Nova Network Strategies
|
||||
-----------------------
|
||||
|
||||
Currently, Nova supports three kinds of networks, implemented in three "Network Manager" types respectively: Flat Network Manager, Flat DHCP Network Manager, and VLAN Network Manager. The three kinds of networks can c-exist in a cloud system. However, the scheduler for selecting the type of network for a given project is not yet implemented. Here is a brief description of each of the different network strategies, with a focus on the VLAN Manager in a separate section.

* For a recommended HA setup, consider a MySQL master/slave replication, with as many slaves as you like, and probably a heartbeat to kick one of the slaves into being a master if it dies.
|

* For performance optimization, split reads and writes to the database. MySQL proxy is the easiest way to make this work if running MySQL.

.. todo:: describe public/private/hybrid/etc
|
||||
|

When you hear terms such as public cloud or private cloud, these refer to the deployment model for the cloud. A private cloud operates for a single organization, but can be managed on-premise or off-premise. A public cloud has an infrastructure that is available to the general public or a large industry group and is likely owned by a cloud services company.
|
||||
|
||||
The NIST also defines community cloud as shared by several organizations supporting a specific community with shared concerns.
|
||||
|
||||
A hybrid cloud can be a deployment model, as a composition of both public and private clouds, or a hybrid model for cloud computing may involve both virtual and physical servers.

Installing the Live CD
|
||||
======================
|
||||
|
||||
If you'd like to set up a sandbox installation of Nova, you can use one of these Live CD images.
|
||||
|
||||
If you don't already have VirtualBox installed, you can download it from http://www.virtualbox.org/wiki/Downloads.
|
||||
|
||||
Download the zip or iso file and then follow these steps to try Nova in a virtual environment.
|
||||
|
||||
http://c0047913.cdn1.cloudfiles.rackspacecloud.com/OpenStackNova.x86_64-2010.1.2.iso (OpenSUSE image; root password is "linux" for this image)
|
||||
|
||||
http://c0028699.cdn1.cloudfiles.rackspacecloud.com/nova-vm.zip (~900 MB) (log in information is nova/nova)
|
||||
|
||||
Once a VM is configured and started, here are the basics:
|
||||
|
||||
#. Login to Ubuntu using ID nova and Password nova.
|
||||
|
||||
#. Switch to running as sudo (enter nova when prompted for the password)::
|
||||
|
||||
sudo -s
|
||||
|
||||
#. To run Nova for the first time, enter::
|
||||
|
||||
cd /var/openstack/
|
||||
|
||||
#. Now that you're in the correct directory, enter::
|
||||
|
||||
./nova.sh run
|
||||
|
||||
.. image:: images/novashvirtually.png
|
||||
|
||||
If it's already running, use screen -ls, and when the nova screen is presented,then enter screen -d -r nova.
|
||||
|
||||
These are the steps to get an instance running (the image is already provided in this environment). Enter these commands in the "test" screen.
|
||||
|
||||
::
|
||||
|
||||
euca-add-keypair test > test.pem
|
||||
chmod 600 test.pem
|
||||
euca-run-instances -k test -t m1.tiny ami-tiny
|
||||
euca-describe-instances
|
||||
|
||||
ssh -i test.pem root@10.0.0.3
|
||||
|
||||
To see output from the various workers, switch screen windows with Ctrl+A " (quotation mark).
