VMware enables you to run a Virtual Machine, which is VMware's version of an emulated state of Windows, Linux, or FreeBSD. You heard me right-on VMware, not only can you do Windows, but also Linux and FreeBSD. That means if you need to test out that new version of Linux, but you don't want to format your drive just to test it out, VMware can just create a virtual drive and you're on your way to seeing what the latest version of your favorite distribution has to offer.
To date, VMware has been pretty much a development product, but thanks to demand for a stable, versatile operating environment, VMware has upped the ante and created their best version of VMware yet-2.0.2.
If you've used a package like Connectix VirtualPC for the Macintosh PowerPC, you'll notice many likenesses it shares with VMware. The website may really hype VMware up and make it sound like there is no loss of performance, but the simple fact is that you do lose clock speed, RAM and hard disk speed, just like you would with any piece of emulation software.
In fact, you can tell both VMware and VirtualPC are designed along the same lines. The configuration is much the same, except one is obviously more PC-fied, while one is more Mac-centric.
Although, what it comes down to is compatibility. VMware does a much better job at emulating x86 hardware, probably since it's operating on top of x86 hardware. That's a logical assumption, right? Enough with guesswork, let's take a look at what's really going on.
Here we see how it really works. A typical PC works like we see on the left. I think the diagram oversimplifies things in a way, but it will do the job.
Essentially, VMware interfaces directly with most your system hardware, which is one way it achieves pretty good performance even on low-end machines. Don't get me wrong, you still won't get the full speed of your PC out of VMware, this happens because things like the hard disk access (where it looks to be hurting the most) are still done through the operating system.
This is how it all happens. This diagram shows you the devices which need VMware still needs to call through the OS-disk, memory and CPU.
Once again, VMware has a few tricks up its sleeve. One great thing about VMware is that you can utilize your local network to get access to your Windows or Linux filesystem. In fact, you can even use a regular network along with your local network at the same time, so you don't need to sacrifice anything with the networking setup.
PALO ALTO, Calif., May 24 /PRNewswire/ -- VMware, Inc., the leading provider of application and service delivery platforms based on innovative virtual machine technology, today announced the closing of a $20 million strategic financing round led by Dell.
VMware launched its first product in May 1999 -- software for desktop personal computers that enables a single PC to simultaneously run multiple, protected sessions with any combination of Linux, Windows NT, Windows 2000 and other Intel based operating systems. Today, VMware has more than 385,000 registered users, and is licensed in 5,000 corporations, in more than 100 countries. The company will use the funds to accelerate the development and deployment of server-based products for providers of hosted applications and services over the Internet or corporate intranets.
"We see VMware as a significant emerging technology in the computing industry," said Jim Totton, Dell's vice president of worldwide software development. "Dell continues to invest in technologies that show strategic potential in the marketplace."
"This financing positions VMware to move into the next phase of growth and evolution of our business strategy: deploying VMware virtual machine technology as a platform for Internet commerce and infrastructure," said Diane Greene, a co-founder and chief executive officer of VMware. "We expect the investment to have a huge impact on our current desktop business as well as speeding time to market for our server products."
VMware's server products will address some of the most critical issues facing providers of hosted applications and services. These include how to guarantee security on shared servers, maintain the stability of existing servers when adding new applications and services and overcome the incompatibility of Linux, Windows NT and Windows 2000. "Today's solution -- a server for each application, service or customer -- is not only expensive, but creates enormous systems administration and management problems," said Greene.
