This repository contains guides with not only a simple installation option, but also advanced security settings that are highly recommended for mainnet validators.
By these documentations we will setup server security. After that, for Cosmos SDK apps we will run node with Sentry Node Architecture for DDoS mitigation. And will make a validator protection from double signing incident by tmkms. In addition, it is recommended to use Monitoring to monitor all your servers as validator, sentry nodes, tmkms server etc. Also, for more conviniate way of bynary upgrading - you can use Cosmovisor.
Another important topic for Cosmos Hub networks is ibc relayer - we will walk through the installation of Hermes IBC relayer.
Below is a schematic example of what your customized architecture of Cosmos SDK apps might look like.
