Options for building and deploying Web-based applications to the "cloud" are abundant. Amazon's EC2 offering has been out for a while and offers a variety of operating systems, databases and storage solutions. Linux choices include Red Hat Enterprise Linux, OpenSolaris, Fedora, openSUSE, Gentoo, Oracle Enterprise Linux, Ubuntu and Debian. When you look at the way Amazon prices their options, you'll quickly see that Linux options are significantly cheaper than Windows.

Amazon's application development options are somewhat limited when compared to building things on your own server. You can choose any development platform you'd like as long as it's either Java or Ruby on Rails. The real benefit of choosing Amazon for your cloud provider is their reach and scale. EC2 is not immune to outages as can be attested to by some very high profile Web sites.

New Options

Zimory is a new player in the "cloud computing" space and offers what they feel are a number of unique capabilities. The focus of their service is to provide a hosted environment for any type of Linux virtual appliance. All of the Zimory product offerings are built upon standard hypervisor technologies with support for VMWare Server 1.x, ESX 3.5 and Xen 3.2. You can build your own application appliance and then deploy it to the Zimory cloud as needed.

The second piece of the puzzle that Zimory provides is what they call their Public Cloud Gateway. This piece makes it possible to extend the compute resources of an enterprise on demand in a dynamic way and then scale back down when needed. You really appreciate this level of control when minimizing cost is a key factor your organization. The service is currently in beta and available for testing purposes to interested parties.

Setup and Configuration

Once you have a Zimory account it's a pretty simple process to create a new deployment and provision it to any number of different data centers in the US and Europe. Zimory offers three basic appliances including Ubuntu 8.10 running under VMWare, a Xen-based LAMP appliance based on Debian, and a smaller LAMP version with a limited disk footprint. You can also upload your own appliance as long as it runs under VMWare or Xen.

After you select your appliance you must choose how much memory to provision (between 128 and 8192 MB) and the number of processors you want dedicated to your application. Finally, you must choose a cloud site (or sites) to deploy your image to and you're all done. The Zimory Web-based dashboard gives you a quick summary of your deployments, their status and quick links to start / stop and manage the instance through a browser-based VNC session.

One thing we learned pretty quickly is you'll need the latest Java Runtime for the VNC viewer to work properly. When we attempted to connect to the service from a laptop running Ubuntu 9.04, our Firefox prompted us for the missing plugins and loaded them right up. All that was needed was a quick Firefox restart and we were good to go.
