The spotlight today is a follow-up to a previous one about Oracle customer KT. In today's spotlight, we have a newly published full success story about KT for you to read! In it, you'll learn how KT increased their operational efficiency, were able to deploy cloud services 50% faster, lowered virtualization overhead, and much more, due to Oracle VM and Oracle Linux.
We'll see you next week!

In the first video, Jung-Sik Suh, SVP of Cloud Convergence at KT, discusses the IT challenges they recently faced. To support their next generation customers, they needed to diversify their product offerings and expand their capacity, and they had to do this while simultaneously merging with another company! They decided to design a private cloud using Oracle VM and Oracle Linux that resulted in a 70% reduction of infrastructure cost and 50% reduction in operation cost.
In the second video, Mr. Suh discusses how implementing an Oracle software stack that is designed to work together, including Oracle VM, Oracle Linux, Oracle Enterprise Manager, and more, allows them to save costs and pass the savings on to their customers, and in the future, will provide a profit center for them, as well.

Happy Friday! During Oracle OpenWorld, we were able to do brief videos with a number of Oracle virtualization and Oracle Linux partners. We have more of these coming soon, but I wanted to highlight some that we just published:

Happy Friday, everyone! With all the discussion about Oracle VM Templates on this blog in the last week or so (here, here, and here), I thought highlighting a short video that summarizes Oracle VM Templates and Oracle Virtual Assembly Builder would be interesting. Click below to watch (it's just under 4 minutes):
See you all next week!

It's time once again for our Friday tip. Our question today is about how to determine how much video RAM to allocate for your virtual machines in a VDI deployment:
How much video RAM do I really need on my VirtualBox VMs?
Answer by John Renko, Consulting Developer, Oracle:
The answer is in the VirtualBox admin guide but it's seldom followed correctly, usually resulting in excess unused RAM to be allocated. The formula for determining how much RAM to allocate is shown below for a 32 bit fullscreen 22" monitor supporting 1680x1050:
bit depth / 8 x horizontal res x vertical res / 1024 / 1024 = MB RAM
Which translates to:
32 bits / 8 x 1680 x 1050 / 1024 / 1024 = 6.7 MB
If you wanted to support dual 22" monitors, you would need twice that, so 13.4 MB.
Anything in excess of what is needed is readily allocated but not used and would be better suited for running more VMs!
Thanks John, that tip should help folks squeeze a little more out of their VDI servers. And remember, if you have a question for us, use hash tag #AskOracleVirtualization on Twitter.
We'll see you next week with another tip!

The Oracle virtualization team is back from a very successful Oracle OpenWorld! Hopefully you were able to come to the show and talk with our virtualization experts at the demo booths or in our sessions. But if you didn't, you can get a summary of what we talked about from a number of short videos. In this post, we're going to highlight the Oracle OpenWorld Live videos, and in a future post we'll cover the videos we shot ourselves (once we get them all posted!).
If you missed it, Oracle OpenWorld Live carried keynotes and interviews with all kinds of folks during the show. They also archived these segments so you can watch them at your leisure. I've gone through the videos and selected some that highlight virtualization:
- Edward Screven on mission critical clouds.
- Wim Coekaerts talks virtualization.
- Rex Wang on Oracle Cloud.
- Ronen Kofman on Oracle VM Templates.
- Chris Kawalek on Oracle's desktop virtualization software.
- Chris Kawalek discusses Oracle Sun Ray Clients.
If we missed you this year, we hope to see you at OpenWorld 2013!

We're currently at BriForum London 2012, and we're demoing the Oracle desktop virtualization portfolio. Oftentimes at trade shows, all of the Oracle Applications you're seeing are hosted by Oracle desktop virtualization. This lets us do things like show how you can instantly switch a Siebel session from a desktop PC to an iPad for working on the go, or using applications from literally "any old PC" just by logging in with a web browser.
This show is exclusively focused on desktop virtualization, so we were able to create a demo that highlights some of the cooler features of the portfolio. Here are some things we're showing:
- Impeccable full screen, high definition video from a virtual desktop on a large plasma display. Standing directly in front of the display, it's difficult to tell the video is originating on a virtualized operating system on a server, and the view of that entire desktop is flowing over the wire to a very inexpensive thin client that has no local operating system and requires no management. It's pretty much indistinguishable from video you'd see by hooking a high powered PC to a plasma display.
- A new feature in our latest releases is location awareness. This allows applications on the virtualized desktop to (optionally) access information about which particular client or device a user is logging in from. This is essential in industries like healthcare, where whenever something is logged about a patient, not only is the identity of the person doing the logging crucial, but where the person physically was when they did the logging is also required. Developers can use this information in other really cool ways, for example, making it so when a user prints from a particular place, the print job is sent to the printer physically closest to the user. In the demo here, we're showing location awareness by changing the desktop image to indicate the user's location with a dot on a map on the desktop wallpaper. So, login to one Sun Ray Client and you get a red desktop with the dot in room x, login to a different one and you get a blue desktop with the dot in room y. Very cool stuff.
- Multiple desktop environments across two monitors. This is something that people are getting used to with client side hypervisors (such as Oracle VM VirtualBox), but it's very innovative with server based desktop virtualization. The idea here is that, from a single client device, you can login to two different server side environments and access both simultaneously. This is ideal for developers and other users who might need to balance their time in multiple operating systems.
- Speaking of multiple operating systems, since Oracle Virtual Desktop Infrastructure uses Oracle VM VirtualBox as the virtualization engine, users can run not only Windows desktops like other solutions, but can also run Ubuntu, Oracle Linux, and Oracle Solaris virtual desktops. Those are the operating systems that are tested, but in actuality, lots and lots of operating systems can work, too (at your own risk, of course). So, as an experimental demo, we're showing virtual desktops on operating systems going all the way back to Windows 3.1. Yes, Windows 3.1 from 1992 in a modern virtual desktop infrastructure. Not for the feint of heart, but fun to show, just the same.
- Accessory devices that use USB have historically been difficult for desktop virtualization, thin clients, etc. But today, our solution provides excellent support for USB devices. At the booth here, we're showing a couple of devices connected through the USB ports on a Sun Ray 3 Client, and communicating with a server side Windows XP environment. The first is a digital camera with a remote capture application on the Windows virtual desktop...press a button in the Windows virtual desktop and it sends a commands over the wire to the Sun Ray Client, Sun Ray Client sends to the camera via USB, camera takes the picture, and then uploads the picture by reversing the path back to the server. And, even more interesting is a remote sensor device used in education. This device samples information from the environment (sound levels, temperature, etc.), and sends it as a stream over USB to a Windows application, again, installed on the virtual desktop at the server.
If you happen to be at BriForum in London, please take a moment to stop by the booth and let us show you around the portfolio. You might be surprised what we can do!

As my boss, Wim Coekaerts pointed out on his blog yesterday, there are a number of good, educational videos covering Oracle VM on YouTube, including coverage of some topics for Oracle VM 2.2 (the latest release). Very easy to find, just go to YouTube and search on Oracle VM (or Oracle VM 2.2 to see those specifically). Of course, you'll also find some videos on reference customers, partners, and even a video interview with me from the Cloud Computing Expo that I mentioned in my earlier blog entry.
Thanks to the Oracle Partner Network team for producing these fine videos!
