HashiCorp - Vault Associate Study Guide

8: Vault deployment architecture

This chapter turns the single-cluster mechanics defined earlier into a full production deployment surface, defining the node counts, storage backends, unseal strategies, and cross-cluster replication that carry a Vault installation into a multi-region operation. It walks through the cluster strategy for both self-managed nodes and the HashiCorp-managed HCP Vault service, and separates the two replication flavours so that a candidate can match a business requirement to the correct topology.
