As the adoption of confidential computing continues to grow, customers expect their confidential workloads to be strongly separated from their underlying cloud providers. To better align with these user requirements, Canonical is excited to announce ephemeral OS disks for Ubuntu confidential VMs (CVMs) on Microsoft Azure – a new solution that enables you to store disks on your VM’s OS cache disk or temp/resource disk, without needing to save them to any other remote Azure Storage.
Empowering customers with a Virtual Trusted Platform Module (vTPM) that doesn’t preserve its state across reboots, this solution lays the foundation for a more meaningful remote attestation solution and reduces dependence on cloud infrastructure.
Before we dig deeper into ephemeral OS disks and vTPMs, let’s take a look at the current state of confidential computing and its limitations.
