Can HashiCorp Vault be deployed in high availability mode?

HashiCorp Vault supports high availability configurations to ensure that the system remains operational and resilient in the face of failures. When deployed in high availability mode, multiple Vault server instances can be configured to work together, providing fault tolerance and load balancing. This configuration leverages a leader-follower setup, where one instance acts as the leader responsible for handling write operations, while others serve as standby servers that can take over if the leader fails.

This capability is essential for production environments where uptime and reliability are critical. High availability also allows for better resource utilization and scalability, accommodating increased demand without compromising performance. Therefore, being able to configure Vault for high availability is a pivotal feature that empowers organizations to maintain secure access to sensitive information even in adverse conditions.
