\n
はじめにアジェンダになります。\n読み上げる\n
\n
メモリはいっぱいつかってるけど、CPUはつかってないとか\nディスクIOが欲しくて分散したいとか\nこのサービスのサーバたてすぎちゃったから減らしたいとか。\n
\n
openstackの元となったnasaが開発していたNebulaプロジェクトとは別物\n
\n
\n
\n
\n
\n
\n
\n
\n
\n
\n
\n
\n
AWS知ってる人もいますが、どんなことができるか軽く説明します\n
\n
\n
ロードバランシング機能はまだないですが\n
\n
AWSでいうところのEC2がnovaにあたり、インスタンス作成やEBSの管理などができます\nSwiftはユーザに参照させるようなファイルが保存できるデータストレージ\n本日は核となるNovaのみの説明とさせて頂きます。\n
\n
\n
\n
\n
\n
\n
nova-objectstoreはGlanceに移行途中\n
時間がかかる処理などは非同期処理目的でRabbitMQ\n
\n
\n
FlatManager Centosであげると/etc/network/interfacesが作成されてる\nプロジェクトという単位でユーザやサーバを管理するが、\nVLANManager以外は違うプロジェクトでも同じネットワーク帯域を使うことになる\n
\n
あまり動作しないので\n
eucaツールズはeucalyptusが作った物なんですが、\nopenstackはnova-apiを叩いて処理させるので使うことができる\nもともとopenstackではeucaツールズを使用してインスタンスやボリュームの管理をするようになってます。\n\n
\n
ブロックマイグレーションはサポートされる予定はあるらしい\n
インスタンスからnova-apiへのリクエストは169.254.169.254:80に対して行われるため、これを実際のnova-apiのアドレスへDNATしてあげる必要がある。メタデータにはホスト名とかインスタンス起動タイプ、起動時のキーが入っています。\n
インスタンスの起動やらイメージの管理\n\n
インスタンスの起動停止、\n
\n
\n
\n
インスタンスが自身の情報をCCに取得しにいくが、そもそもそれを知らなかった。取得しにいくIPが169.254.169.254のリンクローカルIPでこれをどうやってCCに渡すか理解できていなかった。CCにIPをつけ、デフォゲをつけiptablesで自身のIPに変換する。ドキュメントが英語で萎えました\nしかも微妙なところもあり、開発者はドキュメントを充実させることが一番のやることといってました。\n
ここまでで15分経過を目安\n
\n
\n
\n
プライベートクラウドを作ってても、一瞬の多くのトラフィックをうける等があった場合AWSも使えるような\n
\n
