+ITシステムが巨大化していくにつれ, 障害発生事例が社会に与える影響もより大きな物となる.
+それに伴い, ITシステムにおけるディペンダビリティへの注目が増している.
+
+そこで, DEOSプロジェクトはITシステムにおけるディペンダビリティを担保する技術体系をまとめ, 制度化, さらには事業化を目指している.
+DEOSプロジェクトは2006年に独立行政法人科学技術機構(JST)はCRESTプログラムの1つとして始まったプロジェクトである.
+DEOSプロジェクトは, 変化し続ける目的や環境の中でシステムを適切に対応させ, 継続的にユーザが求めるサービスを提供することができるシステムの構築法を
+開発することを目標としている\cite{deos2013}.
+DEOSプロジェクトではそれらの技術体系を「オープンシステムディペンダビリティ」として定義し, それをDEOSプロセスとしてまとめた(図\ref{fig:deos_proccess}).
+
+\begin{figure}[htpb]
+  \begin{center}
+    \includegraphics[scale=0.5]{figures/deos_proccess.pdf}
+    \caption{DEOS プロセス}
+    \label{fig:deos_proccess}
+  \end{center}
+\end{figure}
+
+DEOSプロセスには変化対応サイクルと障害対応サイクルの2つのサイクルがある.
+変化対応サイクルは上流プロセスにおける対象システムのオープンシステムディペンダビリティを担保するためのプロセスである.
+障害対応サイクルは対象システムの運用時に必要とされるプロセスである.
+DEOSプロセスは企画や設計という上流からシステム運用までの対象システムのライフサイクル全体に係わる.
+対象システムの運用は, ステークホルダからの対象システムに対する要求に関する
+合意を始めとしたあらゆる議論に関する合意をベースに行われる.
+
+DEOS プロセスを構成している各(サブ)プロセスからアクセスが行われるデータベースとして D-ADD(DEOS Agreement Description Database)がある\cite{d_add2013}.
+%DEOS プロセスにおいて, 全てのデータを保持する D-ADD(DEOS Agreement Description Database) と呼ばれるデータベースがある.
+D-ADD はステークホルダ合意と対象システムに存在するプログラム・コード, 及び対象システムの運用状態との間の一貫性を常に保つための機構を提供する.
+このようなデータベースは様々なデータを柔軟に格納する必要があり, データベーススキーマの頻繁な変化に対応する必要がある.
+%そのためには木構造を直接使えるデータベースが必須である.
+これらのデータベースは, ウェブからアクセスされることも想定される.
+そのため, DEOSはウェブサービスとして捉えることができる.
+
 ウェブサービスにとってデータベースは必須であり, ウェブサービスの規模
 に比例してデータベースへの負荷も大きなものとなっている. 
 そのため, データベースの処理能力の高さはそのままウェブサービスの質にも繋がってくる重要な

-    <h1>研究の背景と目的</h1>
-    <ul>
-	<li>スマートフォンやタブレット端末の普及により、大量のデータを扱うウェブサービスが現れてきている。</li>
-	<li>しかしそれに伴い、サーバサイド側への負荷も増大しウェブサービスがダウンする事態が出てきている。</li>
-	<li>そのため、スケーラビリティはウェブサービスにおいて重要な性質の1つとなっている。</lii>
-	<li>スケーラビリティとは、ある複数のノードから構成される分散ソフトウェアがあるとき、その分散ソフトウェアに対して単純にノード
-	    を追加するだけで性能を線形に上昇させることができる性質である</li>
-	<li>スケーラビリティのあるプログラムについてアーキテクチャの設計から行った</li>
-    </ul>
-  </div>
-
-  <div class='slide'>
-    <h1>研究の背景と目的</h1>
-
-    <ul>
-	<li>当研究室では非破壊的木構造を用いたデータベースである Jungle を開発している</li>
-	<li>非破壊的木構造とは、データの編集の際に一度木構造として保存したデータには触れず、新しく木構造を作成してデータの編集を行うこと</li>
-	<li>Jungle は分散データベースとして設計・実装されているが、分断耐性や永続性といった部分の実装がまだ
-	    行われていない</li>
-	<li>本研究では、Jungle を用いてスケーラビリティをもつアーキテクチャの追求を行う</li>
-    </ul>

