  5. Copyright@2015 NTT corp. All Rights Reserved. 動機、と、(ちょっと)宣伝 24/365無停止を実現するためのソフトウェア技術  Consistent-Hashベースのスケール性能に優れた負荷分散構成

     障害時にもステート/キャッシュを失わないレプリケーション  大規模災害でもサービスを止めないDisaster Recovery 通信システム以外で面白い使い方、出来ない?? NetroSphere構想:キャリアネットワークのあり方を変革する新R&Dコンセプトを策定 http://www.ntt.co.jp/news2015/1502/150219a.html
  6. Copyright@2015 NTT corp. All Rights Reserved. 要するに アイデア募集中!  頻繁にDBに書きに行く必要がある企業情報システムとか

     スピード!リアルタイム!なソーシャルゲームとか  課金処理とかやりたいeコマースとか ちょっと尖ったアプリケーション開発に如何ですか? × =? lattice

    • https://github.com/cloudfoundry-incubator/lattice#clustered-deployment • provider = AWS (東京リージョン) • lattice version = v0.2.5 + v0.4.0(new!) • terraform version = 0.5.3 • docker version = 1.7.1 •Lattice cellのNW構造チェック • ひたすらifconfig •php::http_get(another_container_IP)で コンテナ間通信が出来るか確認 • docker image : kshino/lattice-php-cluster • phpinfo()でIPアドレスを確認 • $_ENV[“CF_INSTANCE_IP”] : VMのIPアドレス • $_SERVER[“SERVER_ADDR”] : コンテナのIPアドレス • HTTP_GETで?ip=xxx.xxx.xxx.xxxを渡すと、http_get(xxx.xxx.xxx.xxx)が動く
