I have a layered architecture to be drawn in a paper. The architecture looks similar to the one below.

enter image description here

How to draw something like this?

What I have so far:

\begin{tikzpicture}[stack/.style={rectangle split, rectangle split parts=#1,draw, anchor=center}]
\node[stack=5]  {
\nodepart{two}a
\nodepart{three}a
\nodepart{four}c
\nodepart{five}d
};
\end{tikzpicture}

How do I split a layer to have two boxes?

While code snippets are useful in explanations, it is always best to compose a fully compilable MWE that illustrates the problem including the \documentclass and the appropriate packages so that those trying to help don't have to recreate it. This is especially important for tikz as there are numerous libraries. –  Peter Grill Mar 15 '13 at 0:31

You can use the following code as a starting point (a complete and improved version, as well as an explanation of the code, can be found below):

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{positioning}

\definecolor{mybluei}{RGB}{124,156,205}
\definecolor{myblueii}{RGB}{73,121,193}
\definecolor{mygreen}{RGB}{202,217,126}

\pgfdeclarelayer{background}
\pgfsetlayers{background,main}

\begin{document}

\begin{tikzpicture}[node distance=3pt,
blueb/.style={
  draw=white,
  fill=mybluei,
  rounded corners,
  text width=2.5cm,
  font={\sffamily\bfseries\color{white}},
  align=center,
  text height=12pt,
  text depth=9pt},
greenb/.style={blueb,fill=mygreen},
]
\node[blueb] (RCP) {RCP main};
\node[blueb,right=of RCP] (Aut) {Authoring};

Here's now an improved version in which I am using the code from Jake's answer to Creating a node fitting the horizontal width of two other nodes. In this new version, some values that were hard-coded (in fact, mostly guessed) in the previous version are now automatically calculated.

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{positioning,calc,fit}

\definecolor{mybluei}{RGB}{124,156,205}
\definecolor{myblueii}{RGB}{73,121,193}
\definecolor{mygreen}{RGB}{202,217,126}
\definecolor{mypink}{RGB}{233,198,235}

% this length is used to control the width of the light blue frame
% for the upper part of the diagram
\newlength\myframesep
\setlength\myframesep{8pt}

\pgfdeclarelayer{background}
\pgfsetlayers{background,main}

\pgfkeys{
    /tikz/node distance/.append code={
        \pgfkeyssetvalue{/tikz/node distance value}{#1}
    }
}

\newcommand\widernode[5][blueb]{
\node[
        #1,
        inner sep=0pt,
        shift=($(#2.south)-(#2.north)$),
        yshift=-\pgfkeysvalueof{/tikz/node distance value},
        fit={(#2) (#3)},
        label=center:{\sffamily\bfseries\color{white}#4}] (#5) {};
}

\begin{document}

\begin{tikzpicture}[node distance=3pt,outer sep=0pt,

\end{tikzpicture}

Explanation of the code

The first step is to notice that the diagram consists of just one basic shape: a rectangular node with rounded corners, a filling color, a color for the border, with text centered, and the text is white and in sans-serif font, so the thing to do is to define a style with this characteristics:

\documentclass{article}
\usepackage{tikz}

\definecolor{mybluei}{RGB}{124,156,205}

\begin{document}

\begin{tikzpicture}[node distance=3pt,outer sep=0pt,
blueb/.style={
  draw=white,
  fill=mybluei,
  rounded corners,
  text width=2.5cm,
  font={\sffamily\bfseries\color{white}},
  align=center,
  text height=12pt,
  text depth=9pt},
]
\node[blueb] (RCP) {RCP main};
\end{tikzpicture}

\end{document}

enter image description here

The next step is to position the nodes, and this can be done with the help of the positioning library; here's a portion of the diagram illustrating this:

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{positioning}

\definecolor{mybluei}{RGB}{124,156,205}
\definecolor{myblueii}{RGB}{73,121,193}
\definecolor{mygreen}{RGB}{202,217,126}
\definecolor{mypink}{RGB}{233,198,235}

\begin{document}

\begin{tikzpicture}[node distance=3pt,outer sep=0pt,
blueb/.style={
  draw=white,
  fill=mybluei,
  rounded corners,
  text width=2.5cm,
  font={\sffamily\bfseries\color{white}},
  align=center,
  text height=12pt,
  text depth=9pt},
greenb/.style={blueb,fill=mygreen},
]
\node[blueb] (RCP) {RCP main};
\node[blueb,right=of RCP] (Aut) {Authoring};
\node[blueb,right=of Aut] (Bro) {Browsing};
\node[blueb,below=of RCP] (RTe) {Rich Text};
\node[blueb,below=of RTe] (Com) {Common};
\node[blueb,fill=mypink,below=of Com] (Jti) {Jtidy};
\end{tikzpicture}

