Why AI Agents Are Breaking Legacy Cloud Architecture

The rise of LLMs and AI agents is fundamentally challenging the 20-year-old architectural assumption that compute should be stateless and state should reside solely in databases. Current solutions like Durable execution and polling-based approaches fail to support long-running agents with persistent memory and real-time bi-directional interactions. This gap reveals an urgent need for new routing primitives to enable seamless communication between clients and stateful processes—a foundational shift that will reshape cloud service design.
