5 Signs You're Overpaying for Azure Virtual Desktop

Azure Virtual Desktop can be incredibly cost-effective — or incredibly expensive. The difference often comes down to how well optimised your deployment is.

Many organisations set up AVD, get it working, and never revisit the configuration. The result? They’re overpaying, sometimes significantly, without realising it.

Here are five signs that you might be spending more than necessary on AVD — and what to do about it.

Sign 1: Your Session Hosts Run 24/7

The symptom:

Your session hosts are always on. All of them. Every day. Weekends too.

Why it matters:

Unless you run a 24/7 operation with consistent global usage, you don’t need full capacity around the clock.

Consider a typical office environment:

• 8am-6pm: Active usage (10 hours)
• 6pm-8am: Minimal usage (14 hours)
• Weekends: Very low usage (48 hours)

That’s 62 hours per week of low/no usage versus 50 hours of active usage. Running full capacity 24/7 means paying for unused resources more than half the time.

The fix:

Implement scaling — either Azure native scaling plans or an intelligent solution like The Smart Scaler. Even basic time-based scaling can reduce costs by 30-40%.

Quick check: Look at your host pool in Azure Portal. Are VMs always running, or do they scale with demand?

Sign 2: Your Weekend Usage Equals Weekday Usage (But Shouldn’t)

The symptom:

You’re running the same capacity on Saturday as you do on Tuesday.

Why it matters:

For most organisations, weekend usage is dramatically lower than weekday usage. Some see near-zero activity.

If your scaling doesn’t differentiate between weekdays and weekends, you’re over-provisioned for at least 48 hours every week.

The math:

Weekday capacity: 50 hosts Weekend actual need: 5 hosts Overprovision: 45 hosts × 48 hours × 52 weeks = 112,320 wasted host-hours per year

At £0.10/hour, that’s £11,232 in unnecessary spend annually.

The fix:

Configure weekend-specific scaling rules. This is one of the quickest wins available:

• Scale to minimal capacity Friday evening
• Maintain skeleton capacity through the weekend
• Scale back up Monday morning

Quick check: Compare your Saturday usage metrics to Tuesday. If capacity is the same but sessions are 90% lower, you have a problem.

Sign 3: You’ve Never Adjusted for Holidays

The symptom:

Christmas Day comes and goes. Your AVD environment doesn’t notice.

Why it matters:

Public holidays typically mean zero (or near-zero) usage. But if your scaling isn’t holiday-aware, you’re running full weekday capacity for days when no one works.

UK organisations have 8 bank holidays. US organisations have 11 federal holidays. Add company closures (Christmas-New Year shutdown, anyone?) and you’re looking at 10-15 days per year of unnecessary capacity.

The math:

15 days × 50 hosts × 24 hours = 18,000 wasted host-hours per year

At £0.10/hour, that’s £1,800 in unnecessary spend — and that’s conservative.

The fix:

Implement holiday-aware scaling. Either:

• Manually adjust schedules before each holiday (tedious, error-prone)
• Use a tool with built-in holiday calendars (like The Smart Scaler)

Quick check: Look at your Azure cost data for the last major holiday. Did costs drop? If not, you’re overpaying.

Sign 4: Your Hosts Are Over-Specified

The symptom:

You’re running D-series VMs when B-series would suffice. Or you’ve got 32GB RAM hosts for users who only need 8GB.

Why it matters:

VM sizing directly impacts cost. A D4s_v5 (4 vCPU, 16GB RAM) costs roughly twice what a D2s_v5 (2 vCPU, 8GB RAM) costs.

Over-specifying is common, usually because:

• Initial sizing was based on worst-case estimates
• “Better safe than sorry” thinking prevailed
• Nobody has revisited the decision since deployment

But over-specification means overpayment — every hour of every day.

Signs you’re over-specified:

• Host CPU utilisation consistently below 30%
• Memory usage consistently below 50%
• Users not reporting performance issues on lower-spec hosts

The fix:

1. Monitor actual utilisation — Use Azure Monitor to track CPU, memory, and disk metrics
2. Identify over-provisioned hosts — Look for consistently underutilised VMs
3. Test smaller sizes — Try reducing spec on non-critical host pools
4. Right-size gradually — Don’t change everything at once

Quick check: What’s the average CPU utilisation across your session hosts? If it’s under 30%, you’re probably over-specified.

Sign 5: You Have No Visibility Into Actual Usage

The symptom:

You can’t answer basic questions like:

• What’s our peak concurrent user count?
• When does usage peak and trough?
• How many sessions do we average daily?
• Which host pools are underutilised?

Why it matters:

You can’t optimise what you can’t measure. Without visibility, you’re guessing at capacity requirements — and guesses tend toward over-provisioning.

Organisations without usage visibility typically:

• Over-provision by 30-50% “just in case”
• Can’t justify right-sizing decisions
• Miss opportunities for optimisation
• React to problems instead of preventing them

The fix:

Implement proper monitoring and analytics:

1. Enable Azure diagnostics — Basic telemetry for your AVD environment
2. Configure Log Analytics — Central repository for usage data
3. Build dashboards — Visualise patterns and trends
4. Review regularly — Monthly usage reviews to identify optimisation opportunities

Or use a tool like The Smart Scaler that provides visibility as part of the package.

Quick check: Can you pull up a graph of concurrent sessions over the past month? If not, you lack visibility.

The Cost of Inaction

Each of these signs represents ongoing unnecessary spending:

Issue	Typical Overspend
No scaling	30-40%
No weekend adjustment	10-15%
No holiday awareness	5-10%
Over-specified VMs	20-50%
No visibility	Hard to quantify

These compound. An organisation with all five issues might be overspending by 50%+ on their AVD deployment.

For a £100,000/year AVD deployment, that’s £50,000+ in unnecessary costs annually.

How to Get Started

If you recognised your organisation in any of these signs, here’s what to do:

Quick Wins (This Week)

1. Check your weekend scaling — Are hosts running when they shouldn’t?
2. Review upcoming holidays — Do you have a plan?
3. Look at VM utilisation — Any obviously over-provisioned hosts?

Medium-Term (This Month)

1. Enable monitoring — Get visibility into usage patterns
2. Implement basic scaling — Start with time-based rules
3. Right-size test pools — Experiment with smaller VM sizes

Strategic (This Quarter)

1. Deploy intelligent scaling — Move beyond basic time rules
2. Implement holiday automation — Remove manual holiday management
3. Establish regular reviews — Monthly usage and cost reviews
