# Consensus Model

This section covers how to configure your microservice's consensus model and high availability policy.

## Overview

Talon supports two consensus models for maintaining consistency across replicated microservices:

* **Event Sourcing** - POJO-based stores with event replay for consensus
* **State Replication** - ADM-generated state objects with automated replication

The HA policy determines how your microservice behaves in a cluster and which consensus model it uses.
