Amazon EC2 的 Dedicated Hosts 正式推出

Amazon EC2 在十月預告了 Dedicated Hosts (參考「Amazon EC2 預定要推出的 Dedicated Hosts」),在今天正式推出來讓大家用:「Now Available – EC2 Dedicated Hosts」。

價錢在「Amazon EC2 Dedicated Host Pricing」這邊,租用就是整台一起租用,所以價錢都是以 Instance Family 在計算,在一台 Dedicated Host 上面可以跑的虛擬機數量與 Instance Type 有關,舉例來說:c4 只能跑一個 8xlarge,也可以跑兩個 4xlarge。

一台 Dedicated Host 當然可以跑很多 Instance,不過只能跑一樣的大小的 Instance Type:

I choose the instance type (Dedicated hosts for M3, M4, C3, C4, G2, R3, D2, and I2 instances are available), the Availability Zone, and the quantity (each Dedicated Host can accommodate one or more instances of a particular type, all of which must be the same size).

另外 Dedicated Hosts 一定要放到 VPC 內 (理論上新帳號都有強迫這樣了),不過可以跨 VPC 就是了:

Instances launched on a Dedicated Host must always reside within a VPC. A single Dedicated Host can accommodate instances that run in more than one VPC.

目前能開的數量有限制,有需要更多的人可以開 support ticket 去要:

You can allocate up to 2 Dedicated Hosts per instance family (M4, C4, and so forth) per region; if you need more, just ask.
