the fact that you cost 10x the normal cost of a Windows admin.
And that has what to do with it? This is completely misleading. Apples to apples, UNIX people cost about 20% more than Windows people.

Now that said, perhaps they can fire 9 other Windows admins because they don't need them.
You are just making up numbers for effect. Real world, you need roughly half the UNIX admins and they cost about 20% more. So if you needed ten Windows admins, you need five UNIX at the pay rate of six of what you had before.
In snowflake shops, where UNIX has the least value, the common number is that you pay only 60% what you did in Windows administration.

Assuming you can cut down on staff by 20%, the cost of the Linux admins being 20% more makes it a wash - and I believe you've already stated that you think your savings should be a lot more than a 20% staff reduction in a large organization.
Just so we are on the same page, I am and have been agreeing with you for the last few posts.

But even big Windows shops don't have one admin for every 10 Windows machines, it's probably closer to 50 or 100, or more. But you're right in that you can have many many times that number of servers per admin for Linux.
Actually that's not generally true. Only super high end Windows shops ever get above 30 per admin. More typically, even on Wall St. in a good shop I have seen around 35 per admin (and those admins are pushing $180K so don't start saying that the UNIX people are insanely expensive at $200K) and bad ones are around 5-10.
Same shop with 35 per Windows had 300 per UNIX. That's anecdotal, but a real world, 20% price difference in pay number shop.
In the low end shop on Wall St. it was more like 10 per Windows and 150 per UNIX.

Right, so the 50% savings makes it a massive win.
-
And once you move to DevOps models, which nearly everyone does these days, the cost savings increases so much more as UNIX is so easier to scale up in that way that you don't even have the concept of servers per admin anymore.
-
And then going to cloud, the server density concepts make UNIX even that much more beneficial.
-
I saw that - I didn't think I was ignoring anything.
I don't recall the past (yeah well over a year ago) discussions saying that your staff reduction would be 50% compared to the 20% increase in individual staff added cost.
Which, you're right, is a huge win.

I had misread the original post you had made, it was worded oddly.

50% is kind of the assumption. I don't know of any shop first hand that was not way better than that, but assuming I'm only seeing really good UNIX shops. In the real world I tend to see closer to 80% reduction, but I don't think you will see that in shops converting from one to the other. You need to change a lot of underlying assumptions before you can hit those kinds of numbers.

I gotta ask - what makes managing those Windows boxes so much more time consuming? At that pay rate, those guys are should definitely be doing things as automatedly (made up word?) as possible, using scripts, etc.
Assuming the UNIX boxes all do the same thing, sure you can stack more boxes on one person, but if they are all unique, what is the support per admin numbers look like? Closer to Windows at 35?
-
UNIX also allows you to change hardware. It's not just about getting better density on the same boxes, it lets you move to different architectures (ARM, POWER, Sparc, Itanium) which let you go to faster machines, bigger hardware, mainframes, etc. which can result in even more cost savings at scale. At the very least, it offers more options.

That's why I use the term snowflake. The 50% - 80% reduction in staff is done in a snowflake environment where every box is unique. In the DevOps world, where we assume they are not unique, that's where you get the 1,000% or more reduction.
-
That is bending my mind that you can get 50-80% reduction in a snowflake environment.

Automating Windows is still considered, a specialist task. At $100K you have UNIX admins who automate with nearly every key stroke. At the same price, Windows admins do so rarely. UNIX is designed top to bottom around automation and everything in the culture is based around it. Windows is making incredible strides in this area but is nowhere near there yet - more because of the culture than because of the tooling. But the tooling is very new still.
But how many Windows shops can, with zero effort, poll every server that they have, instantly, and get a report on uptime, for example? This is simply a "command" in UNIX. No planning needed, no setup, no special tools. It just works.
In Windows you have to plan to automate, in UNIX it often "just happens."

I'd be surprised today if that particular request wasn't just a command today on Windows too ( a powershell command), but you're right it's definitely a culture thing.

It might be. But every UNIX admin, even juniors, know how to do that. In Windows, outside of Rob and Martin who teach PowerShell, find me anyone who can do it without looking it up and even then, maybe it is challenging.

I'll definitely give you that.

And UNIX can do it without an infrastructure like AD if you don't want one. Windows "can" too but you give up a lot to do it.

Does that assume that all of the UNIX boxes have the same username and password setup on every box?
