LINEではオンプレミスのインフラ拠点を国内外に複数持ち、物理サーバー数4万台超、インターネットトラフィックで1Tbpsを超える規模のインフラを運用しています。
サービスの成長と多角化により毎年30%程度のペースでインフラの拡大が続いています。

そのインフラ上に、日々多種多様なアプリケーションのデプロイがなされており、アプリケーションを開発・デプロイするエンジニアは世界10拠点以上にまたがり、総勢2500名を超えています。
このようなインフラ・開発エンジニアの規模では、開発エンジニアがインフラ構成を意識したデプロイをすることは、学習コストと運用コストが極めて高くなります。

インフラ開発エンジニアはアプリケーションとその動作環境であるインフラをシームレスにつなぐために、ソフトウェアの技術と手法を用いて、インフラのプロビジョニングとオペレーションの自動化とそれらを可能にするためのプラットフォームに責任を持ちます。

このポジションで採用された方は、LINEのPrivate CloudであるVerdaの中で特にOSS(OpenStack, Kubernetes、Rancher)を自社向けにカスタマイズやトラブルシューティング等の業務を担当することになります。

複数台の大規模OpenStackクラスタを運用する上での課題の解決

Private Cloudを取り巻くソフトウェアのトラブルシューティング (OpenStack, Libvirt, QEMU, Dnsmasq, Kubernetes)
