Flexibility and security. Two characteristics that cannot be compromised in the age of multi-cloud and DevOps, yet most secrets management tools were designed around the idea that both cannot be achieved together. Enter HashiCorp Vault, built around the philosophy that securing secrets is more effective when the interaction of a secrets management service aligns with other DevOps tools available today. Vault has quickly become the de-facto solution in secrets management over recent years, finding its way into many Global 2000 companies. This book will cover multiple aspects of Vault, from planning the service, architectural design, and deployment of Vault, to managing the service once it is up and running. With a combined 40 years of experience working in technology and more than three years working specifically with Vault, Bryan and Dan walk users through the process of designing and building a production-ready Vault service.
