While deep thinking my “Not a VLE” Project I began doing a topology graph for schools information and data flow, part of this process lead me into looking at processes that local servers do to ensure teaching and learning is continuous.
When I say that Primary School ICT is complicated, some of you may be shocked by just how complex it is. An average school may have just 2 servers and 50 or so clients but the amount of processes involved to deliver the perfect desktop experience is huge.
A simplified diagram of an average Primary School’s ICT from a process point of view:
Recently we have found an upsurge in schools buying EEE’s with XP Home and we have considered leaving Home on and seeing how they get on:
Here are the initial negative reasons why XP Home without a domain controller(server) is not suitable for a school…
(A Pupil may also be a teacher)
The problems:
- No Account restrictions – Pupils can break their device.
- No Centrally manageable Anti-Virus – Pupils may get a virus and the school wouldn’t know about it.
- No Windows update monitoring – Pupils may not have the latest windows on their device so may be at risk.
- No Authentication to printers – Pupils would not be able to 1 click print as easily.
- No ability to deploy software – Software would not be able to be “pushed” from the server meaning each piece would have to be individually installed.
The Fixes:
- No Account restrictions – Keep an image ready to restore from DVD/USB HD, this is not a complicated process and should be done as part of best practice anyway. All locally saved documents are remotely backed up using either Syncplicity, humyo or remote backup from Primary Technology
- No Centrally manageable Anti-Virus – An organization level web managed antivirus web2 application
- No Windows update monitoring – Teach pupils to periodically check for the latest windows update
- No Authentication to printers – Stop printing, use email, blog, etc.
- No ability to deploy software – Use web2 applications – Legacy applications could be supported by Thinapp or an app publishing platform?
The advantages to the Fixes:
- No Account restrictions – Increased Data protection as pupil information only lies on the MIS server (Which could eventually be easily hosted)
- No Centrally manageable Anti-Virus – Much easier for technical support providers to manage large number of devices and for schools to check status.
- No Windows update monitoring – Children will know how to update their systems in the future.
- No Authentication to printers – Record is kept of what/when is sent and we don’t waste paper/ink
- No ability to deploy software – Web2 applications tend to be available anywhere and do not require updating.
The disadvantages to the Fixes:
- No Account restrictions – Time spent in restoring devices and loss of local copy of data will mean a restore process from remote backup.
- No Centrally manageable Anti-Virus – Increased internet bandwidth usage
- No Windows update monitoring – Large updates could take a long time.
- No Authentication to printers – Email, blog systems could be abused.
- No ability to deploy software – Web2 companies and/or their hosting providers can have issues leading to downtime and unavailability.
The other angle to approach this from is a web3 angle which would be a cloud OS however for true data protection a school should always keep their own copy of any document they have worked on.
So what happens when the school’s internet connection goes down? Admittedly local servers are almost as likely to go down, but still it just feels like a bad idea.
Yea, you are right. We have some stats @ PrimaryT that show servers are more likely to go down than the internet connectivity and with the majority of new development in edu happening on the web online is a far more sensible place to hedge your bets.
