Commodity servers are well used for those services, and service providers face a problem to lower the cost of running numbers of servers. Consolidating multiple servers by using virtual machines is an effective approach to reduce unnecessary costs such as floor space, power, and management, which results in better resource utilization. On the other hand, consolidating multiple servers to a single server may increase the risk of single point of failure. Although high availability architectures should be considered for this, current solutions require specially designed hardware, or modifications to running software. In this paper we propose Kemari, a cluster system that synchronizes virtual machines for fault tolerance that does not require specific hardware or modifications to software. We present the design, implementation and evaluation of our system.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"24","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌コンピューティングシステム（ACS）"}],"bibliographicPageStart":"13","bibliographicIssueDates":{"bibliographicIssueDate":"2010-03-16","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"1","bibliographicVolumeNumber":"3"}]},"relation_version_is_last":true,"weko_creator_id":"10"}}
