Did you know that you can download FREE, already configured servers from the Internet, then run them on your Windows XP/2003 or Linux VMware computer? These servers can do some amazing things, they are free, and they can be up and running in minutes. Let's find out how...
What do I need to get started?
To use one of these VMware appliances, you will need to download and install either VMware Server or VMware Player. Both of these are free. VMware Player, of course, will only allow you to "play" a virtual machine, not edit its configuration or create new virtual machines.
Also, keep in mind that every virtual machine you run will take resources away from your host system. This is especially true when it comes to RAM. Memory is the most crucial resource on a system that is hosting virtual machines.
What do I need to know about these Virtual Appliances?
There are a few things you should know about these virtual appliances. First off, let's cover the benefits:
- These are complete pre-built servers. That means that the OS and applications already installed and ready for use.
- Once these servers are opened with VMware Server or Player, you can instantly "turn them on" and use them. Installing a new server and enterprise application doesn't get any easier than that!
- 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.
At this point, you might be asking where you can obtain these virtual appliances. The VMware Virtual Appliance Marketplace the best single source I have seen to obtain virtual appliances. The popularity of this database has been amazing. Many vendors and users have contributed their application or their customized appliances.
You should also know that there are Certified Appliances and non-certified. The certified appliances are from software companies that want to demo their software solution and where their appliances has passed a level of testing to ensure it will function and be secure. When other individuals or vendors contribute their appliances, these appliances are non-certified but still may be very useful appliances.
