Abstract

クラウドコンピューティングの利用は着実に広がっている.特に一般利用者向けにサービスを提供するパブリッククラウドはすでに多様な分野で利用されており,クラウドの特徴を最大限に活用した事例も豊富である.一方で,企業向けのプライベートクラウドではクラウドのコストメリットを活かそうとする動きが主流である.本稿では,クラウドの特徴の1つであるオンデマンド・セルフサービスを活かしたプライベートクラウドの企業内での利用モデルを提案し検証する.検証手段として,実際の業務に利用できるIaaS型のプライベートクラウドをおよそ19カ月にわたり提供し198名に自由に利用してもらい,結果を分析した.検証の結果,提案するプライベートクラウドの利用モデルにより職場のコミュニケーションが活性化したり,プライベートクラウドを中心とした価値の流通や再利用が見られるなど,企業内の業務が改善されることを実証した.さらに,効果的なプライベートクラウドを提供するためのポイントを明らかにした.The use of cloud computing is expanding steadily. Especially public cloud, which is used from public access, has already used in various fields, and there are a lot of case studies of utilizing the characteristic features of cloud. On the other hand, most of the case studies of private cloud in companies focus on the cost effectiveness of cloud. In this study, we propose and evaluate a practical use model of private cloud in companies, in which we make use of `on-demand and self-service' characteristic on cloud. The evaluation method is providing a practical IaaS private cloud for 19 months which is used by 198 workers, and analyzing the results of usage. As a result of the evaluation, we found that private cloud is capable of making some characteristic improvements such as facilitating communication and circulating values via private cloud. Furthermore, we clarified some points for providing effective private cloud.