\end{document}

enter image description here

The next step is to place the "wider" nodes and it is here that Jake's answer is used; I defined a new command \widernode with four mandatory arguments (the first two are the nodes used to control the size (See the linked answer for details), the third one gives the label and the fourth one, the string used to name the node) and one optional argument (to control the attributes of the node):

\pgfkeys{
    /tikz/node distance/.append code={
        \pgfkeyssetvalue{/tikz/node distance value}{#1}
    }
}

\newcommand\widernode[5][blueb]{
\node[
        #1,
        inner sep=0pt,
        shift=($(#2.south)-(#2.north)$),
        yshift=-\pgfkeysvalueof{/tikz/node distance value},
        fit={(#2) (#3)},
        label=center:{\sffamily\bfseries\color{white}#4}] (#5) {};
}

The above will require the calc and fit libraries. Now we can automatically build the wider nodes using other nodes as reference:

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{positioning,calc,fit}

\definecolor{mybluei}{RGB}{124,156,205}
\definecolor{myblueii}{RGB}{73,121,193}
\definecolor{mygreen}{RGB}{202,217,126}
\definecolor{mypink}{RGB}{233,198,235}

\pgfkeys{
  /tikz/node distance/.append code={
    \pgfkeyssetvalue{/tikz/node distance value}{#1}
  }
}

\newcommand\widernode[5][blueb]{
  \node[
    #1,
    inner sep=0pt,
    shift=($(#2.south)-(#2.north)$),
    yshift=-\pgfkeysvalueof{/tikz/node distance value},
    fit={(#2) (#3)},
    label=center:{\sffamily\bfseries\color{white}#4}] (#5) {};
}

\begin{document}

\begin{tikzpicture}[node distance=3pt,outer sep=0pt,
blueb/.style={
  draw=white,
  fill=mybluei,
  rounded corners,
  text width=2.5cm,
  font={\sffamily\bfseries\color{white}},
  align=center,
  text height=12pt,
  text depth=9pt},
greenb/.style={blueb,fill=mygreen},
]
\node[blueb] (RCP) {RCP main};
\node[blueb,right=of RCP] (Aut) {Authoring};
\node[blueb,right=of Aut] (Bro) {Browsing};
\node[blueb,below=of RCP] (RTe) {Rich Text};
\widernode{Aut}{Bro}{Library Managemet}{LMa}
\node[blueb,below=of RTe] (Com) {Common};
\node[blueb,fill=mypink,below=of Com] (Jti) {Jtidy};
\end{tikzpicture}

\end{document}

enter image description here

Next we add the frame for the upper part using layers, as in:

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{positioning,calc,fit}

\definecolor{mybluei}{RGB}{124,156,205}
\definecolor{myblueii}{RGB}{73,121,193}
\definecolor{mygreen}{RGB}{202,217,126}
\definecolor{mypink}{RGB}{233,198,235}

% this length is used to control the width of the light blue frame
% for the upper part of the diagram
\newlength\myframesep
\setlength\myframesep{8pt}

\pgfdeclarelayer{background}
\pgfsetlayers{background,main}

\pgfkeys{
  /tikz/node distance/.append code={
    \pgfkeyssetvalue{/tikz/node distance value}{#1}
  }
}

\newcommand\widernode[5][blueb]{
  \node[
    #1,
    inner sep=0pt,
    shift=($(#2.south)-(#2.north)$),
    yshift=-\pgfkeysvalueof{/tikz/node distance value},
    fit={(#2) (#3)},
    label=center:{\sffamily\bfseries\color{white}#4}] (#5) {};
}

