The AWS quick start guides for HashiCorp Vault have been updated to be compatible with Vault 1.6, addressing key features such as integrated storage using the Raft Consensus Algorithm, auto-unseal capabilities via AWS KMS, and support for AWS ACM Private CA for Load Balancer. Additionally, a Helm chart is supported on Amazon EKS Control Plane for deploying Vault, making it easier for users to get started with Vault or integrate it into their existing environment.
