High-Level Build Configuration

Introduction

This guide won't cover topics such as high availability, failover and resilience. If or how you build resilience into your design is a complex topic and there are many different ways it could be achieved. There is also a risk that including processes like automatic failover could cause double-signing of proposals which could at a future date lead to slashing.

We will be configuring two servers. In both cases there is an assumption you have already built the servers and are starting at a base Linux image level. There are plenty of guides and tutorials on the Internet on how to build and correctly configure an EC2 Instance which I won't provide here.

1. The Radix Validator Node Server

2. A Web Server for hosting Prometheus and Grafana
