To ensure great performance on Arm, Canonical also optimised Ubuntu 22.04 LTS images for AWS Graviton. “Canonical has been an important partner in this effort, working closely with us to bring confidential computing innovations to our customers”. Hardware-level encrypted guest isolation, combined with measured boot and TPM-backed full-disk encryption in Ubuntu and Azure Managed HSM, customer code and data are encrypted in use, in transit, and at rest using encryption keys that are protected and can be controlled by the customer,” said Vikas Bhatia, Head of Product for Azure Confidential Computing. “Azure’s confidential VMs deliver confidentiality between different cloud customers and also between customers and Azure operators. Ubuntu is the only Linux distribution supporting Azure Confidential VMs. A key new capability is Confidential Computing, which greatly improves data protection and privacy in leading public clouds without requiring any changes to existing application deployments.

Ubuntu is deeply integrated into public clouds and optimised for performance, security and ease of use. “Ubuntu 22.04 LTS unlocks innovation for industries with demanding infrastructure security requirements, such as telecommunications and industrial automation, underpinning their digital transformation.“ Confidential Computing and Arm drive public cloud innovation “Our mission is to be a secure, reliable and consistent open-source platform – everywhere”, said Mark Shuttleworth, CEO of Canonical. Canonical partners with industry leaders to deliver enterprise-grade security, long-term maintenance and support on all major architectures, hardware and clouds. Canonical Ubuntu 22.04 LTS is now generally available, featuring significant leaps forward in cloud confidential computing, real-time kernel for industrial applications, and enterprise Active Directory, PCI-DSS, HIPAA, FIPS and FedRAMP compliance – raising the bar for open source from cloud to edge, IoT and workstations.
