Agents Talking to Agents: MCP, A2A, and the Reality of Multi-Agent Orchestration in Production
Building a multi-agent system in a notebook is straightforward
Running one on production infrastructure, where a wrong handoff triggers a real incident, is a different problem entirely.
This talk shares hard-won lessons from deploying autonomous agents using both MCP and A2A protocols in a large-scale, regulated environment.
We move past the happy path and focus on what actually breaks: agents that lose task context mid-chain, trust boundaries that collapse during agent-to-agent delegation, tool conflicts between concurrent agents, and orchestration failures that only surface under real load.
We walk through three patterns that emerged from this work. How to split responsibilities between MCP and A2A so each protocol does what it is actually good at. How to scope agent authority using MCP server boundaries without creating coordination bottlenecks. And how to design agent-to-agent handoffs that degrade gracefully when part of the chain fails mid-task.
No toy examples. No vendor pitches. Concrete decisions, the tradeoffs behind them, and what we would change today. Attendees leave with patterns they can apply the next day, regardless of their agent framework.
How to actively protect users and assets of a 5G CloudNative network?
In today's hyperconnected world, where mobile networks are a key element of digital connectivity, the ability to quickly and accurately detect cyberattacks and fraudulent activity becomes paramount. Monitoring the security of 5G networks appears to be a central element in protecting users, but also IoT devices and telco-cloud infrastructures.
In this demo, we will see how cloud-native software solutions can enhance the reliability, performance and security of 5G telco-cloud networks.
Thus, we will explore the different means to effectively monitor traffic, identify potential security vulnerabilities and implement preventive detection measures. Furthermore, the 5G world opens up new perspectives, particularly via 5G Telco-APIs
Join us to share about mobile network security, to see how to not only react to, but also proactively anticipate and neutralize threats in the dynamic and ever-changing domain of 5G technology.
From Logs to Decisions: Autonomous AI Agents for Real-Time Kubernetes Threat Response
Cloud Native environments evolve faster than traditional security can handle. This session introduces an open-source, autonomous AI agent architecture leveraging Kubernetes, Kubeflow, and lightweight protocols like A2A and MCP to deliver real-time, adaptive threat detection and response.
Agents collect signals via OpenTelemetry, Falco, ELK and Prometheus, correlate behaviors using ML models trained in Kubeflow, and reason about threats like account takeover, lateral movement, or privilege escalation.
Integrated with policy engines like OPA, Kyverno and GitOps workflows, agents can trigger secure remediation actions such as rollback, isolation, or misconfiguration fix.
Each decision is transparently explained via contextual LLMs, ensuring auditability and trust.
Attendees will leave with practical templates, deployable AI pipelines, and actionable strategies to build explainable, autonomous, and scalable Kubernetes-native security defenses using CNCF and OSS technologies.
