Top 5 VMware Appliances

There are a ton of FREE VMware appliances that just waiting for a click and download. And the best part? They are already configured and ready to run on any Windows XP/2003 or Linux VMware computer!

These servers can do some amazing things, like…

  • Once these servers are opened with VMware Server or VMware Player, you can instantly “turn them on” and use them.
  • These virtual appliances are a great way to demo or test applications. When you are done using it, just delete the virtual disk and the server & application are gone. Or, if you like the application, you can move the whole appliances to a production server.

So where should you start?

Head to the VMware Virtual Appliance Marketplace – one of the best sources for virtual appliances on the Internet. But be sure to pay attention to Certified Appliances and non-certified. The certified appliances are from software companies that want to demo their software solution and where their appliances have passed a level of testing to ensure it will function and be secure.

If you’re at a loss and don’t know which virtual appliance is right for you – check out these Top 5 VMware appliances based on popularity.

  1. Openfiler – a powerful browser based Network Attached Storage appliance. It runs on top of CentOS Linux and supports iSCSI, SMB, NFS, FTP, and other file transfer protocols. You can download the Openfiler NAS appliance here. Openfiler is a free open-source application.
  2. Nagios – an excellent free open-source network monitoring application using the Groundwork open source network monitor, MySQL, and Suse Linux. You can find the virtual appliance for Nagios here.
  3. Cacti – a network performance graphing system. This virtual appliance also offers other applications like syslog and SNMP. You can download the free Cacti appliance at this link.
  4. Fedora Linux – why wait to download it and install it when you can download it “already installed” at this link?
  5. Exchange 2007, others – Microsoft offers a number of virtual machines that can be downloaded from the Internet. While these are designed to run on MS Virtual Server, once downloaded, these can be imported into VMware. For more information on this, checkout our article on how to Download Exchange 2007 Virtual Machines.

N Computing Technology

For more than 1 year a go, I’m addicted with the Virtualization Technology such Microsoft Virtual PC, Vmware… that drive me found lot of knowledge for today technology.

I don’t remember that one day, I’m watching Cambodia TV showing the news that …” Organization has supports and develop the Cambodia Country side to use computer with no electricity there. They provide a computer with less power needs(Solar System) but can share to many user at the same time.. ”

When I heard that, it revise me to the Virtualization technology as Vmware does by virtualize your physical pc to many virtual pc. I’ve try one day to day the ways to make Vmware can share each guest OS to be used on different monitor, Keyboard and mouse.. Finally nothing we can do ! (Vmware doesn’t allow us to run multiple Guest OS with different monitor , key or mouse).

I still not hopeless! Till I found the N Computing Technology that can do what what I want to do. One day look at its website, I could understand and know that we need to buy a complete product suite (Software and Hardware). I have submit through the website in order to try or buy it, but I don’t expect it will be available in Cambodia. Fortunately , about 3 month later there is a Cambodian Guy called me to have an appointment at his office to let me know clearly about NComputing Technology. I really want to know and see the actual working state. But I can’t go that day, cos I’ve gone to my home land.

Few day ago, the same guy called and asked me to their office again.  So yesterday, I went there and see lot of IT guy sitting and listening to the Representative explaining how the product work.

So now I just want to paste all of these to all of you to know about its technology .

Do you have more than one user account on your computer? Maybe there’s a user account for you, a guest, and an administrator. Each person gets their own software, settings, screen colors, and so on, but only one person can use the PC at a time. Until now. NComputing vSpace desktop virtualization software allows multiple user accounts to be used at the same time by efficiently dividing the computer’s resources into independent sessions.

How it works
There are three parts to the NComputing solution.

First is the vSpace software, which allows standard Linux and Windows PCs to be shared by multiple simultaneous users. With vSpace, each person runs their own applications, just as if they had their own PC.
Second is the UXP communications protocol. UXP is the method by which the desktop images and audio are sent to the access device and how the keyboard and mouse data is sent back to the PC. UXP is highly efficient, and excels at multimedia and audio/video synchronization.
Third are the access devices. They are inexpensive, small, low-power, reliable, durable boxes. On one side they plug into the users’ peripherals (such as the keyboard, monitor and mouse). On the other side, they connect via cables to the shared PC.
