  15 +The \textit{reverseproxy} handles the HTTP requests and redirects them to the
  16 +\textit{integration}, the \textit{email} sends and receives e-mails on behalf
  17 +of the platform and the \textit{monitor} keeps the entire environment tracked.
  18 +These three \textit{VMs} mentioned - \textit{reverseproxy}, \textit{email} and
  19 +\textit{monitor} - are accessible via Internet and the other ones are only
  20 +available in the local network created between them.
  21 +
  22 +\textit{Integration} works as a second layer of proxy beneath
  23 +\textit{reverseproxy}, any request to the platform will be handled by it. The
  24 +Colab service provides interface, authentication and search engine integration
  25 +among all the services. When a request is received to a specific service,
  26 +Colab authenticates the user in the target tool, sends the request and makes a
  27 +visual transformation in the HTML page which is the content of the response.
  28 +Another user-oriented feature is the integrated search engine, when the user
  29 +want to find something in the platform Colab will perform the search in the
  30 +whole databases. Colab itself provides a web interface for GNU Mailman and we
  31 +have two others integrated tools in \textit{integration}: Gitlab and Prezento.
  32 +Gitlab provides web interface for Git repositories and issues tracker, and
  33 +Prezento is a front-end for source code static analysis.
  34 +
  35 +The source code static analysis is performed by \textit{mezuro}. It runs some
  36 +static analysis tools on source code stored in repository and provide this data
  37 +to Prezento. A social network and CMS (Content Manager System) is provided by
  38 +Noosfero in \textit{social}, and the databases of all tools with a cache
  39 +service are in \textit{database}.
