In the field of cloud infrastructure and security, it’s essential to automate and safeguard sensitive data. This talk explores a complex setup where Terraform is used to set up several virtual machines, showcasing advanced Infrastructure as Code methods. We concentrate on setting up a main Vault cluster using Ansible, an effective automation tool, to ensure smooth and repeatable deployments.
A key feature of this system is linking Vault's auto-unseal function with Azure Key Vault, presenting a strong method for secret handling and data security in cloud settings. This combination boosts security and streamlines operational processes.
Additionally, we examine the setup of another Vault cluster, which uses the Transit Secrets Engine. It relies on the central Vault cluster for its unsealing, highlighting Vault's flexibility and interconnection, and providing a layered security framework.
The session also covers the integration of OpenID Connect (OIDC) with Microsoft Entra ID (formerly known as Azure AD), vital for identity and access management, offering a secure and effective solution for authentication and authorization in cloud applications.
Altogether, our aim is to offer practical insights into using these technologies, giving participants a thorough grasp of utilizing Terraform, Ansible, Vault, Azure Key Vault, and Microsoft Entra ID for a secure and efficient cloud infrastructure.
