PC のモバイル化，SNS の爆発的普及に伴い，個人の Web サイトであってもコンテンツ次第でアクセスが集中する機会が増大してきている．我々は，サービス利用者に専門的な知識を要求せず，アクセス数や負荷に応じて反応的かつ高速にリソースをインスタンスに再割当てすることで，サービス利用者や事業者に手間を強いることなく突発的なアクセス集中に耐えうる FastContainer アーキテクチャを提案した．一方で，従来のホスティングサービスやクラウドサービスと同様に，インスタンスの収容サーバ障害時に，HTTP タイムアウトが生じない程度での可用性を担保しサービスを継続提供するためには，複数収容サーバに横断して，それぞれ複数インスタンスを立ち上げておく必要があった．そのため，利用者にとってはサービス利用コストの増加に繋がっていた．本研究では，HTTP リクエスト処理時において，単一のインスタンスであっても，収容サーバの状態に応じて自動的にインスタンスを別の収容サーバに再配置しサービスを継続させる，HTTP リクエスト単位での低コストで高速なインスタンススケジューリング手法を提案する．高速にインスタンスを再配置するために，Web サーバソフトウェア自体を拡張することなく，Web サーバプロセス起動時に実行されるシステムコールを監視して，起動完了する直前のシステムコール実行前の段階でプロセスイメージを作成しておくことにより，インスタンス再配置時には高速に Web サーバプロセスをそのイメージから起動させる．","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","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":"2018-06-21","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"1","bibliographicVolumeNumber":"2018-IOT-42"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-19T00:56:16.330643+00:00","id":190294,"links":{}}
