## Description

Remote Procedure Call (RPC) frameworks provide a convenient abstraction for request-response communication. In practice, their implicit time constraints and sensitivity to intermittent failures present challenges. As a result, developers often abandon RPC and accept the complexity of asynchronous APIs, queues, and orchestration layers.

This session introduces Nexus RPC, a new open standard that brings the simplicity of RPC to long-running, fault-tolerant operations. Unlike traditional RPC, operations persist independently of client or service lifecycles and can be tracked, resumed, or cancelled at any point—even after outages or restarts. It's RPC reimagined for the realities of modern applications.

Attend this session to learn what Nexus RPC is and how it addresses fundamental challenges in distributed systems. You'll also discover why it is particularly valuable for agentic AI, as it enables LLM-powered agents to reliably invoke external tools and monitor long-running operations.
