Maintenance as the driver for system choices
Thanks all.
The theme I see running through these comments is an important one: that maintenance of medium sized private networks is challenging and that attempts to limit the complexity by adopting a single manufacturer's software platform are only partly successful.
First, the idea that maintenance is difficult and expensive in medium-sized networks. Few purchasers or users are aware of the effort required to keep private nets working and even fewer fully factor these costs into their procurement. Are medium-sized networks more vulnerable to maintenance problems? I suspect so. Small nets have good performance characteristics because they are small and (mostly) local and because COTS works well here. Big-iron networks are lifeblood for their owners and so get critical planning and maintenance assets as a matter of course.
Medium-sized nets usually result of growth-by-accretion over years and thus have legacy and modern components and a wide variety of uses and users. They tend to be cost centers for their organizations and so get minimal support until something goes wrong -- usually hitting the response-time ceiling or a security breach. But even these events don't shake out enough resource to address the problem; the 'solution' is nearly always incremental and add-on.
Second, the underlying problem will never be resolved. Instead, technological change will simply make it unimportant. In my own case, it is clear that the university is not capable of actually managing the technology it uses. Nor should it be. The idea that every institution -- even one that claims to be technology oriented -- should own and manage its own networks and platforms is simply not on. The existence of IT shops in hospitals, universities, and most businesses is an anachronism -- they are the cottage industries of the 21st century and can be expected to simply disappear over the next decade. Even the most cursory examination of the costs of maintaining a bespoke IT shop will show that, except where deep security is required, it never pays to do so. We already outsource virtually every aspect of operations at every level and web 2 is making that even easier.
