Synnefo

Welcome to Synnefo's documentation

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

| Synnefo is open source cloud software, used to create massively scalable IaaS

  clouds.

| Synnefo uses `Google Ganeti <http://code.google.com/p/ganeti/>`_ for the low

  level VM management part.

| You can see Synnefo in action, powering GRNET's

  `~okeanos public cloud service <http://okeanos.io>`_.

| It is a collection of components (snf-*), most of them written in python, that

  are used as the building bricks to provide the following services:

.. toctree::

   :maxdepth: 1

   Identity Management (codename: astakos) <astakos>

   Object Storage Service (codename: pithos+) <pithos>

   Compute Service (codename: cyclades) <cyclades>

   Network Service (part of Cyclades) <networks>

   Image Registry (codename: plankton) <plankton>

   Billing Service (codename: aquarium) <http://docs.dev.grnet.gr/aquarium/latest/index.html>

   Volume Storage Service (codename: archipelago) <archipelago>

There are also components for:

   Secure image deployment (snf-image tool) <snf-image>

   Command-line cloud management (kamaki tool) <http://docs.dev.grnet.gr/kamaki/latest/index.html>

   Image bundling/uploading/registering (snf-image-creator tool) <http://docs.dev.grnet.gr/snf-image-creator/latest/index.html>

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

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

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

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

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

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

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

interconnected with each other, in large configurations.

Synnefo General Architecture

============================

The following graph shows the whole Synnefo architecture and how it interacts

with multiple Ganeti clusters. Right click on the image and select "Open image

in new tab" to be able to zoom in.

Synnefo Guides

==============

There are 4 guides for Synnefo.

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

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

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

help them get familiar with the synnefo components and overall architecture, as

well as the interconnection between different services. Such an installation,

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

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

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

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

Integrator's Guide targets developers, who want to actually

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

architecture and the internals of Synnefo components.

List of all Synnefo components

==============================

Here are all Synnefo components. Combined in different ways, they provide all

Synnefo services. All components are released as:
