--- title: 'Try Ubuntu confidential VMs with Intel TDX today: limited preview now available on Azure' description: This article discusses the limited preview of Ubuntu Confidential VMs with Intel TDX on Microsoft Azure, which is a significant step towards building a strong foundation for a zero-trust security strategy in the cloud. It explores the concept of confidential computing and how it represents a fundamental shift to the threat model of the public cloud. The article also highlights the features of Intel TDX and how it allows users to run their workload within a logically isolated hardware-rooted execution environment. Additionally, the article provides helpful links to join the Intel TDX limited preview, watch a webinar to learn more about confidential computing, and read related blog posts. url: https://canonical.com/blog/ubuntu-confidential-vms-intel-tdx-microsoft-azure-confidential-computing?format=md --- 1.

As part of the [DCev5-series and ECesv5-series VMs](https://azure.microsoft.com/en-us/updates/confidential-vms-with-intel-tdx-dcesv5-ecesv5/), they’re available for you to try today! This exciting development is an important milestone in Ubuntu’s journey to power the confidential public cloud of the future. # Confidential computing threat model With cloud technology enabling faster and more flexible infrastructure deployment than ever before, security challenges have also become more complex. Traditionally, any vulnerability within the millions of lines of code in the cloud’s privileged system software (such as the operating system, hypervisor, and firmware) would compromise the confidentiality and integrity of the running code and data. Similarly, a malicious cloud administrator could potentially access the VM or its platform, compromising the security of your data. ## Intel Trust domain extensions – TDX Confidential computing represents a fundamental shift to the threat model of the public clouds .As such, Intel TDX, which comes with the new 4th Generation Intel Xeon CPUs, allows you to run your workload within a logically isolated hardware-rooted execution environment. This is achieved by TDX carving out a portion of system memory which is encrypted at run-time by a new AES-128 encryption engine, and by adding new access control checks that mediate access to this memory, and prevent external access to it even from the cloud’s privileged system software. To verify the security claims of confidential VMs, native support for attestation with [Microsoft Azure Attestation](https://azure.microsoft.com/en-us/products/azure-attestation/) will also  be available in the future. This will provide a hardware-rooted cryptographic proof, including a measurement/hash that attests to the integrity of the software loaded into the TEE, and a cryptographic signature that attests to the authenticity of the cloud’s TEE hardware. # Try Ubuntu confidential VMs today Intel TDX Ubuntu Confidential VMs on Azure is a key step towards building a strong foundation for a [zero-trust security strategy](https://canonical.com/blog/build-foundation-zero-trust-strategy-ubuntu-confidential-computing) in the cloud.
