool integration → Use @adk-tools instead
• General callbacks → Use @adk-behavior instead
• Multi-agent systems → Use @adk-multi-agent instead

Key Concepts

Deployment

Agent Engine is the recommended managed deployment. Auto-scales, integrates with Vertex AI services, no infrastructure management.

Cloud Run offers container control with serverless scaling. Build custom Docker images for more control over the runtime.

GKE (Kubernetes) provides enterprise-scale deployment. Full control over infrastructure, networking, and scaling policies.

Deployment CLI: adk deploy handles Agent Engine deployment. For Cloud Run/GKE, containerize with adk api_server.

Environment Configuration: Use environment variables for credentials. Never commit secrets to source control.

Security

Input Guardrails validate user input before processing. Use before_model_callback to block or modify unsafe requests.

Output Guardrails filter agent responses before returning to users. Use after_model_callback to redact PII, profanity, or sensitive data.

Authentication secures tool access. Configure OAuth credentials for Google APIs or custom authentication for third-party services.

Security Plugins bundle reusable security callbacks. Create plugins for logging, rate limiting, or content moderation.

Credential Management uses environment variables and secure storage. Never hardcode secrets in agent code.

Quality & Testing

Evaluations (Evals) test agent behavior against expected outputs. Define test cases with inputs and expected results, measure pass rates.

Tracing captures execution flow for debugging. Cloud Trace integration shows LLM calls, tool executions, and timing.

Logging provides structured event capture. Use LoggingPlugin for consistent log formatting and levels.

Observability integrates with third-party platforms (AgentOps, LangSmith) for production monitoring and analytics.

User Simulation automates testing with synthetic conversations. Generate diverse test scenarios without manual testing.