-    <h1>ベンチマーク測定環境の構築</h1>
-    <ul>
-	<li>csクラスタ(VM)上で掲示板プログラムを走らせ、ベンチマークをとる</li>
-	<li>Jungle と Cassandra 両方を走らせる環境の構築を行った</li>
-	<h2>問題が発生</h2>
-	<li>Cassandra でConsistencyLevelをいじってもデータを伝搬してくれない</li>
-	<li>Jungle の分散結果が良くならない。圧倒的に遅い。Cassandra の結果の2倍3倍遅くなる</li>
-    </ul>
-  </div>
-
-  <div class='slide'>
-    <h1>問題解決</h1>
-    <ul>
-	<li>Cassandra はConsistencyLevelとは別にReplication factorというレプリケーション(複製)をとるノードの数を指定する項目がある</li>
-	<li>Cassandra のConsistencyLevelはこのReplication factorの数に対して行われる</li>
-	<ul>
-	    <li>Replication factorをNとした場合、ConsistencyLevelをALLにするとこのNの数だけノードに書き込まれるのをまつ</li>
-	    <li>Replication factorをノードの全体の数に合わせてあげるとよい</li>
-	    <li>Replication factorの設定はv1.1くらいまでは設定ファイルでできるが、v1.2からはキースペース生成時に設定するか
-	    ./bin/cassandra-cli を使ってCassandraのデータにアクセスして変更する必要がある</li>
-	</ul>
-	<br>
-	<li>Jungle の結果が悪い原因</li>
-	<ul>
-	    <li>Javaのメモリの量を増やす設定をいれることで解決</li>
-	</ul>
-    </ul>
-  </div>
-
-  <div class='slide'>
-    <h1>単体・複数ノードへの負荷</h1>
-    <ul>
-	<li>クライアント数最大12台。各クライアント5000回のリクエストを出す</li>
-    </ul>
-    <img src="./images/write_bench.png">
-  </div>
-
-  <div class='slide'>
-    <h1>ベンチマーク改良</h1>
-    <ul>
-	<li>Jungleの結果をbldsvで起動した時に近い結果になることが確認できた</li>
-	<li>Cassandra も Jungle のグラフも横ばいになっている。クライアント側からの負荷が足りない。</li>
-	<li>Cassandra の ConsystencyLevel をいじっても結果が変わらないのも負荷が足りないから？</li>
-	<h2>次の課題</h2>
-	<li>クライアント側はKVMで動かしていて現在12台しか無い</li>
-	<li>負荷をかけるプログラムをforkすることでプロセスを増やして負荷を増やすよう改良する必要がある</li>

+	    データベースのスケーラビリティ

+	<p>ウェブサービスにとってデータベースは必須であり、ウェブサービスの規模に比例してデータベースへの負荷も高まる。</p>
+	<p>データベースの処理能力の高さはそのままウェブサービスの質に繋がるため、データベースのスケーラビリティの確保は重要である。</p>
+	<p>スケーラビリティ確保の方法としてデータ分散があるが、分散する方法により性能も変わってくる。</p>
+	<p>ウェブサービスのなかでも、コンテンツマネジメントシステムに合ったスケーラビリティの確保ができるデータベースの開発を行う。</>

+	    ウェブサービスにおけるデータベースの重要性
+    </h1>
+	<p>ウェブサービスへの負荷が高まることは、データベースへの負荷が高まることでもある。</p>
+	<p>データベースの性能が低ければ負荷に耐え切れずサービスはダウンする</p>
+	<p style="text-align:center;">
+	    <img src="./images/service_down.png">
+	</p>
+	<p>そのため、データベースにはスケーラビリティが必要</p>

+    <h1>
+	    スケーラビリティとは
+    </h1>
+	<p>システムが負荷の増大に対して柔軟に拡張して対応できる性質</p>
+	<p>主に次の2つの方法によりシステムはスケールされる</p>
+	<ul>
+	<li><font color="blue">スケールアップ</font>：<br/>高価な単一マシンによる性能アップ</li>
+	<br/>
+	<li><font color="red">スケールアウト</font>：<br/>汎用的なマシンを複数台用意することで性能アップ</li>
+	</ul>
+	<p>分散システムにおいては<font color="red">スケールアウト</font>によりスケーラビリティを高める</p>
+	<p style="text-align:center;">

