Amazon Web ServicesEC2 在世界末日時發表 120GB RAM、16 virtual core、48TB disk (24 disks) 的「EC2 虛擬機」:「The New EC2 High Storage Instance Family」。

看起來像是 12 顆 7.2KRPM 的 2TB SATA,每顆如果可以跑到 200MB 就是 2.4GBytes/sec?如果是這種規格,給大量 sequence read/write 的運算超適合,官方 blog 的說明裡的解釋也是接近這個方向:

This instance family is designed for data-intensive applications that require high storage density and high sequential I/O -- data warehousing, log processing, and seismic analysis (to name a few). We know that these applications can generate or consume tremendous amounts of data and that you want to be able to run them on EC2.

目前只在 US-East (Northern Virginia) 有,USD$4.60/hour,硬算 720 小時,大約是每個月台幣十萬...

AWS 最近在補的硬體可以看出來是 Hybrid Hosting 的路線:這些機器應該是一台只跑一個 instance,跟 Dedicated Hosting 差不多。上面跑虛擬化只是為了算錢 (accounting) 以及一些安全機制 (像是防止 IP spoof,以及配合 EC2 提供的 firewall)。

實質上不太能說 AWS 不是 Hybrid Hosting 了...
