A Cloud in Cyclozzo's terms is a cluster, running services which manage database, file system, and application instances. Cyclozzo has a System Cloud exclusively to manage other Application clouds (Application Clouds host your GAE Compatible apps). Each Cloud can be configured to have its own Load Balancer with fail over. Applications hosted can have their own public domain names using any preferred third party DNS service.
System Cloud's main functionality is to deploy Application Clouds, which involves PXE booting a set of machines and associating them with roles (Manager/AppServer).
Although Cyclozzo could be configured to run in just two machine cluster, We recommend the specs mentioned above.

Cyclozzo's Opensource Edition allows you to run Google App Engine compatible applications in a distributed environment. It lacks the features of the proprietary version such as automatic scaling, load balancing, metrics collection, management UI etc. Using Cyclozzo OSE, you will be able to create a cluster where you can host your applications. Cyclozzo's opensource version only provides the yellow colored layer in the Application Cloud diagram.

Cyclozzo's build system can build
deb packages from the sources. Once you have all the dependencies ready in the
deps directory, do
cd cyclozzo/buildbot make all
and publish the debian repository,
Now you'll have an
apt repository with all the packages and dependencies under
ls ../repo i386 all x86_64
You have to share the
repo directory to have anonymous FTP/HTTP access so that
apt can access the packages.
Once the repository is ready, you can add the repository url to all the cluster nodes and install Cyclozzo
sudo add-apt-repository 'deb ftp://<REPOSITORY-ADDRESS-HERE>/all /' sudo add-apt-repository 'deb ftp://<REPOSITORY-ADDRESS-HERE>/x86_64 /' sudo apt-get update sudo apt-get install cyclozzo-ose
NOTE: You may need to enter a password for SSH keys generated during installation. Leave it empty for passwordless SSH access.
First of all you need to select a master node. This is the node from where you control all the other nodes and run commands. Once you are on the master node, issue
sudo nano `cyclozzo --settings`
and change the master and slave node ip addresses. Then do,
to exchange the SSH keys generated during installation to all the slave nodes.
Now, its time to configure/format the cluster
cyclozzo --configure --format all
This command synchronizes the configuration across all the nodes cleans Hadoop Filesystem and Hypertable databases.
cyclozzo --start cluster
cyclozzo --start application --dir guestbook/ --port 8080
