VMware vSphere 7 Now Supports AMD SEV-ES Encryption!

VMware vSphere 7 Now Supports AMD SEV-ES Encryption!

VMware just announced that vSphere 7 Update 1 will add support for AMD SEV-ES encryption!

Find out what this means for enterprise security, and the future of AMD EPYC processors!

 

AMD SEV-ES Encryption : What Is It?

SEV-ES, short for Secure Encrypted Virtualization-Encrypted State, is a hardware-accelerated encryption capability in AMD EPYC processors.

Leveraging both the AMD Secure Processor and the AES-128 encryption engine built into every AMD EPYC processor, SEV-ES encrypts all CPU register contents when a virtual machine stops running.

This prevents the leakage of information from the CPU registers to components like the hypervisor. It can even detect malicious modifications to a CPU register state.

 

VMware vSphere 7 Now Supports AMD SEV-ES Encryption!

VMware vSphere 7 Update 1 adds support for both AMD SEV-ES and AMD EPYC processors.

The AMD Secure Processor in the first-generation EPYC processors can handle up to 15 encryption keys.

That increases to more than 500 encryption keys with the second-generation EPYC processors.

ESXi has many layers of isolation within its virtualised infrastructure, but all of that is implemented in software. They still require a level of trust in the hardware, which is where AMD SEV-ES comes in.

A guest operating system that supports SEV can ask the AMD Secure Processor to issue it an encryption key, for full in-memory, in-hardware encryption.

SEV-ES extends that protection to CPU registers, so that the data inside the CPU itself is encrypted. This protects the data from being read or modified when the virtual machine stops running.

Even a compromised hypervisor that accesses the register data cannot make use of it, because it is now encrypted.

Needless to say, adding support for AMD SEV-ES in vSphere 7 will spur the uptake of AMD EPYC processors in the datacenter.

Google Cloud Confidential VM With 2nd Gen AMD EPYC!

Google recently introduced Confidential Computing, with Confidential VM as the first product, and it’s powered by 2nd Gen AMD EPYC!

Here’s an overview of Confidential Computing and Confidential VM, and how they leverage the 2nd Gen AMD EPYC processor!

 

Google Cloud Confidential Computing : What Is It?

Google Cloud encrypts customer data while it’s “at-rest” and “in-transit“. But that data must be decrypted because it can be processed.

Confidential Computing addresses that problem by encrypting data in-use – while it’s being processed. This ensures that data is kept encrypted while in memory and outside the CPU.

 

Google Cloud Confidential VM, Powered By 2nd Gen AMD EPYC

The first product that Google is unveiling under its Confidential Computing portfolio is Confidential VM, now in beta.

Confidential VM basically adds memory encryption to the existing suite of isolation and sandboxing techniques Google Cloud uses to keep their virtual machines secure and isolated.

This will help customers, especially those in regulated industries, to better protect sensitive data by further isolating their workloads in the cloud.

Google Cloud Confidential VM : Key Features

Powered By 2nd Gen AMD EPYC

Google Cloud Confidential VM runs on N2D series virtual machines powered by the 2nd Gen AMD EPYC processors.

It leverages the Secure Encrypted Virtualisation (SEV) feature in 2nd Gen AMD EPYC processors to keep VM memory encrypted with a dedicated per-VM instance key.

These keys are generated and managed by the AMD Secure Processor inside the EPYC processor, during VM creation and reside only inside the VM – making them inaccessible to Google, or any other virtual machines running on the host.

Your data will stay encrypted while it’s being used, indexed, queried, or trained on. Encryption keys are generated in hardware, per virtual machine and are not exportable.

Confidential VM Performance

Google Cloud worked together with the AMD Cloud Solution team to minimise the performance impact of memory encryption on workloads.

They added support for new OSS drivers (name and gvnic) to handle storage traffic and network traffic with higher throughput than older protocols, thus ensuring that Confidential VM will perform almost as fast as non-confidential VM.

Easy Transition

According to Google, transitioning to Confidential VM is easy – all Google Cloud Platform (GCP) workloads can readily run as a Confidential VM whenever you want to.

Available OS Images

In addition to the hardware-based inline memory encryption, Google built Confidential VM on top of Shielded VM, to harden your OS image and verify the integrity of your firmware, kernel binaries and drivers.

Google currently offers images of Ubuntu v18.094, Ubuntu 20.04, Container Optimized OS (COS v81), and RHEL 8.2.

They are currently working with CentOS, Debian and other distributors to offer additional OS images for Confidential VM.

2nd Gen EPYC – Everything You Need To Know Summarised!

Leveraging their new Zen 2 microarchitecture and 7 nm process technology, AMD just introduced their 2nd Gen EPYC processors.

Designed to challenge Intel Xeon in the enterprise, cloud and HPC markets, the 2nd Gen EPYC processors promise to deliver “record-setting performance“, while reducing TCO (Total Cost of Ownership) by up to 50%.

Here is everything you need to know about the new 2nd Gen EPYC processors… summarised!

 

The Official 2nd Gen EPYC Product Presentation Summary

Let’s start with a quick 7.5 minute summary of the 2nd Gen EPYC product presentations by Dr. Lisa Su, Mark Papermaster and Forrest Norrod!

Now, let’s take a look at its key features and specifications!

AMD Infinity Architecture Explained

The AMD Infinity Architecture is a fancy name for their new modular chiplet-based design. It allows them to combine up to eight processor dies with a single I/O die on the same package, faster and at lower cost.

The processor dies are fabricated with the industry-leading 7 nm process technology for best performance at lowest power consumption, and thermal output.

The I/O die, on the other hand, can be fabricated on the much cheaper 14 nm process technology, with a much higher yield.

2nd Gen EPYC Is Built On 7nm

The 2nd Gen EPYC processor cores are fabricated on the 7nm process technology. This allows AMD to fit more transistors into a smaller space.

By doubling the transistor density, coupled with microarchitectural optimisations, the 2nd Gen EPYC delivers 4X the floating point performance of the 1st Gen EPYC processors.

The smaller process also increases energy efficiency, reducing both power consumption and heat output. According to AMD, 2nd Gen EPYC will use half the power consumption as the 1st Gen EPYC at the same performance level.

Industry-Leading Performance

AMD claims they will offer up to 90% better integer performance and up to 79% better floating-point performance, than the competing Intel Xeon Platinum 8280 processor.

On top of significantly better performance per socket, they also come with hardware memory encryption, and a dedicated security processor.

Baked-In Security On Multiple Levels

The 2nd Gen EPYC processors are built-in with multiple levels of security features, to harden it against cyberattacks.

  • They have a secure root of trust designed to validate the initial BIOS boot without corruption.
    In virtualised environments, you can use it to cryptographically check that your entire software stack is booted without corruption.
  • They have memory encryption engines built into their memory channels to hardware-encrypt data in the memory, preventing cold boot attacks.
  • In the 2nd Gen EPYC, every virtual machine is now encrypted with one of up to 509 unique encryption keys known only to the processor.
    This protects your data even if a malicious VM finds its way into your virtual machine memory, or if a compromised hypervisor gains access into a guest VM.

2nd Gen EPYC Is PCI Express Gen 4 Ready!

Like the 3rd Gen Ryzen processors, the 2nd Gen EPYC is PCI Express Gen 4 ready.

PCIe 4.0 doubles the bandwidth over PCIe 3.0, and every EPYC processor has 128 lanes to tie together HPC clusters, or connect to GPU accelerators and NVMe drives.
