RPC Reinvented: Asynchronous, Durable, and Agent-Ready

What if your remote calls could run for weeks and survive server crashes? This new standard combines durable execution with RPC to make your applications truly fault-tolerant.

Understanding the reliability challenges of traditional RPC

Traditional Remote Procedure Calls (RPC) are not inherently reliable for long-running operations because they don't handle process crashes or network failures.

The trade-offs of using event-driven systems for reliability

While event-driven systems offer reliability through queues, they sacrifice the simple API contract of RPC and lead to complex, callback-heavy code.

#3about 3 minutes

Building a fault-tolerant RPC with state persistence

A reliable RPC can be achieved by persisting request and response state in a database, allowing different process instances to handle recovery after a crash.

Combining durable execution with RPC for a better developer experience

Nexus RPC uses the concept of durable execution to preserve process state, enabling developers to write simple, synchronous-style code for long-running, fault-tolerant operations.

Applying Nexus RPC to build reliable AI agent tools

Nexus RPC is ideal for AI agents as it allows them to reliably invoke external tools that may be long-running, overcoming the limitations of traditional short-lived RPCs.

Demo of a fault-tolerant AI agent using Temporal

A live demonstration shows how an AI agent running in a Temporal workflow can invoke a long-running tool and survive process crashes without losing state.

Summary of Nexus RPC and durable execution benefits

Nexus RPC, enabled by durable execution platforms like Temporal, provides a reliable and simple RPC paradigm for long-running operations, avoiding the complexity of event-driven systems.
