AWS 推出新的 Bare Metal Instances

AWS 針對各個 family type 都推出 Bare Metal 版本:「Now Available – Five New Amazon EC2 Bare Metal Instances: M5, M5d, R5, R5d, and z1d」。

AWS 第一次推出 Bare Metal 版本是在 2017 年年末推出的 i3.metal:「Amazon EC2 推出第一款 Bare Metal 的 Instance」,這樣算一算也一年多了,這次算是補產品線...

要注意的是,這次推出依照區域有不同的機種,像是 Ohio 沒有 z1d.metal 但有其他四種,N. California 則是沒有 m5d.metal 但有其他四種... 要先看一下表格才能確認每一區的情況 @_@

Vultr 也推出 Bare Metal 的機器了

AWS 推出 Bare Metal 版本的 Instance 後 (參考「Amazon EC2 推出第一款 Bare Metal 的 Instance」),Vultr 也推出 Bare Metal 機器了:「Deploy Bare Metal Cloud Servers With Vultr!」。

目前先在新加坡推出,之後會再往其他地區推出 :

We are first introducing bare metal in Singapore and more locations will be rolled out in the coming weeks.

在「Vultr Bare Metal - Dedicated servers with hourly billing. - Vultr.com」頁可以看到目前只提供一種機器,E3-1270v6 + 32GB RAM + 2*240GB SSD,一個月 USD$300 ($0.446/hr)。

對照 AWS 提供的 E5-2686v4 + 512GB RAM + 15.2TB SSD,Vultr 的這個規格很微妙... 會有 bare metal 需求通常是因為效能上的不足,但你給的這個規格感覺就鳥鳥的,對效能的幫助好像不大啊...

Amazon EC2 推出第一款 Bare Metal 的 Instance

Amazon EC2 直接租整台主機出來了:「Amazon EC2 Bare Metal Instances with Direct Access to Hardware」。

Bare Metal 怎麼翻譯比較好啊?雖然知道是拔掉虛擬化的主機... 裸奔機?

We knew that other customers also had interesting use cases for bare metal hardware and didn’t want to take the performance hit of nested virtualization. They wanted access to the physical resources for applications that take advantage of low-level hardware features such as performance counters and Intel® VT that are not always available or fully supported in virtualized environments, and also for applications intended to run directly on the hardware or licensed and supported for use in non-virtualized environments.

反正這種機器就是要壓榨整台機器的效能,所以不會拿小台機器出來給大家玩。這次推出的是 i3 系列,叫做 i3.metal

Today we are launching a public preview the i3.metal instance, the first in a series of EC2 instances that offer the best of both worlds, allowing the operating system to run directly on the underlying hardware while still providing access to all of the benefits of the cloud. The instance gives you direct access to the processor and other hardware, and has the following specifications:

Processing – Two Intel Xeon E5-2686 v4 processors running at 2.3 GHz, with a total of 36 hyperthreaded cores (72 logical processors).
Memory – 512 GiB.
Storage – 15.2 terabytes of local, SSD-based NVMe storage.
Network – 25 Gbps of ENA-based enhanced networking.

走了十年總算走到這塊了... 不過應該花了不少時間解決各種安全性的問題,像是 network isolation 以及反刷韌體的問題 XD
