For example, F1 instances have NVMe local instance storage. https://aws.amazon.com/ec2/instance-types/f1/

The NVMe interface to EBS volumes that is implemented in our Nitro system today is closest to a HBA with no additional caching. So, a storage tier.

There is a Nitro security chip that is integrated into the motherboard. SPI and I2C buses are routed through the security chip. During system reset, the security chip holds motherboard components in reset while firmware is inspected out of

NVMe is just how the storage is surfaced -- the hardware programming interface for the block device. Hardware iSCSI initiators (HBAs) also have a hardware programming interface, but at the end of the day you talk SCSI over that interface. N

The local NVMe storage for i3.metal is the same as i3.16xlarge. There are 8 NVMe PCI devices. For i3.16xlarge those PCI devices are assigned to the instance running under the Xen hypervisor. When running i3.metal, there simply isn't a

Our goal is to for the majority of virtualized EC2 instances to be indistinguishable from bare metal (if not better). In most CPU and memory intensive benchmarks there is very little difference between an virtualized EC2 instance and bare m

EC2 Bare Metal instances boot from an EBS volume that is accessed via a NVMe PCI device (implemented in ASICs built by Annapurna Labs), just like virtualized C5 instances.

The NIC that is used by EC2 Bare Metal instances is an Elastic Network Adapter (ENA) PCI device that surfaces a logical VPC Elastic Network Interface. ENA is implemented in an ASIC that we design and build. When ENA is used in virtualized i

You cannot update firmware / tinker with BIOS etc. I will cover this in a breakout session at re:Invent today: https://www.portal.reinvent.awsevents.com/connect/search.ww#...

EC2 Bare Metal instances provide all the typical Intel processor features, including VT-x and VT-d. Yes you can use KVM.

Pricing will come with general availability. I suspect (and hope) everyone will be surprised and happy with the price.

These are billed the same as any other EC2 instance: per second.

15 Elastic Network Interfaces (ENIs) can be attached, just like i3.16xlarge.

This is a topic that we're continuing to iterate on between EBS, CloudWatch, and the AWS console team for metrics. When a newly introduced behavior makes step function changes in graphs displayed in the AWS console it doesn't meet

And I could speculate on hypervisor bypass in Andromeda 2.1 ;-)

Does the updated documentation at http://docs.aws.amazon.com/AmazonCloudWatch/latest/monitorin... explain the CloudWatch metrics?

It's difficult to make an simple comparison because neither hypervisor is used "out of the box" by EC2. For example, a lot of hypervisor benchmark comparisons focus on I/O performance, but the latest generation EC2 insta

"CPU" is commonly used in operating systems to describe any logical processor, no matter if it is a thread from a core for processors that implement simultaneous multithreading (like Intel Hyper-Threading Technology). vCPU is the
