Synnefo is designed to be as simple, scalable and production ready as possible.


  		





  40
  39
  
    
Furthermore, although it can be deployed in small configurations, its prime


  		





  41
  
  
    
target is large installations. If you are planning for the latter, you should


  		





  42
  
  
    
first be completely aware of what you want to provide, the architecture of your


  		





  43
  
  
    
cluster/s and Synnefo's overall architecture before you start deploying.


  		





  
  40
  
    
target is large installations.


  		





  44
  41
  
    

  		





  45
  
  
    
All Synnefo components use an intuitive settings mechanism, that gives you the


  		





  46
  
  
    
ability to either deploy the above services independently and standalone, or


  		





  47
  
  
    
interconnected with each other, in large configurations.


  		





  
  42
  
    
All Synnefo components use an intuitive settings mechanism, that adds and removes


  		





  
  43
  
    
settings dynamically as components are getting added or removed from a physical


  		





  
  44
  
    
node. All settings are stored in a single location.

Synnefo also supports RADOS as an alternative storage backend for

Files/Images/VM disks. :ref:`Here <syn+archip+rados>` is a graph that shows

The installation overview walks through the synnefo components and defines roles


  		





  68
  
  
    
per node so that each role can be installed separately. Please note that


  		





  69
  
  
    
different roles can still coexist in the same node and there is also a posibility


  		





  70
  
  
    
to install everything on one node. For the sake of scalability this is not recommended.


  		





  71

The quick installation guide describes how to install the whole synnefo stack

The quick installation guide describes how to install the whole Synnefo stack


  		





  73

in just two physical nodes, for testing purposes. This guide is useful to those


  		





  74
  
  
    
interested in deploying synnefo in large scale, as a starting point that will


  		





  75

  77
  
  
    
also provides a quick preview of the basic synnefo features, although we would

like to think that synnefo unveils its real power while scaling.

The Administrator's Guide targets system administrators, who want to dive into


  		





  81
  
  
    
more details and common tasks regarding Synnefo. The Developer's Guide targets


  		





  82
  
  
    
developers, who want to build on top of Synnefo and so describes all the


  		





  83
  
  
    
different types of interfaces Synnefo provides to the external world. The


  		





  84
  
  
    
Integrator's Guide targets developers, who want to actually


  		





  85
  
  
    
extend/modify/change Synnefo itself, so describes Synnefo's indepth


  		





  86
  
  
    
architecture and the internals of Synnefo components.

more details and common tasks regarding Synnefo. For the experienced Synnefo


  		





  
  77
  
    
administrator, there is also a section that describes how to deploy Synnefo in


  		





  
  78
  
    
large scale with a corresponding guide.
