5 Server Virtualization Trends

Gartner Analyst Tom Bittman announced 5 virtualization trends to watch in 2012:

1) Competitive Choices Mature
2) Second Sourcing Grows
3) Pricing Models in Flux
4) Penetration and Saturation
5) Cloud Service Providers Are Placing Bets

What these mean is the market is maturing and businesses as well as cloud providers have more choices. More companies are working with Hyper-V than in the past and Open Source Vitualization is having more success in larger organizations as well as leading in the larger cloud providers such as Amazon and Rackspace. The cloud service providers are needing to make big bets as to if they want to invest more in the mainstream corporate virtualization providers VMWare and Microsoft or does it make more sense to stay with lower cost customized open source virtualization.

Larger corporations are looking to have options so they are not locked in with one virtualization provider and the proliferation and maturing of the virtualization market is adding price pressure as well as creating a changing pricing model.

Virtualization and the cloud are here to stay and will continue to penetrate and saturate. We are living in interesting times.

Understanding the Best Practices for Disk Imaging and Deployment

Guest Post:
by Matt Obrien, Dell Kace

Sitting through one installation after another is not themost cost-effective activity for the IT department, which is why many organizations are turning to other methods to install operating systems, drivers, and applications on new computers or when restoring an older device. These companies adopt a standardized software deployment system that captures the disk image as an image file where it can be edited, organized, and deployed to new or repurposed computers.

Basic Disk Imaging

A disk image is a file-by-file copy of a computer’s hard drive, which is saved in one or more image files. These files can be saved to a network, burned to a DVD, or sent to another storage device for further use. This image replicates the entire structure and contents of the hard disk, which can then be used to install operating systems on new computers and set up the necessary applications or to restore damaged systems.

This image lets the IT team set up every computer in a department or organization without having to install the individual components on every system. If the company has a large number of departments and devices, though, the number of images can start to get out of hand. In order to avoid some of the impending issues that can arise for this, many companies employ solutions for effective management.

Centralized Imaging

The images created in this process can be used as a baseline installation for a lot of the normal, everyday, technical needs of the company because they have the basic setup and all the associated patches, applications and programs ready to go. The IT team will still need a way to access all the information when necessary and deploy the right disk imaging to the right device.

By uploading everything to a centralized “image library” the team will be able to archive and manage all their images and easily deploy, edit and maintain them. Different departments may require completely different operating systems and applications, and this allows the IT team to provision everything (even to remote users) from a single, centralized console.

Scripted Installations

Installing and configuring all these systems can be very time consuming, and there are more cost-effective things the IT department could be doing. Scripted installs allow the IT team to install operating systems and applications and even configure the settings without having to sit in front of every computer and manually enter the necessary installation values.

When disk images are deployed from a centralized location, it is possible to use an answer file to respond to all the installation questions and completely automate the process. No one needs to sit in front of a computer for extended periods just to click “Yes” or “No” occasionally. The answer file provides the script for running these installations so the IT department can move on to other tasks while still deploying the necessary installations on each system.
