It’s time for K-12 schools to begin transitioning to “Cloud Computing and Desktop Virtualization”.
Cloud Computing and Desktop Virtualization have important educational and financial benefits. For the purposes of this post I am going to keep this very simple:
Whether educational tools and resources are located in the ‘Public Cloud’ or the ‘Private Virtualized Cloud’, they are accessible from anywhere, at anytime, via a web browser. This unlocks the resources of the school and makes them available 24x7x7. By doing so we extend learning opportunities and get more return on our software investment.
Schools utilizing this new paradigm are able to increase the number of computers available to students without increasing their budget because they can purchase less expensive devices. Because ‘Public Cloud’ and ‘Private Virtualized Cloud’ applications run on servers, the student device can be anything that can run a web browser, including a $300 Netbook, a $200 iTouch, or any Smartphone.
School IT support teams can be more productive because they are no longer maintaining dozens of educational applications on thousands of individual computer hard drives. The applications now reside on servers in the ‘Public Cloud’ or the ‘Private Cloud’. Since the software is on servers, software does not have to be ‘pushed out’ or ‘ghosted’ to every hard drive. The end-user’s computer accesses the servers and the new software and can use it immediately.
What first steps should I take?
Determine what applications and data you are comfortable having hosted in the Public Cloud, what applications will need to be hosted in your own Private Virtualized Cloud, and what applications will need to remain hosted on local hard drives. Remember that video and audio editing, computer programming, and some high end CAD applications may not be suited for the Public or Private Virtualized Cloud. Planning this hybrid environment is a great first step.
Make a commitment to subscribing to applications delivered from the Cloud. Begin researching alternatives to the software applications and resources that are currently loaded on your desktop hard drives. Whenever there are Web-based applications that are comparable to the hard drive-based applications, give precedence to the Web-based product even if it is not as feature rich and robust.
Begin planning the Private Virtualized Cloud by determining what desktop virtualization strategy you want to deploy:
The least expensive option called Client Virtualization allows for approximately (50) simultaneous users to share the server OS and whatever applications are being hosted.
Another option is called Virtual Desktop Infrastructure (VDI). In this approach the entire end-user machine (Desktop OS, Applications, and Storage) is virtualized on the server. Obviously, fewer VDI desktops (approximately 20-25) can be hosted and run simultaneously on each server. This requires the purchase of more servers and OS licenses than in the Client Virtualization approach.
Although these are the main approaches to virtualization there are other strategies. In reality, most schools will likely employ both Client Virtualization and VDI strategies in their Private Cloud. The planning process will help determine which users use which strategy.
One final piece of advice as you begin this journey, find some independent technical experience and advice. Be careful here since Dell, HP, IBM. Microsoft, and others have connections with specific virtualization companies and thus, their specific virtualization strategies.
Here is a very thorough and well thought out article by Brian Madden on the topic:
Don’t stand still. Don’t be paralyzed by the new terminology or the seeming complexity. The benefits of the Public Cloud and the Private Virtualized Cloud are too important.
It’s time to begin the process of transitioning to the new paradigm.
