Configure a Highly Available Cluster

What Should a Cluster Look Like?

• Ideally, we want something that provides redundancy, failure tolerance, scalability, and a fully replicated architecture
• For Vault Enterprise, you are limited to either Integrated Storage or Consul storage backends
• HashiCorp (and consultants like me) are moving away from Consul as the primary storage backend and using Integrated Storage for everything
• The Vault Operations Professional exam will NOT feature Consul as a configuration or deployment option
