Unfortunately, the commercial public cloud service could not meet the expectation in case that collaboration with internal services may be required. Meanwhile, it could be hard for small colleges to carry initial and running cost of large-scale servers for on-premises private cloud infrastructure. This research objective realizes an in-campus open cloud service with utilizing surplus resource of classroom PCs. The classroom PCs used as a cloud platform have issues that they may be down unexpectedly, or occupied for lesson. This paper describes implementation of an open cloud infrastructure on such the unstable platform with proposed mechanism of dynamic reallocation of instances by using OpenStack's alive monitoring and CRIU's checkpoint & restore function.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告インターネットと運用技術（IOT）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2018-02-26","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"5","bibliographicVolumeNumber":"2018-IOT-40"}]},"relation_version_is_last":true,"weko_creator_id":"11"}}
