This white paper is meant to be a reference deployment guide for customers who would like to use HAProxy with their ECS deployment. Its intent is to provide a reference or an example for customers to deploy ECS with HAProxy. Load balancing is optional and not part of ECS except for CAS. A quick overview of ECS object access will be covered in this white paper. For a more in-depth overview of ECS Architecture and description of how ECS handles and processes object and file access, refer to ECS Architecture and Overview white paper.
