OPINION: Life after Windows XP – FOSS and BYOD
- 27 November, 2013 09:30
In last week's instalment of this series, I looked at ways you can deploy and manage FOSS solutions at an organisational scale, including support for legacy Windows XP applications.
A great deal has changed since the heyday of XP - we now have to accommodate a broad range of other devices in addition to the desktop monoculture of yesteryear. Now, in addition to a FOSS ecosystem, you also have to contend with resurgent Apple laptops and i-Devices, an explosion of FOSS Android devices, the odd Windows 8/8.1 desktop or notebook, and you might even spot the occasional Windows 8 phone or RT tablet.
In this final instalment I look at coping with diversity in a FOSS environment.
Accommodating diversity with Samba
The bring your own device (BYOD) revolution suits FOSS-based ecosystems well and the Swiss army knife of inclusivity is called Samba (a play on SMB, Microsoft's proprietary "Server Message Block" protocol) - distributed with every Linux system.
The Samba project was started in 1991 by an energetic PhD student, Andrew Tridgell at Canberra's Australian National University, because he was annoyed with problems using his MS DOS PC to read files from a UNIX server in his lab.
Today Samba 4 can fool any MS Windows-powered computer into thinking it's talking to a bona fide Microsoft Server. Samba allows a Linux server to act as a domain controller, an Active Directory, network file and print server, name server, and other crucial "boiler room" network services.
It also takes advantage of Apple's capitulation to Microsoft's dominance, adding Windows network integration to their Macs to spur enterprise adoption - Samba suits them just as well. Naturally, Linux desktops and laptops integrate with Samba.
On the mobile side, support is similarly comprehensive, with Android users spoiled for a choice of no-cost apps, similarly iOS users, but details are sketchy for Windows Phone 8 users although I expect that they should also be able to connect.
As with a Windows Server, although you can set it up yourself, you may want to engage an IT professional to set up Samba and configure it for your requirements.
Your own cloud, sync and all
One of the key features of modern computing environments is the synchronisation of key data - your email, contacts, calendars, task lists, bookmarks, passwords - between devices. Many users entrust much of that personal info to Google or Firefox for transfer between desktop and smartphone or tablet.
For passwords, I prefer a specialised solution like Lastpass, which is compatible with all the FOSS technologies I use and stores all my web-related passwords in the cloud encrypted.
For storing and transferring files via the cloud, you can use well known proprietary cloud services like DropBox, or Ubuntu One, among others. These services provide an easy way to securely share and automatically synchronise files across all manner of devices.
In these post-Snowden days for many the cloud, particularly that large proportion of it residing in the US, has justifiably lost much of its appeal - a disturbing proportion of the big-name cloud services providers fail to live up to the IITP's very sensible Cloud Computing Code of Practice.
If you prefer to take charge of your own privacy, it's easy to make your own cloud - ownCloud offers many of the same capabilities as DropBox and Google's syncing services, but to and from your own server, either in your own office or on a leased server in a country without five eyes or a Patriot Act.
Geographically distributed organisations
Secure-by-design should be the mantra for any IT infrastructure, but that's especially important for distributed organisations. There's no need to skimp on security in the FOSS world - all the tools are at your fingertips.
Most FOSS desktops support a few industrial strength VPN clients and servers out-of-the-box. We have often used the FOSS OpenVPN with great success on Windows, Mac, and Linux desktops. It also works well with all your mobile devices.
You (or your FOSS tech) can use OpenVPN to turn your multiple LANs into a secure WAN, joined together via encrypted data "tunnels" across the Internet. OpenVPN also supports individual teleworkers who need to access organisational resources securely via any 'net connection.
FOSS is developed by the very communities that use, deploy and support it. Engineered by and with some of the biggest names in IT, the same value they build for their own use is available to anyone. It's industrial strength. Smart organisations can save license fees and gain competitive capabilities by adopting FOSS.
Migration to FOSS can be gradual, and needn't be all-or-nothing. With FOSS, you can embrace diversity, supporting a mix of FOSS desktops and devices alongside similar but proprietary solutions from Microsoft and Apple. The biggest advantage of migrating to Linux now is that you won't have to worry the next time locked-in customers next find themselves wringing their hands - you'll be busy just taking care of business.
