Microservices architecture is entering a new phase. As AI agents move from experimentation into real software delivery, they are beginning to change not only how systems are built, but how backend services are designed, connected and consumed. This session explores the emergence of Agentic Microservices, a new evolution of microservices architecture shaped by the rise of autonomous and semi-autonomous AI systems. Rather than treating microservices purely as static APIs or isolated backend components, agentic architectures open up new patterns where services can become tools, agents can reason across workflows, and software systems can begin to orchestrate tasks more intelligently. The talk will introduce emerging concepts such as Microservices as Tools (MAT), where services are exposed and consumed in ways that make them directly usable by AI agents, and Agentic Monoliths, where agent-driven capabilities reshape how teams think about modularity, autonomy and system design. It will also explore why serverless is a natural fit for agentic architectures, supporting more flexible, event-driven and scalable approaches to building intelligent systems. Through a practical demonstration of an agentic microservice in action, attendees will see how these ideas move beyond theory and begin to influence real-world engineering patterns. For engineering leaders, architects, developers and product teams, this session offers a grounded look at how AI agents may reshape the next generation of backend architecture, and what organisations should start thinking about now as microservices continue to evolve.
