Synnefo is a complete open source cloud stack written in Python that provides |
7 |
Compute, Network, Image, Volume and Storage services, similar to the ones |
8 |
offered by AWS. Synnefo manages multiple `Ganeti |
9 |
<http://code.google.com/p/ganeti>`_ clusters at the backend for handling of |
10 |
low-level VM operations and uses `Archipelago |
11 |
<http://www.synnefo.org/docs/archipelago/latest/>`_ to unify cloud storage. To |
12 |
boost 3rd-party compatibility, Synnefo exposes the OpenStack APIs to users. |
13 |
|
14 |
Synnefo powers GRNET's `~okeanos public cloud service |
15 |
<http://okeanos.grnet.gr>`_ and you can try it out live at `demo.synnefo.org |
16 |
<http://demo.synnefo.org>`_. |

Synnefo has three main components providing the corresponding services: |

Pithos: File/Object Storage service <pithos> |
25 |
Cyclades: Compute/Network/Image/Volume services <cyclades> |

This is an overview of the Synnefo services: |

32 |
Synnefo is designed with simplicity, scalability and stability in mind. |
33 |
Furthermore, although it can be deployed in small configurations, it was |
34 |
initially designed to address large installation problems. |
35 |
|
36 |
All Synnefo components use an intuitive settings mechanism, that adds and |
37 |
removes settings dynamically as components are getting added or removed from a |
38 |
physical node. All settings are stored in a single location. |

Synnefo General Architecture |
44 |
============================ |
45 |
|
46 |
The following figure shows the whole Synnefo stack and how it interacts with |
47 |
multiple Ganeti clusters and the storage backends. Synnefo decouples the cloud |
48 |
from the cluster layer enhancing robustness, scalability, and ease of |
49 |
administration and upgrades without impacting VM stability. As shown in the |
50 |
figure below, Synnefo sits on the cloud layer: |
51 |
|

:target: _images/snf-architecture.png |
54 |
|
55 |
Synnefo manages multiple Ganeti clusters and different storage backends |
56 |
(e.g., Ceph/RADOS or NFS-based backends as shown in the figure). |
57 |
|

For an extensive view of all components, the interconnection and APIs between |
59 |
them, please take a look at the Admin Guide's :ref:`corresponding figure |

Synnefo Guides |
64 |
============== |
65 |
|
66 |
There are 4 guides for Synnefo. |
67 |
|
68 |
The Quick Installation guide describes how to install Synnefo on a single node |
69 |
in less than 10 minutes using the `snf-deploy` tool. This kind of installation |
70 |
is targeted for testing and demo environments rather than production usage |
71 |
deployments. It is the perfect way, even for an inexperienced user to have the |
72 |
whole Synnefo stack up and running and allows for a quick preview of the basic |
73 |
Synnefo features. |
74 |
|
75 |
The Admin's Installation guide describes how to install the whole Synnefo stack |
76 |
in just two physical nodes. This guide is useful to those interested in |
77 |
deploying Synnefo in large scale, as a starting point that will help them get |
78 |
familiar with the Synnefo components and overall architecture, as well as the |
79 |
interconnection between different services. This guide explains the whole |
80 |
procedure step by step, without the use of the `snf-deploy` tool. Anyone |
81 |
familiar with this guide, will be able to easily install Synnefo in a larger |
82 |
number of nodes too, or even expand the two node installation dynamically. |
83 |
|
84 |
The Administrator's Guide targets system administrators, who want to dive into |
85 |
more details and common tasks regarding Synnefo. For the experienced Synnefo |
86 |
administrator, there is also a section that describes how to do scale-out |
87 |
Synnefo deployments with corresponding examples. This targets large scale |
88 |
installations of Synnefo. |
89 |
|
90 |
The Developer's Guide targets developers, who want to build on top of Synnefo |
91 |
and so describes all the different types of interfaces Synnefo provides to the |
92 |
external world. Also documents all Synnefo external REST APIs. |
93 |
|
94 |
.. The Integrator's Guide targets developers, who want to actually |
95 |
.. extend/modify/change Synnefo itself, so describes Synnefo's indepth |
96 |
.. architecture and the internals of Synnefo components (currently out-of-date!). |
