 Azure offers a choice of Trusted Execution Environment (TEE) options from both AMD and Intel. These TEEs allow you to create Confidential VM environments with excellent price-to-performance ratios, all without requiring any code changes.
 
-For AMD-based Confidential VMs, the technology used is [AMD SEV-SNP](https://www.amd.com/system/files/TechDocs/SEV-SNP-strengthening-vm-isolation-with-integrity-protection-and-more.pdf), which was introduced with 3rd Gen AMD EPYC™ processors. On the other hand, Intel-based Confidential VMs utilize [Intel TDX](https://cdrdv2-public.intel.com/690419/TDX-Whitepaper-February2022.pdf), a technology introduced with 4th Gen Intel® Xeon® processors. Both technologies have different implementations, however both provide similar protections from the cloud infrastructure stack.

 ### Resizing
 
-Confidential VMs run on specialized hardware, so you can only [resize confidential VM instances](confidential-vm-faq.yml#can-i-convert-a-dcasv5-ecasv5-cvm-into-a-dcesv5-ecesv5-cvm-or-a-dcesv5-ecesv5-cvm-into-a-dcasv5-ecasv5-cvm-) to other confidential sizes in the same region. For example, if you have a DCasv5-series VM, you can resize to another DCasv5-series instance or a DCesv5-series instance.
