I am coming towards the end of a contract as IT Manager for a reasonably
affluent not-for-profit organisation, the British Small Animal
Veterinary Association. Part of my remit is to develop an IT strategy
for the next 3-5 years.
CURRENT SET-UP
The organisation runs 3 Windows 2000/2003 servers in-house providing:
- File and Print
- Financial system (Microsoft Great Plains)
- Bespoke VBA administrative system
- Terminal Services
- Mail (Microsoft Exchange)
- Firewall and Proxy (Microsoft ISA)
In addition there is a .NET based website hosted remotely that links
back to the admin system and Microsoft Great Plains.
We have 25 desktops all running Windows XP and a varying number of
volunteers accessing via Windows laptops.
CHANGE EVALUATION
I have been a Linux user for around 6 years and Ubuntu evangelist since
October 2004. I have now completed an evaluation which leads me to
believe the correct course of action for this organisation is migrate
all desktops and services to Ubuntu with commercial support from
Canonical. A phased approach is obviously required, summarised as:
[1] Desktop application migration to FOSS equivalents, retaining MS
Windows (OOo, Firefox, GiMP, etc.)
[2] Server migration to Ubuntu and FOSS applications for
- File and Print
- Firewall and Proxy
- Domain control
- Mail
Retention of a Windows server for financial and administrative systems
and Terminal Services
[3] Desktop migration to Ubuntu, with TSclient access to financial and
administrative systems
[4] Replacement of financial and administrative systems with
Linux-compatible FOSS (or possibly commercial) alternatives, and removal
of Terminal Services
HELP ME PLEASE!
Firstly, I would appreciate your advice on whether the above outline is,
generally speaking, a recommended course of action and in a general
sense whether there are alternatives worth considering. Secondly, and I
guess more importantly, I need to supplement the strategy with a
comprehensive set of convincing arguments for migrating over to Linux
(and where possible FOSS), and this is where I really need help.
Do you have material you could supply me with, or point me to resources
that have proved successful? If I write these myself they will just
sound biased and may well miss important points, so I'd rather access
established existing material. The material should try to achieve the
following:
- An overview of what the Linux-based (preferably FOSS) options are
- Reasons for considering Microsoft alternatives
- Benefits and risks of migrating over
- Guidelines on cost estimation - both eventual savings if any and costs
for getting there
- Support structures that can help the journey
- Advisable plans and timescales
In other words, something that evangelises and de-bunks myths without
evangelising (if you know what I mean)!!
Any help at all that you can give me in this area would be highly
appreciated.
Thanks
