Overview
Course Description
Build multi-agent AI systems with Agent2Agent protocol across platforms and vendors. A2A foundations cover features, benefits, motivating use cases, the relationship to MCP, and the key concepts that ground the protocol. Agent Cards, skills, and discovery cover Agent Card structure and metadata, capability declarations, skills definition, well-known endpoints for publishing, dynamic-discovery patterns, and embedded authentication requirements. The A2A task lifecycle covers task states and properties, levels of agents and task complexity, parallel and sequential tasks, Context IDs, the request/response pattern with polling, and streaming with Server-Sent Events. Enterprise security, multi-agent coordination, and extensions cover HTTPS and TLS transport security, authorization, opaque execution, the OWASP Top 10 for LLMs as a security taxonomy, agent collaboration patterns, task delegation and sub-agent coordination, workflow state management, human-in-the-loop integration, observability, A2A protocol extensions, implementation best practices, and the future of agent-to-agent communication. Hands-on labs produce an A2A development environment, published Agent Cards, an OAuth-secured endpoint, multi-agent workflows, and a custom protocol extension. The course is designed for senior software developers, AI/ML engineers, and enterprise architects.

The Agent2Agent Task Lifecycle
By the end of this module, you will be able to model A2A task states and properties, structure parallel and sequential tasks, use Context IDs, apply request/response with polling, and stream with Server-Sent Events.
- Task States and Properties
- Levels of Agents and Task Complexity
- Parallel and Sequential Tasks
- Using the Context ID
- Request/Response Pattern with Polling

Enterprise Security and Authentication
By the end of this module, you will be able to apply transport security with HTTPS and TLS, implement authorization and access control, apply opaque execution, and mitigate risks aligned with the OWASP Top 10 for LLMs.
- Transport Security with HTTPS and TLS
- Authorization Patterns and Access Control
- Opaque Execution
- OWASP Top 10 for LLMs
- Security Patterns for A2A
- Hands-on Lab: Enable OAuth 2.0 authentication on an A2A endpoint and identify and mitigate the OWASP Top 10 risks specific to it.
Multi-Agent Coordination
By the end of this module, you will be able to design agent collaboration patterns, delegate tasks across sub-agents, manage workflow state, integrate human-in-the-loop, and instrument monitoring and observability for the resulting system.
- Designing Agent Collaboration Patterns
- Task Delegation and Sub-agent Coordination
- Workflow State Management
- Human-in-the-Loop Integration
- Monitoring and Observability
- Hands-on Lab: Create a complex multi-agent workflow with human-in-the-loop patterns and observability hooks.
Extensions, Best Practices, and Future Directions

- A2A Protocol Extensions
- Best Practices for A2A Implementation
- Future of Agent-to-Agent Communication
- Keeping Up with A2A Developments
- Hands-on Lab: Develop one A2A protocol extension and apply best practices to a sample A2A system.

Reviews
this class was informative, made me think about certifying for the suse manager cert.
Fantastic and great training. Tons of hands-on labs to really make you understand the material being thought.
They are very good and made sure we had all the appropriate materials for class.
You get detailed labs to guide you through the technical material giving you a hands on method of learning otherwise difficult material.
Some Labs are very good but some steps it ask to update but its already updated, but overall its very good training.
