Virtual Machine Infrastructure Layout

Deployment

For our first effort, we will set up 3 machines as shown in the diagram above.
We expect that we'll have to do some experimenting to get these "right".
Once we are happy with these 3 VMs and the "application",
we plan to clone the VMs to create a QA, and a PROD environment.

Carinet, please review this section.
Our primitive datacenter BCP plan is as follows.
Whenever we change a VM configuration, we take copy the VM and store it offsite (at the city?).
Should the datacenter fail badly (fire, etc), we provide carinet with the VMs,
and carinet brings up the VMs at another location.
Note that we handle DB backups separately.

Carinet, please review this section.
We plan to move these VMs to our datacenter by midyear 2011.
We want to insure that these VMs are potable.
We expect to do a simple VM copy and do not need v-motion.

Carinet Responsibilities

• Provision hardware
• Provide 3 VMs using barebones VMWare version x.x (todo - need version number)
• install Centos 5 64 bit on each VM
• install Apache web server on the web server VM
• install package manager (yum or Apt-get)

All other software will be installed by city employees.

Security

We assume the following.

• The data center is physically secure.
• VMware installation has latest kernel updates/patches
  Please let us know if any of these assumptions is incorrect.

SE Linux

Do not enable SE Linux.

All VMs shall be accessible via ssh.
The city will provide public keys for those that will have linux root access.

All services shall be disabled unless otherwise requested.

The following shall be disabled:

• NFS
• FTP
• incoming mail

The following shall be enabled.

• outgoing mail
• SSH
• firewall (see below)

Firewall Configuration
