How to install Windows 10 in a virtual machine ?

After last week’s Windows 10 briefing, a brand new build of the Windows 10 Technical Preview was released publicly. Anyone can sign-up for the Windows Insider program and get a taste of Windows 10. Of course, pre-release builds should never be used as a primary OS, so today I’ll walk you through how to run the Windows 10 Technical Preview in a virtual machine.

Under normal circumstances I would do this walkthrough with Oracle’s VirtualBox. It’s free, open source, and works on just about any operating system. Sadly, the drivers appear to be broken for the time being. I couldn’t get sound or networking to work at all, and the screen resolution is severely limited. A quick peek at the community forums shows that other people are having the exact same problems, so hold off using VirtualBox for Windows 10 until these major kinks get worked out.

Instead, I’ll be using the free VMware Player application. It works like a charm, but it’s only available for Windows and Linux. VMware does offer premium virtualization solutions for OS X, but that’s a large investment just to test a preview build of Windows. I can’t recommend dropping $70 if this is all you’ll be using it for. With all that in mind, let’s jump in.

1. Download the Windows 10 ISO

First off, head over to the Windows Insider site, and sign up. Once you’ve agree to the terms of service, proceed to the download page, and pick which disc image you want to download. For the purposes of this walkthrough, I’m using the 32-bit English ISO, but go with whatever works for your set-up.

2. Create a new virtual machine

Now, you need to install VMware Player. Head to the download page, pick which platform you want, and complete the installation.

Once the application is installed, launch it, and navigate to Player > File > New Virtual Machine to get this party started.

3. Find your Windows 10 ISO

Next, you need to tell VMware Player where to find the Windows 10 ISO. Select the second option labeled “Installer disc image file (ISO),” and then navigate to the Windows 10 ISO you downloaded earlier.

4. Choose your save location

Pick out a name for this virtual machine, and then select where you’d like it to be saved.

5. Configure your virtual hard disk

On this screen, you need to choose how big you want your virtual disk to be. 60GB is the default, but you can increase it as needed. Just make sure you have enough free space on your actual hard disk.

By default, VMware Player will split your virtual disk over multiple files, and I recommend leaving it that way. Unless you have a specific reason to change it, keep it as is.

6. Customize your hardware configuration

Next, click the “Customize Hardware” button before we finish the initial set-up.

7. Allocate RAM

The default here is 1GB, but more would be better. I have 16GB of RAM in my machine, so I decided 4GB was an appropriate allocation for this virtual machine. Follow the guide on the right of the screen, and don’t go above the maximum recommended memory. If you outstrip what’s available, you’ll end up paging to the hard disk, and making everything slow to a crawl.

8. Configure the CPU

Switch over to the CPU tab, and choose how many cores you want to dedicate to this machine. One is the default, and that’s probably a safe starting point. My machine has four cores, so I usually end up bumping it to two cores for virtual machines, but your milage may vary.

Now, take a look at the button labeled “Virtualize Intel VT-x/EPT or AMD-V/RVI.” If you’re using the 64-bit version of Windows 10, this is mandatory. Of course, your CPU needs to support this functionality, so use this tool from Microsoft to verify that it will work with your processor.

9. Begin the installation

Close out of the hardware configuration, and “Finish” the initial set-up. Now, boot up your virtual machine, and install Windows 10 just like you would normally.

10. Install the VMware tools

Once Windows 10 has finally booted up, navigate to Player > Manage > Install VMware Tools. It will mount a virtual DVD, and pop up a notification in the bottom right. Navigate to the disc in Windows Explorer, launch the appropriate executable, and follow the on-screen instructions.

Note: If you don’t already have the VMware tools on your PC, follow this process to download them.

11. Reboot your virtual machine

When it’s finished installing, reboot your virtual machine.

1212

And you’ve virtualized Windows 10!

Finally, your Windows 10 installation is ready to use — even in fullscreen mode. Poke around, download the OS updates, and enjoy the cutting edge of Windows. And when something inevitably breaks, it won’t matter. This is just a virtual machine, so toss it, and start over.

How is the Cloud Computing different from primitive Client-Server Architecture?

cloud computing vs traditional client server

The primitive Client-Server architecture is a one-to-one communication between only two physical machines namely Client machine and Server machine (datacenter). Whereas the cloud computing, infrastructure is similar at the client side but varies at server-side. The server-side contains a main Cloud Controller that forwards the request to its worker machines known as Nodes. These nodes are a grid computing machines that dedicate all its resources to process application. These nodes are maintained in clusters. So a cloud computing infrastructure is quite complicated on server side that processes all the requests from clients and send the result back.

What is the difference between traditional datacenters and cloud?

Cloud computing uses the concept of datacenter as it is the datacenter is based on the tradition one so the difference between them are as follows:

• Cost of the traditional datacenter is higher, due to heating issues and other hardware/software related issues but this is not the case with the cloud computing infrastructure.
• It gets scaled when the demand increases. Most of the cost is being spent on the maintenance being performed on the datacenters, whereas cloud platform requires minimum maintenance and not very expert hand to handle them.

What essential things to know before going for cloud computing platform?

A user should know some parameters by which he can go for the cloud computing services. The parameters are as follows:
1. User should know the data integrity in cloud computing: It is a measure to ensure integrity like the data is accurate, complete and reasonable.
2. Compliance: user should make sure that proper rules and regulations are followed while implementing the structure.
3. Loss of data: user should know about the provisions that are provided in case of loss of data so that backup and recovery can be possible.
4. Business continuity plans: user should think about does the cloud services provide him uninterrupted data resources.
5. Uptime: user should know about the uptime the cloud computing platform provides and how helpful it is for the business.
6. Data storage costs: user should find out about the cost which you have to pay before you go for cloud computing.

What do you understand by CaaS?

CaaS is a terminology given in telecom industry as Communication as a Service. The Voice-over-Ip (VoIP) follows a same delivery model. CaaS can offer the enterprise user features such as desktop call control, presence, unified messaging, and desktop faxing. In addition to the enterprise features, CaaS also has a set of services for contact center automation that includes IVR, ACD, call recording, multimedia routing (e-mail and text chat), and screen pop integration.

What does software as a service provide in Cloud Computing?

Software as Service is another layer of cloud computing, which provides cloud applications like google is doing, it is providing google docs for the user to save their documents on the cloud and create as well. It provides the applications to be created on fly without adding or installing any extra software component. It provides built in software to create wide varieties of applications and documents and share it with other people online.

How important is platform as a service in Cloud Computing?

Platform as a Service is an important layer in cloud architecture. It is built on the infrastructure model, which provides resources like computers, storage and network. This layer includes organizing and operate the resources provided by the below layer. It is also responsible to provide complete virtualization of the infrastructure layer to make it look like a single server and keep it hidden from the outside world.

What are the different layers of cloud computing?

Cloud computing consists of 3 layers in the hierarchy and these are as follows:

1. Infrastructure as a Service (IaaS) provides cloud infrastructure in terms of hardware like memory, processor speed etc.
2. Platform as a Service (PaaS) provides cloud application platform for the developers.
3. Software as a Service (SaaS) provides cloud applications which are used by the user directly without installing anything on the system. The application remains on the cloud and it can be saved and edited in there only.
