I think both a) because it's already possible license free with Linux, people just don't have the incentive to learn howto. b) because the costs of cloud computing are in free fall. Look at the Google Compute Engine costs compared to a few years ago - but people are only now talking about (Azure?) because MS are trying so hard to copy Google. We *are* running print services in the cloud and as I've been pointing out it isn't nearly as heavy on bandwidth as people believe. WRT impero: Things like screenshot and streaming desktop data is absolutely minimal - I was running Citrix full desktops on dialup connections on early pentium 15yrs ago The thing your really don't want in the cloud is a caching proxy server! So yes I agree, but not for the points that you made.

rough breakdown is: 1200 Chromebooks Probably 350 BYOD (OSX/Chromebook/Windows Mix) 700 phones (guess) 200 Thin clients 80 Macs 270 Windows clients (WSUS!) roughly 2000 devices

sure but this shouldn't be part and parcel of student work. If it's going to a professional printer, share the link to them and use their bandwidth! Anyhow - it seems it's our sixth form windows BYOD that use our bandwidth: Top domains (24 hours) tlu.dl.delivery.mp.microsoft.com 14.1 (GBytes) au.v4.download.windowsupdate.com 6.3 (GBytes) Google 3.5 (GBytes) s3.amazonaws.com 2 (GBytes) iosapps.itunes.apple.com 1.5 (GBytes) umgstore.edgesuite.net 1.5 (GBytes) as-hds-uk-live.edgesuite.net 1.5 (GBytes) aupl.v4.b1.download.windowsupdate.com 1.4 (GBytes) hls-aka.vevo.com 1 (GBytes) upload.wikimedia.org 1 (GBytes) kind of ironic since we use GAFE exclusively.

we used to see this with publisher in the olden days.

what was it made in ?

You are not transmitting from a workstation to the internet - the work is already on the internet. I agree that it is downloaded if it is printed, but it's usually in a compressed format. All of our printers work on Google cloud print and it's barely affected bandwidth I don't think it would make the slightest difference if the servers were hosted on site or in GCE. Here bandwidth is more affected by windows update and youtube - printing barely registers.

This won't be the case in a few yrs.

Same here as ^. Teachers whitelist the video for students as appropriate.

The problem with Broadway is it is really limited to GTK+ apps which are few and far between. I can get it working with gedit etc but not inkscape. There's always X11 over ssh but then that is limited in browser support - don't think chrome ssh clients support it.

We provide many of these using Citrix, but it isn't so cost effective when you take into account the Citrix licenses and per user/device TS licenses. I've toyed with the idea of providing this type of service using something like guacamole on the frontend to some scalable, cloud based linux servers on the back. At the end of the day how much would someone be prepared to pay for an hours class-session of inkscape ? It would probably only cost a few cents to run it on AWS/GCE for that long but how would you charge for it? Schools wouldn't want to pay by the minute which leaves the per user model; this has to be expensive incase it's left running 24/7/

Nothing working at all on my linux desktop or any of the Chromebooks we have. This is exactly the sort of omishambles that drives people away from MS. We shouldn't need partially working plugins 5yrs ago let alone in 2016.

You need to pay Microsoft to learn about their licensing. Genius.

We have a samba server. A while back we had a script that compresses on upload, but it overloaded too much if many people uploaded simultaneously. Now I just run a one liner every now and again and insist it all gets uploaded to Google drive. find /dir/ -iname "*.mov" -o -iname "*.mpg" -exec ffmpeg -threads 8 -i {} -c:v libvpx-vp9 -b:v 100k -c:a libvorbis -vf "transpose=1" {}.webm

sounds right to me. On some cabs you might get away with 1u injectors which will fit in a smaller cabinet

This is called Security Through Obscurity

I can open a docx file, edit it and save it without converting to Google Drive or even downloading it with the Google drive plugins so I'm not sure where you got that idea from? In any case if you open in Word it would save a non-encrypted temp file somewhere.

I would advocate retiring them completely and using something like Google Drive instead. The advantages are all the data is encrypted in transit and at rest, it's unlimited storage, works on any device, doesn't require any extra software, can't be lost and is completely free.

I'm not really sure. Say I put a SIMS server on AWS/GCE/Azure I guess I wouldn't want that in the same local network as a web server if vpn connects to local clients. It's just a bit difficult to conceptualise I think. Another DMZ probably is the way forward. Just never done this before.

Wizzkids also has some fine integration tools for SIMS and classroom, calendars etc. Mere tid til bedre undervisning - Wizkids

Thanks but i realise my question didn't make sense so I edited the first post

Does anyone have any advise about network architecture for cloud based systems? If I was to put an internet facing computer on the school network it would typically go into a DMZ. When I create machines in an off-site cloud. I also create a VPN into the local school network. Should I also create a DMZ network in the offsite cloud ?

@mthomas08 I found that the main problem with BYOD was the windows updates. A caching windows update server might be a good thing to investigate, and restricting bandwidth to MS et al.