+
+  <div class='slide'>
+    <h1>
+	    データベースのスケーラビリティ
+    </h1>
+    <p>データベースのスケーラビリティを考えるとき、どういう用途で使用するかを考えるのが重要。</p>
+	<li>例えば、掲示板システムにおいては、書き込みと読み込みが速いことが求められる。</li>
+    <br/>
+    <p>ウェブサービスにおいても、どのようなサービスを行うかによってスケーラビリティの確保の仕方も変わってくる。</p>
+    <p>本研究で開発しているデータベースはコンテンツマネジメントシステム（CMS）を対象としている。</p>
+    <br/>
+  </div>
+
+  <div class='slide'>
+    <h1>
+	   コンテンツマネジメントシステム(CMS)
+    </h1>
+	<p>Webコンテンツを構成するテキストや画像などのデジタルコンテンツを管理し配信するシステム。</p>
+	<li>例：ブログツール、Wiki</li>
+	<p>分散コンテンツマネジメントシステムに求められること。</p>
+	<li>Webコンテンツを分散して管理</li>
+	<li>スケールアウトするシステム</li>
+	<p>データ全体の整合性に遅延がある、結果整合性でもよい。書き込みや読み込みを優先としたデータベースが必要。</p>
+	<p>そこで、非破壊的木構造データベースJungleの開発が行われた。</p>

+	非破壊的木構造の利点	    
+    </h1>
+	<p>非破壊的木構造は通常の木構造である破壊的木構造に比べ、以下のような利点を持つ</p>
+	<ul>
+	    <li>一度作成したデータは変更されない</li>
+	    <li>データが変更されないため自由にコピーを作ることができる(いつでも読み込みが可能)</li>
+	    <li>ロックがすくない。ロックが必要なのは最新のルートノードを登録するときだけ</li>
+	</ul>
+	<p>ロックが少なく、いつでもコピーが可能なことから、非破壊的木構造はスケーラブルなシステムに有用となる</p>

+    <p>ここまでJungleに実装されている非破壊的木構造の利点について述べた。</p>
+    <p>次に、Jungleにおける分散設計について述べる。</p>
+    <p>データ分散を行うにあたり、まず考えることはトポロジーの形成と他のノードからデータの伝搬の仕方である。</p>
+    <p>Jungleはこの問題に対し、ツリートポロジーを形成し、データ編集の際に発生するオペレーションを他のノードに流すことで解決する。</p>
+  </div>
+
+  <div class='slide'>
+    <h1>
+	Jungleトポロジーの形成
+    </h1>
+    <p>Jungleのトポロジー形成には当研究室で開発している並列分散フレームワークAliceを使用する。</p>
+    <p>Aliceは以下の機能が提供されている</p>
+    <ul>
+	<li>複数のノードによる分散トポロジーの設定</li>
+	<li>トポロジー上でのデータアクセス機構</li>
+    </ul>
+    <p>JungleにAliceを組み込み、Jungleのノード同士でトポロジーを形成する。</p>
+    <p>Aliceの機能である他ノードへのデータアクセス機構を使用してデータ分散を行う。</p>
+    </ul>
+  </div>

+  <div class='slide'>
+    <h1>
+	分散設計: データ編集オペレーション
+    </h1>
+    <p>Aliceにより、ネットワークトポロジーの作成と他サーバが持つデータアクセス機構を実装できた。</p>
+    <p>次はどのデータを取得することでデータの分散を行うか考えなければならない。</p>
+    <br>
+    <p>Jungleにはデータ編集に使われるオペレーションがある。</p>
+    <p>データ編集に使われるオペレーションをそのまま他サーバノードへ流すことでデータの分散が行える。</p>
+    <p>オペレーションには次の4つがある</p>
+    <ul>
+	<li>addNewChild:子ノードの追加を行う</li>
+	<li>deleteChildAt:指定したノードの削除を行う</li>
+	<li>putAttribute:子ノードにattributeに追加を行う</li>
+	<li>deleteAttribute:子ノードのattributeを削除する</li>

+  </div>
+
+  <div class='slide'>
+    <h1>
+	データ編集オペレーション
+    </h1>
+    <p>子ノードを追加し、その子ノードにattributeを追加する場合次のノードオペレーションが実行される。</p>

+	<li>[APPEND_CHILD:<-1>:pos:0]</li>
+	<li>[PUT_ATTRIBUTE:<-1,0>:key:mes,value:hello]</li>

+    <p>しかしもう１つ問題がある。複数のノードから書き込まれるデータの整合性を取る方法が必要である。</p>
+    <p>JungleではこれをMergeを使うことで自動的に解決する。</p>
+    <p>Mergeとは2つ以上の変更の結果を受けて1つの変更に変えることである。</p>

+	<p>実験は単体サーバと分散環境下において行い、どちらともCassandraより平均時間が最低でも2倍以上速いという結果を示すことができた。</p>

+	    <li>ある程度の単位で過去のデータの掃除を行いたい</li>
