Q: What’s your Windows template approach?

Q: What’s your Windows template approach?: "

Once upon a time, I was a Windows Server administrator. Most of my focus was on Windows Server deployment and management. VMware virtualization was a large interest but my Windows responsibilities dwarfed the amount of time I spent with VMware. One place where these roads intersect is Windows templates. Because a large part of my job was managing the Windows environment, I spent time maintaining “the perfect Windows template”. Following were the ingredients I incorporated:

VMware virtualization is now and has been my main focus going on two years. By title, I’m no longer a Windows Server administrator and I don’t care to spend a lot of time worrying about what’s in my templates. I don’t have to worry about keeping several applications up to date. In what I do now, it’s actually more important to consistently work with the most generic Windows template as possible. This is to ensure that projects I’m working with on the virtualization side of things aren’t garfed up by any of the 30+ changes made above. Issues would inevitably appear and each time I’d need to counter productively deal with the lists above as possible culprits. As such, I now take a minimalist approach to Windows templates as follows:

In large virtualized environments, templates may be found in various repositories due to network segmentation, firewalls, storage placement, etc. As beneficial as templates are, keeping them up to date can become a significant chore and the time spent doing so eats away at the time savings benefit which they provide. Deployment consistency is key in reducing support and incident costs but making sure templates in distributed locations are consistent is not only a chore, but it is of paramount importance. If this is the scenario you’re fighting, automated template and/or storage replication is needed. Another solution might be to get away from templates altogether and adopt a scripted installation which is another tried and true approach which provides automation and consistency, but without the hassle of maintaining templates. The hassle in this case isn’t eliminated completely. It’s shifted into other areas such as maintaining PXE boot services, maintaining PXE images, and maintaining post build/application installation scripts. I’ve seen large organizations go the scripted route in lieu of templates. One reason could simply be that scripted virtual builds are strategically consistent with the organization’s scripted physical builds. Another could be the burden of maintaining templates as I discussed earlier. Is this a hint that templates don’t scale in large distributed environments?


Do you use templates and if so, what is your approach in comparison to what I’ve written about?

Favigen, Favicon Generator

Favigen, Favicon Generator : " Favicons are small icons that help identify websites. They are used as a visual representation of a website both in the web browser and at many online services. The three most prominent locations of favicons are the browser’s address bar, the tabbar and the bookmarks folder. Many webmasters like to create custom favicons to add that custom identifier to their website. Favicons can be created in many image and icon editors, but also online. Favigen is a straightforward favicon generator that can turn an image into a favicon. All that it takes is to pick an image from the local hard drive first, select the dimensions of the favicon and click the submit button to make the service generate the favicon. Favigen supports several image formats, including jpg and png, and it does not seem to have size restrictions either. Available image dimensions range are 16×16, 32×32 and 64×64. The generated favicon is displayed directly on the page. A click on do...

A simple rsync script to back up your home directory

A simple rsync script to back up your home directory : " Backing up important data is obviously something we should all do. Unfortunately, it is not always easy to make it happen. We get lazy; we do not have the additional hardware for a backup server; it takes a long time and a lot of CDs to back up to optical media; we do not trust online backup services; backup schemes are difficult to set up and use — any of dozens of reasons can stand in our way. Still, we know we should be backing up our important data. Modern open source Unix-like operating systems offer a plethora of options for incredibly simple, effective backup schemes, however. If the problem is figuring out how to set one up, a simple rsync solution may be exactly what you need. The rsync utility is used to synchronize files between two systems. It does so by way of incremental copies, only copying from the source to the destination what has not already been copied there, saving time, network bandwidth, and syst...
