The real challenges of Image Management

The real challenges of Image Management

Remember Ghost?

Imaging technologies date back to the nineties. Software called Ghost was used to create bit-by-bit copies of hard disk content from one computer to the next in a process called cloning. Cloning allowed for rapid enrolment of new computers in an organization. It worked beautifully and saved lots of time as long as source and target computers were identical.

“As long as source and target computers were identical”... There’s the catch! Having the exact same hardware everywhere in your organization is challenging, if not impossible. So, we ended up having at least one image per hardware type.

Note: Not taking different software configuration into account here.

Keeping up with changes in your VDI environment

Fast forward to 2016. Hardware virtualization has more or less solved the problem of identical hardware in the datacentre. Virtual machines are identical which paved the way for image based deployments systems.

In VDI, new virtual machines are created by cloning images one way or another. No matter whether you’re cloning your images in-memory, adding new layers of applications on the fly or even if you are streaming the operating system, it’s all image based.

OS deployment in VDI is no longer a problem! Or is it?

Actually, VDI is not about deploying virtual hardware to end users. It’s about providing a workspace, it’s about applications and it’s about delivering a great end user experience wherever they may be.

During the past 20 years we’ve seen a tremendous growth in the number of users, applications, and changes. Simply keeping track of your images and keeping up with their updates is becoming more and more challenging. And with the arrival of Windows as a Service (Windows 10), things are only going to accelerate. And with that, the challenges of managing images remain more or less the same.

So, what challenges are we talking about?

  • Simply keeping your images up-to-date with the latest Microsoft updates can be very time consuming.
  • Reliably rebuilding images in case of failure or as part of a disaster recovery is almost impossible.
  • Just-in-time configuration after the image was booted for the first time.
  • Supporting IT management tools like virus scanners and monitoring agents.
  • Detailed documentation of all configuration settings is outdated before the virtual ink is dry.
  • Adding, removing, updating applications or completely recomposing your images.
  • Sheer number of configuration, performance tuning and best practices settings to keep track of.
  • Windows policy settings that need to be ‘in’ the image.
  • What application is used in which image? And what applications does this image contain?

In another post, my colleague Sonny Puijk will take you through some of the things we do with our Image Management solution to take the sting out of regular image maintenance.

Finally, I’d like to reference this excellent article by Aaron Parker where he provides some insights into how often images are being updated and the pain that goes with it.

What our customers are saying

Bill Galloway - Pivot3

“The labs at Pivot3 have hundreds of machines. A portion of those are running different Login VSI configurations so we can be constantly configuring with different hardware to see how that affects desktops. Then we tweak the RAM and CPU, and tune so we know how many users we can support.”

Bill Galloway, Founder and CTO at Pivot3


Sajad Shah - Cancer Research

"Login VSI has empowered us to make more informed decisions on releasing a new vDisk which we now do on a monthly basis. We have found that Login VSI tests can also flag other issues in our environment that may not be picked up by our standard User Testing which allows us to either make the appropriate changes to the vDisk or workload script adjustments to run successful tests. This has given us peace of mind and allows us to release VDI’s with confidence."

Sajad Shah, Senior Technical Analyst at Cancer Research UK


Michael Cooper - Citrix

"We use Login VSI as a level set. If we are looking at a system that we are putting on brand new hardware or that we are putting in the cloud, we may see those environments completely differently but the end result is: is the user going to have a good solid happy user experience? And what Login VSI provides us on all three platforms is fairly consistent apples-to-apples comparison: is the user happy?"
