EC2 的 C5 系列機器推出 12x、24x 以及 metal 類別

EC2c5 系列主機推出了 12xlarge24xlarge 以及 metal 三種新的類別:「Now Available: New C5 instance sizes and bare metal instances」。

本來的 c5largexlarge2xlarge4xlarge9xlarge (這邊有一些不規則了),現在多了 12xlarge24xlarge,應該是大到需要依照硬體規格對齊數字了?

另外一個是,c5.24xlargec5.metal 其實是一樣的硬體規格 (以及價錢),主要的差異在 c5.metal 沒有虛擬化,所以除了壓榨效能以外,還可以看到很多硬體資訊:

  • do not want to take the performance hit of nested virtualization,
  • need access to physical resources and low-level hardware features, such as performance counters and Intel VT that are not always available or fully supported in virtualized environments,
  • are intended to run directly on the hardware, or licensed and supported for use in non-virtualized environments.
