Amazon EC2 Metal instances provide you with physical CPUs, not virtualized CPUs. Metal instances are not virtualized; they do not run under a hypervisor like non-Metal instances do. We do use the same "vCPU" terminology in our APIs and the EC2 Console even with Metal instances, but rest assured you will have full access to all CPU resources.
Just a point of clarity - EC2 Dedicated Hosts are different from Metal instances. EC2 Dedicated Hosts are intended to run multiple EC2 instances on the same physical machine; you allocate a Dedicated Host and then can assign EC2 instances to that host. Dedicated Hosts are not EC2 instances themselves; you cannot run workloads on them or access them until you assign instances to them. Metal instances, on the other hand, are EC2 instances mapped to entire physical hosts that cannot be subdivided into multiple EC2 instances. (You can even run your own hypervisor on Metal instances if you like, which is something you cannot do with non-Metal instances.) Answer from MichaelFischer on repost.aws

Hello,
I think that you want to read https://docs.aws.amazon.com/whitepapers/latest/security-design-of-aws-nitro-system/the-components-of-the-nitro-system.html especially the "Nitro hypervisor" section to understand why AWS still speaks of vCPU with bare metal instances.
If you are not familiar with Nitro, you may want to start here: https://aws.amazon.com/ec2/nitro/
Best,

r/aws on Reddit: AWS bare metal service - questions
December 28, 2022 -
Hi everyone! I've been trying to understand certain AWS features & pricing and would really appreciate insights based on your ezlerience.
What discounts normally apply for 1 and 3 year reservations respectively of EC2 or RDS storage capacity, if any? This concerns storage products such as gp2, gp3, io1, io2, st1, database magnetic and backup storage
What is the listing/discounted price for 1 and 3 years reservations of bare metal instances of types ls4gen and D3gen? In which availability zones are these services available?
There is a thin hypervisor layer on top of bare metal deployed by AWS. Generally speaking, do user space applications run on top of aws bare metal instances (specifically interested in intel spdk)?
Appreciate input on any of these!

1+2: You can look up your pricing questions 1&2 in the AWS pricing calculator. You can create an estimate and play around with the discounts of reservations. https://calculator.aws/#/ 3: Most workloads do not run on AWS Bare metal. It is an uncommon practice. It is reserved for specialized workloads that require direct access to hardware or legacy workloads. There is a huge shift towards abstraction away from bare metal starting with EC2, ECS Fargate running Containers, all the way up to software functions with Lambda. If you use a traditional approach to AWS and are looking to rent bare metal servers with reservations for up to 3 years, then you will find AWS to be a highly expensive option. AWS provides Cloud Computing. It provides on-demand capacity that you scale up and down seamlessly. Functionality is continually offered at a higher abstraction level that allows you to focus on business value instead of maintaining infrastructure. While infrastructure costs look higher at face value, the end result is lower total cost of value and faster time to market. I hope this insight helps you understand AWS. Because we might all look like idiots being hyped up over AWS without it seeing how largely expensive it can be.
