ConPaaS: an integrated runtime environment
                   for elastic Cloud applications
                       http://www.conpaas.eu


Introduction
============

ConPaaS aims at simplifying the deployment and management of
applications in the Cloud. In ConPaaS, an application is defined as a
composition of one or more services. Each service is an elastic
component dedicated to the hosting of a particular type of
functionality. A service can be seen as a standalone component of a
distributed application.

Each ConPaaS service is self-managed and elastic: it can deploy itself
on the Cloud, monitor its own performance, and increase or decrease
its processing capacity by dynamically (de-)provisioning instances of
itself in the Cloud. Services are designed to be composable: an
application can for example use a Web hosting service, a database
service to store the internal application state and a file storage
service to store access logs. Application providers simply need
to submit a manifest file describing the structure of their
application and its performance requirements.

ConPaaS currently contains:
 
- A web frontend that can be installed within or outside the
  Cloud. This is the website that developers can use to create, delete
  and manage applications in ConPaaS.

- A web service called ConPaaS Director which provides a RESTful API
  to ConPaaS. The web frontend and the command line client use this
  web service as their backend.

- One service dedicated to hosting static Web content as well as Web
  applications written in PHP or Java.

- One service dedicated to hosting MySQL databases.

- One service dedicated to XtreemFS volumes.

- One service for executing arbitrary applications (the so-called “Generic
  service”).

- More services are currently being developed. They will be released
  as soon as they are reasonably well tested and integrated with the
  frontend.


Installation

Bugs

No matter how carefully we have tested this system, it most certainly
still contains a number of remaining bugs. If you encounter any
abnormal behavior, please let us know at info@conpaas.eu.
