Build and Deploy a Worker Node With AWS Node Runners

Welcome to the AWS Node Runners documentation! This page provides detailed instructions on how to leverage Node Runners on AWS, including benefits, setup instructions, and useful links.

Overview

Node Runners on AWS enables you to deploy and manage blockchain nodes efficiently using AWS infrastructure. Whether you're deploying Ethereum nodes or other blockchain networks, Node Runners simplifies the process, offering scalability, reliability, and cost-effectiveness.

For more detailed information and step-by-step guides, please refer to the AWS Node Runners Documentation (opens in a new tab).

Allora Network's AWS Infrastructure

This diagram illustrates the architecture of the integration between the Allora Network (built on a Cosmos AppChain) and an AWS-based infrastructure for handling inference requests.

Key Components

1. Allora Network (Cosmos AppChain)

   • Public Head Node: Acts as the entry point for the Allora Network, handling requests and responses.

2. AWS Account Setup

   • Region: The geographical location within AWS where the resources are deployed.
   • Virtual Private Cloud (VPC): Provides an isolated network environment within the AWS region.
     • Public Subnet: A subnet within the VPC that has access to the internet through the VPC Internet Gateway.
     • VPC Internet Gateway: Allows communication between the instances in the VPC and the internet.

3. EC2 Instance (Allora Worker Node)

   • Offchain Node: This component handles network communication, receiving requests from the Allora Network and sending responses back.
   • Node Function: Processes requests by interfacing with the private model server. It acts as an intermediary, ensuring the requests are correctly formatted and the responses are appropriately handled.
   • Model Server: Hosts the proprietary model. It executes the main inference script (Main.py) to generate inferences based on the received requests.

Process Flow

1. Request Flow:

   • The Allora Network's Public Head Node sends a request for inferences to the EC2 instance within the AWS environment.
   • The request passes through the VPC Internet Gateway and reaches the Offchain node in the public subnet.
   • The Offchain node forwards the request to the Node Function.
   • The Node Function calls Main.py on the Model Server to generate the required inferences.

2. Response Flow:

   • The Model Server processes the request and returns the inferences to the Node Function.
   • The Node Function sends the inferences back to the Offchain node.
   • The Offchain node communicates the inferences back to the Allora Network via the VPC Internet Gateway.