\begin{document}

\begin{tikzpicture}[node distance=3pt,outer sep=0pt,
blueb/.style={
  draw=white,
  fill=mybluei,
  rounded corners,
  text width=2.5cm,
  font={\sffamily\bfseries\color{white}},
  align=center,
  text height=12pt,
  text depth=9pt},
greenb/.style={blueb,fill=mygreen},
]
\node[blueb] (RCP) {RCP main};
\node[blueb,right=of RCP] (Aut) {Authoring};
\node[blueb,right=of Aut] (Bro) {Browsing};
\node[blueb,below=of RCP] (RTe) {Rich Text};
\widernode{Aut}{Bro}{Library Managemet}{LMa}
\node[blueb,below=of RTe] (Com) {Common};
\node[blueb,fill=mypink,below=of Com] (Jti) {Jtidy};
\begin{pgfonlayer}{background}
\draw[blueb,draw=black,fill=mybluei!40] 
  ([xshift=-\myframesep,yshift=3\myframesep]current bounding box.north west) 
    rectangle 
  ([xshift=\myframesep,yshift=-\myframesep]current bounding box.south east);
\end{pgfonlayer}
\end{tikzpicture}

\end{document}

enter image description here

And the rest is now easy; just to add the lower node (Java Runtime) and the title.

Honestly, TikZ's syntax with ... = of ... is more elegant than the tabular-like syntax adopted by psmatrix. –  In PSTricks we trust Mar 15 '13 at 15:49

Instead of placing every node one after the other, like in great Gonzalo's answer, you could use a matrix. The problem with TikZ's matrix is that it's not possible to draw \multicolumn nodes like in tabular. Therefore we have to draw only regular nodes inside the matrix and later draw wider (or taller) nodes.

Let's start with the matrix. It's a matrix of nodes with box nodes. All positions occupied with wider nodes are empty but nodes on empty cells will fill them with nodes that will later be used to drawn wider ones. First row is almost empty except for title node. With it it won't be necessary to use background layers.

We use a matrix of nodes (provided by matrix library) because it's easier syntax. And with |[box=mypink]| Jtidy it's possible to change already defined options. row 1\.style is another way of specifying special conditions for matrix cells.

\matrix (stack) [draw,
      column sep=3pt, row sep=3pt,%
      matrix of nodes,% 
      nodes={box, outer sep=0pt, anchor=center, inner sep=3pt},%  
      row 1/.style={nodes={fill=none,draw=none,minimum height=3mm}},
        nodes in empty cells,
]

Black line around nodes is the border of the matrix. It's the area that later will be filled. Title node it's not seen because it's typed with white.

Now with a \widernode command similar to the one used by Gonzalo, it's easy to place wider nodes over the regular ones.

\newcommand\widernode[5][widebox]{
  \node[
    #1,
    fit={(#2) (#3)},
    label=center:{\sffamily\bfseries\color{white}#4}] (#5) {};
}

As you can see \widernode is simpler because it use matrix nodes as reference.

\widernode{stack-3-2}{stack-3-3}{Library Management}{LMg}
\widernode{stack-4-2}{stack-4-3}{UMA}{UMA}
\widernode{stack-4-4}{stack-4-5}{Export/Import}{ExImp}
\widernode[widebox=mygreen]{stack-5-2}{stack-5-3}{EMF}{EMF}
\widernode[widebox=mygreen]{stack-6-1}{stack-6-5}{RCP Runtime}{RCPrun}

enter image description here

Now as matrix is already a node we can give it a node appearance with \matrix (stack) [boxstyle=mybluei!40

enter image description here

But we want a wider margin between nodes and matrix border, so we introduce a inner sep=4mm, in matrix options. The problem is that it will also applied to inner nodes (matrix cells). To avoid it a new inner sep=3pt is used inside nodes declaration.

enter image description here

Now only Java runtime node is left. We can also use fit to fix it's width and place 3pt below EPF composer:

\node [fit={(stack.south west)(stack.south east)},
       boxstyle=myblueii,draw=black,inner sep=0pt,
       below=3pt of stack.south,anchor=north,
       label={[mylabel]center:Java Runtime}] (JavaR) {};

And that's all. The final result is:

And the complete code:

\documentclass[border=3mm]{standalone}
\usepackage{tikz}
\usetikzlibrary{positioning,fit,matrix}

\definecolor{mybluei}{RGB}{124,156,205}
\definecolor{myblueii}{RGB}{73,121,193}
\definecolor{mygreen}{RGB}{202,217,126}
\definecolor{mypink}{RGB}{233,198,235}

\newcommand\widernode[5][widebox]{
  \node[
    #1,
    fit={(#2) (#3)},
    label=center:{\sffamily\bfseries\color{white}#4}] (#5) {};
}
