For the past few years I've been contracting to a couple of schools and other people and as part of that, combined with a desire to automate as many repetitive tasks as I can, I have built up my own multi-site network management system.
Thing is, I'm not so sure if I want to keep doing this on my own. I enjoy most of the work, it's just the administrative side of running your own business and the "lower-end" tech support that I'm not so keen on anymore.
So I was wondering what advice other Geekzoners have with what I've got and what I should do with it, or if there's anyone interested in using it?
Below I explain what the system does and where it's at, and why I'm looking for a bit of a change. I'd like to hear your advice on what I should do from here.
In a nutshell, it's a multi-client managed network environment that for each site consists of one or more Linux/Samba servers (was openSUSE, moving to CentOS) and Windows workstations, using a combination of per-site and multiple-site management.
If there's more than one server on a site then services are usually clustered using a combination of NFS, DRBD, rsync and Unison and my own self-written "glue" scripts that allow me to load-balance and auto-failover service by service that I call "Sirius". Services can be individual services like Samba or qmail, or can be whole VMs (such as a Windows server or Zimbra VM).
Servers are built using a semi-automated set of build scripts I wrote that cut setup time by about two thirds and have server setups across different sites consistent, and help with syncing data from server to server whether clustering or upgrading (or both - upgrading a cluster).
Workstations are built and managed using a combination of open-source tools but mainly through a management program I again wrote myself ("Streamline") that does everything from automated application distribution/provisioning and maintenance to smart document synchronisation (again written muself) and redirection (user or machine based - so you don't fill a shared workstation HDD with a hunderd different people's MyDocs folders but still synchronise it with their individual laptops) to location-based printer management - some things absent when using Windows in a non-AD environment like Samba. Streamline also manages software updates including Windows, Office, Adobe Flash/Reader and so on.
This combines with an open-source imaging platform (FOG) to allow me to completely remotely rebuild a PC and provision the correct software for it, remotely, with a single click. If I rebuild a machine, often the user doesn't even know it's been done.
Basically I wrote it and added features to it to respond to the needs of the schools it's at as well as minimizing repetition between those schools and other sites, with a view to expansion.
It's designed so I can maintain per-site repositories for software as well as have a multi-site repository which I distribute software and updates multiple/all sites need like security updates and useful gratis software - again this is to minimize repetitive management. I can test then distribute a new or updated piece of software (or things like service packs) to multiple or all client sites in one go. The on-site servers synchronise relevant parts of the multi-site repository overnight and it's applied to workstations as they're used.
Licensed software such as Microsoft Office can be distributed using the site local repository but updates and service packs distributed multi-site.
It's designed to be green - queued-up maintenance tasks are performed when the user logs off and the machines are then powered down - they're not left on overnight. Full rebuilds are initiated with a Wake-on-LAN wakeup and a PXE boot.
Currently, this system is deployed in full at one Auckland primary school that I manage myself, in part (staged rollout this year) at one Auckland secondary school with its own network admin, and scaled-down "miniservers" are installed in three test sites to see how small a home/office I could economically scale the system down to. I figured from that test I can have a system that will provide full network management for a site as small as three or four workstations. To that end, it also supports management, document sync, and partial profile sync with Home Editions of Windows although I'd still class this somewhat experimental. I have two small sites doing this.
It's a little incomplete - the administrator-facing management tools are written in MS Access/VB for example which is not quite ideal but it works.
Overall I believe it works well at these sites - users seem happy and the automated build processes and server clustering mean any faults are repaired or at least worked around quickly - but I got these sites by word of mouth. I'm not a marketer and also I'm not too keen on continuing as a one-man band.
I'd like to combine this system with some sort of network management company so I can focus on continuing to develop/maintain it without having to worry about all the other bits that go with doing it alone from basic client tech support to GST returns.
It's survived the test of working well at a school - a difficult environment - so I'm confident it should be pretty solid in an office environment.
So now that I have this system, what should I do with it?
Any advice much appreciated.
