How much of your current career is spent preparing for things that will never happen, and why does that feel like a confession of failure when a consultant asks you to justify it?
It is an uncomfortable reality in the IT world that our greatest successes are often invisible. When the system stays up, when the remote users log in without a hiccup, and when the data flows like water, no one cheers. Reliability is the absence of a story. But the moment you try to quantify that reliability on a balance sheet, it begins to look like “waste.”
This is the trap of the modern efficiency audit-a process designed to trim the fat that frequently ends up nicking the carotid artery because it doesn’t know the difference between a redundant system and a useless one.
The Resource Optimization Analysis
The report sat on the corner of the desk, bound in a clean plastic spine that seemed to mock the chaos of the server room. It was a “Resource Optimization Analysis,” and it had identified a glaring “inefficiency” in the way the Remote Desktop Services environment was structured.
Specifically, it flagged the secondary licensing server-a machine mirrored with a duplicate set of Client Access Licenses-as an “unnecessary recurring cost.” The auditor, a person whose primary relationship with technology was likely a series of well-formatted spreadsheets, had circled the licensing spend in a vibrant, aggressive red.
To them, having two sets of CALs for a workforce that only occupied one set of seats at a time was like buying two tickets for the same movie “just in case” the first seat was uncomfortable. But the admin looking at that report didn’t see a duplicate expense. He saw .

: Catastrophic Failure
Primary Domain Controller goes offline. 85 remote employees at risk.
🛡️
9:14 AM (Instant): Failover Active
Secondary server takes the load. No re-authentication required. Users notice nothing.
The “wasteful” secondary server saved approximately $14,000 per hour in lost labor.
On that Tuesday, the primary domain controller had suffered a catastrophic hardware failure at . In a lean environment, that would have been the end of the fiscal year’s productivity. Eighty-five remote employees would have been kicked off their sessions, unable to re-authenticate, while the IT team scrambled to provision new licenses or recover a corrupted database.
Instead, because of that “wasteful” redundancy, the system failed over. The secondary server, already populated with the necessary licenses, took the load. The users didn’t even notice. The “waste” had saved the company roughly $14,000 an hour in lost labor.
The Maintenance Diver’s Logic
Omar D., a man who spends his days as an aquarium maintenance diver, understands this better than most corporate analysts. Omar doesn’t sit in front of a monitor; he sits inside 10,000-gallon saltwater tanks, scrubbing algae off the glass while sharks circle with a kind of bored curiosity.
He once explained to me that the most expensive part of a high-end exhibit isn’t the exotic livestock or the custom-molded coral. It’s the second life-support pump.
“The second pump just sits there. It draws no power, it moves no water, and it looks like a $12,000 mistake on a budget report. But if I pull that pump to make the board of directors happy, I’m not being efficient. I’m just the guy who turns a reef into a graveyard the next time a breaker trips.”
– Omar D., Maintenance Diver
This is the fundamental disconnect. We have reached a point in IT management where “lean” has become a synonym for “fragile.” We are so obsessed with removing the “slack” from our systems that we forget slack is what allows a rope to absorb a shock without snapping.
When you find a $20 bill in the pocket of a pair of jeans you haven’t worn since last winter, you don’t think, “I was being financially inefficient by leaving this capital uninvested for .” You think, “Thank God, I have twenty bucks.” It’s a moment of unearned grace.
Having a redundant licensing setup is that $20 bill, except the stakes involve the ability of an entire department to keep their lights on.
The Pedantry of the CAL Store
The logic of the audit is simple: If you have 100 users, you need 100 licenses. If you have 200 licenses, you are 50% inefficient. This logic, however, fails to account for the “licensing lock-out” that occurs when a primary server vanishes from the network.
Microsoft’s Remote Desktop Services are remarkably robust, but they are also pedantic. If the CALs aren’t reachable, the users aren’t working. It doesn’t matter if you “own” them in a legal sense; if they aren’t active on a live server that the client can talk to, they might as well not exist.
Many businesses try to avoid this by buying the bare minimum and hoping for the best. They treat their infrastructure like a game of Jenga, removing pieces until the whole thing starts to wobble, then calling that “maximum efficiency.”
But when you are dealing with the RDS CAL Store, you aren’t just buying digital permissions; you are buying the right to remain operational during the worst-case scenario.
Case Study: The “Glowing” Audit
I remember a specific instance where a mid-sized law firm was told by a junior consultant that they were over-licensed by nearly 40%. The firm had been through a merger and had kept the old server licenses active as a fallback.
The consultant’s report was glowing: “Eliminate these 50 User CALs and save $X per year.” They did it. They felt smart. They felt “optimized.”
later, their primary server was hit by a localized power surge that bypassed the UPS. Because they had deleted the “redundant” setup, they had no secondary server to point the remote workers toward.
They spent the next in a procurement nightmare, trying to get new licenses issued and installed while their billable hours evaporated. The “savings” from the audit were consumed in the first four hours of the crash. The rest of the outage was pure, unadulterated loss.
The Movement of Empty Space
There is a definition of redundancy that needs to be reclaimed. In linguistics, redundancy is what allows you to understand a garbled sentence. In engineering, redundancy is the extra bolt that holds the bridge together when the first one shears off due to thermal expansion.
We must test the edge case of efficiency. If a system is 100% efficient, it means it has zero capacity to handle change. A highway that is 100% efficient is a parking lot; every square inch of asphalt is covered by a car, but nothing is moving.
To have movement, you need empty space. You need “waste.” You need a gap between the cars so they can accelerate. Redundant licensing is that gap. It is the empty asphalt that allows the traffic of your business to keep flowing when there is an accident in the left lane.
100% Efficient Highway (The Parking Lot)
50% “Inefficient” Highway (The Flowing Traffic)
The auditor sees the cost of the spare; the administrator sees the cost of the failure. These two people are looking at the same server but living in different universes. One universe is governed by the quarterly earnings report, where “unused” is a sin. The other universe is governed by the laws of entropy, where everything that can break eventually will.
We have to be willing to defend the “waste.” We have to be willing to look a stakeholder in the eye and say, “Yes, we are paying for licenses that aren’t being used today, because my job isn’t just to manage today. My job is to ensure that tomorrow happens, regardless of what the hardware thinks about it.”
In the end, the efficiency audit that flagged your backup server didn’t fail because it was wrong about the numbers. It failed because it was wrong about the mission.
So, the next time you see a recommendation to trim your “duplicate” licensing, remember the $20 in the old jeans. Remember Omar D. and his silent, “wasteful” pump. And remember that the most expensive piece of software in the world is the one you didn’t buy when you had the chance, sitting in front of a screen that won’t let you in.
The drive for perfection in infrastructure often leads to a state where there is no room for the unexpected, which is, in itself, the greatest inefficiency of all.
We must embrace the “spare” not as an ornament of excess, but as the foundational stone of our continuity. Because when the audit is over and the consultants have gone home, you are the one left standing in the dark, and at that moment, a “redundant” license feels a lot more like a miracle than a mistake.
