Virtualization is the process creating a virtual version of a resource such as an operating system, network resource or storage device. Virtualization of an OS involves hosting an OS on another OS using a virtualizer such as Oracle VirtualBox. Various Linux distributions such as openSUSE, Ubuntu, and Fedora are available. In this article we'll discuss hosting openSUSE, Ubuntu, and Fedora on Oracle VirtualBox running on Windows OS.
Setting the Environment
Download the ISO images for the guest OS to be installed, openSUSE 12.1 Live KDE ISO, Ubuntu ISO, Fedora ISO. Download the Oracle VirtualBox exe file VirtualBox-4.1.8-Win.exe or another version from https://www.virtualbox.org/wiki/Downloads. Double-click on the exe file to start the setup wizard. Click on Next in the Oracle VirtualBox 4.1.8 Setup wizard. In Custom Setup select the features to install (the default features) and specify the directory Location to install. Click on Next. Select the required options in Custom Setup and click on Next. A Warning indicates that installing the VirtualBox Networing feature will reset the networking connection. For "Proceed with installation now" click on Yes. In Ready to Install click on Install. Oracle VM VirtualBox gets installed. Select the checkbox Start OracleVM VirtualBox after installation and click on Finish. The Oracle VM VirtualBox Manager gets installed.
In this section we'll install openSUSE distribution on Oracle VirtualBox. Click on Machine>New to create a new virtual machine.
The Create a New Virtual Machine wizard gets started. Click on Next. In VM Name and OS Type specify a Name, and in OS Type select Operating System as Linux. Select Version as openSUSE and click on Next.
In Memory select the amount of base memory as 512 MB and click on Next. In Virtual Hard Disk the recommended size of the start-up disk is indicated as 8.00 GB. Select Create a New Hard Disk option and click on Next. In Create New Virtual Disk wizard select File Type as VDI (VirtualBox Disk Image), which is the default selection, and click on Next. In Virtual disk storage details select Storage details as Dynamically allocated. A dynamically allocated disk only uses space as it gets filled up based on requirement, which could slow down its use. A Fixed size disk take longer to create but is faster to use. Click on Next. Select Dynamically allocated and select Next. In Virtual disk file location and size specify Location as OpenSuse and Size as 8.00 GB. Click on Next. In Summary click on Create. An OpenSuse virtual machine gets created. Select the virtual machine and click on Start Oracle VM VirtualBox Manager.
In VirtualBox Information click on OK for the default settings. The First Run Wizard gets started when the virtual machine is started for the first time so that an OS may be installed. Click on Next. In Select installation Media select Media Source as the openSUSE KDE Live ISO. Click on Next.
In Summary click on Start. The openSUSE Installer gets started. Click on Installation when the installer starts.
In Welcome click on Next. In Clock and Timezone select the Timezone, time and date settings and click on Next. In VirtualBox Information click on OK. In Suggested Partitioning click on Edit Partitioning Setup. The Expert Partitioner shows the Avaliable Storage on Linux. Click on Accept.
Click on Next in Suggested Partitioning. In Create New User specify the username and password and click on Next. In Live Installation Settings click on Next. Click on Install. In Confirm Installation click on Install. The installation starts up. In Perform Installation the root filesystem and the live image are shown as being copied. The OpenSuse Kernel gets started. The OpenSUSE virtual machine is shown as running.
Linux login for root gets performed.
Next, we'll configure Ubuntu on Oracle VirtualBox. Create a new virtual machine as in the previous section. In VM Name and OS Type select Operating System as Linux and Version as Ubuntu. Click on Next. A virtual machine for Ubuntu gets created. Using the same procedure as in the previous section initialize the new virtual machine. Click on Start. Select Installation Media as the Ubuntu iso. Click on Next. The Linux ISO for Ubuntu gets started. Click on OK in VirtualBox Information. Ubuntu 11.10 virtual machine ISO gets initialized. Click on Install Ubuntu.
In Preparing to Install Ubuntu a system test is performed for enough drive space (4.4 GB) and connection with the Internet. Click on Continue. In Installation Type select Erase disk and install Ubuntu. The disk to be erased is not the Windows OS on which the Oracle VirtualBox is running, but the virtual machine disk. Click on Continue.
In Install>Erase Disk and Install Ubuntu the drive is selected by default. Click on Install Now.
Specify a username and password and click on Continue. Ubuntu gets installed on the virtual machine. Specify Password for the user. Ubuntu is shown as installed.
Next, we'll install Fedora on Oracle VirtualBox. Create a new virtual machine as in the previous sections. Select Operating System as Linux and Version as Fedora. Click on Next. A virtual machine for Fedora gets created. Click on Start to start and initialize the virtual machine. The First Run Wizard gets started. In Select Installation Media select the Fedora ISO. Click on Next. Fedora OS gets installed on the virtual machine.
In this article we learned how to install and configure Linux distributions openSUSE, Ubuntu, and Fedora on Oracle VirtualBox virtualizer. We used the ISOs for virtual machines to install the Linux distributions on virtual machines running on Oracle VirualBox.
The Internet of Things (IoT) is growing rapidly by extending current technologies, products and networks. By 2020, Cisco estimates there will be 50 billion connected devices. Gartner has forecast revenues of over $300 billion, just to IoT suppliers. Now is the time to figure out how you’ll make money – not just create innovative products. With hundreds of new products and companies jumping into the IoT fray every month, there’s no shortage of innovation. Despite this, McKinsey/VisionMobile data shows "less than 10 percent of IoT developers are making enough to support a reasonably sized team....

Just over a week ago I received a long and loud sustained applause for a presentation I delivered at this year’s Cloud Expo in Santa Clara. I was extremely pleased with the turnout and had some very good conversations with many of the attendees. Over the next few days I had many more meaningful conversations and was not only happy with the results but also learned a few new things. Here is everything I learned in those three days distilled into three short points.

The cloud. Like a comic book superhero, there seems to be no problem it can’t fix or cost it can’t slash. Yet making the transition is not always easy and production environments are still largely on premise. Taking some practical and sensible steps to reduce risk can also help provide a basis for a successful cloud transition. A plethora of surveys from the likes of IDG and Gartner show that more than 70 percent of enterprises have deployed at least one or more cloud application or workload. Yet a closer inspection at the data reveals less than half of these cloud projects involve production...

Too often with compelling new technologies market participants become overly enamored with that attractiveness of the technology and neglect underlying business drivers. This tendency, what some call the “newest shiny object syndrome” is understandable given that virtually all of us are heavily engaged in technology. But it is also mistaken. Without concrete business cases driving its deployment, IoT, like many other technologies before it, will fade into obscurity.

Microservices are a very exciting architectural approach that many organizations are looking to as a way to accelerate innovation. Microservices promise to allow teams to move away from monolithic "ball of mud" systems, but the reality is that, in the vast majority of organizations, different projects and technologies will continue to be developed at different speeds. How to handle the dependencies between these disparate systems with different iteration cycles? Consider the "canoncial problem" in this scenario: microservice A (releases daily) depends on a couple of additions to backend B (re...
