HashiCorp Certified: Vault Operations Professional 2022
Build Fault Tolerant Vault Environments
Section Overview Build Fault Tolerant Vault Environments
Welcome to this objective on building fault-tolerant HashiCorp Vault environments. In this lesson, we’ll cover enterprise-grade Vault deployments with a focus on clustering and multi-datacenter replication.
By the end of this section, you will be able to:
- Configure a Highly Available (HA) Vault cluster for resilience
- Enable and manage Disaster Recovery (DR) replication in Vault Enterprise
- Promote a DR secondary cluster to primary during an outage
We’ll start with setting up Vault HA clusters, then move on to configuring DR replication and failover procedures.
Note
High Availability (HA) in Vault ensures continuous access by running multiple active nodes behind a load balancer.
Disaster Recovery (DR) replication provides asynchronous standby clusters in separate datacenters.
Let’s begin with the HA cluster configuration.
