[EN]What is the Research Cloud?The Research Cloud is a cloud service that allows you to rent out physical machines and treat them just as if they were machines in your own research laboratory segment. Because the service works by loaning out actual physical machines, it enables users to avoid problems such as virtualization overhead as with virtual machines, or reduced performance due to the sharing of computational resources with other users. Because hardware is managed by the cloud’s administrators, there is no need to monitor or handle of disk breakdowns or memory faults. (In the event of a fault or breakdown, the administrators may halt operation of your machine or have you transfer to another machine as necessary.) As the Reserch Cloud, there are two cloud computing system based on Openstack.

現在、研究クラウドとして二つのシステムが稼働中です。
- AIC（＝Achademic AIC（＝Academic Inter Cloud, 第二世代研究クラウド）
- ABC（＝Achademic ABC（＝Academic Baremetal Cloud, 第三世代研究クラウド）
また、ABCではストレージサービス（AWSのEBSに相当する、10TBのブロックストレージ）を提供しています。
