· 7 min read

Summary​

  • Total Claims Checked: 35+ statistics and sources
  • Verified: 25 claims
  • Needs Correction: 4 claims (HIGH PRIORITY)
  • Cannot Verify: 3 claims (need additional sources)
  • Status: NEEDS FIXES (4 high-priority corrections required)

HIGH PRIORITY CORRECTIONS REQUIRED​

1. ❌ "88% cite rising costs as major challenge" (Line 55, 72, 96)​

Current claim: "88% cite rising costs as major challenge" Source cited: Spectro Cloud 2024 Actual finding: Spectro Cloud article states "nearly two-thirds of businesses say their Kubernetes TCO has grown" (which is ~66%, not 88%)

CORRECTION REQUIRED:

  • Option A (Recommended): Change to "Nearly two-thirds (66%) report Kubernetes TCO grew year-over-year" and cite Spectro Cloud 2024
  • Option B: Find the Spectro Cloud 2025 report which mentions "88% reported year-on-year rise in TCO" and update source citation

Source: https://www.spectrocloud.com/blog/ten-essential-insights-into-the-state-of-kubernetes-in-the-enterprise-in-2024

2. ❌ "42% name cost as their number one pain point" (Line 55, 73)​

Current claim: "42% name cost as top issue" Source cited: CNCF FinOps Survey Actual finding: The 42% statistic does NOT appear in the CNCF FinOps microsurvey (March 2024)

VERIFIED from different source: Spectro Cloud's 2025 State of Production Kubernetes report states "cost overtook skills and security as the #1 challenge at 42%"

CORRECTION REQUIRED:

  • Change source citation from "CNCF FinOps Survey" to "Spectro Cloud 2025" in statistics table (line 73)
  • Update text references to cite Spectro Cloud 2025, not CNCF FinOps

Verified source: Multiple articles reporting on Spectro Cloud 2025 report

3. ⚠️ "40% lack skills or headcount to manage" (Line 56, 77)​

Current claim: "40% lack skills or headcount" Source cited: Spectro Cloud 2024 Actual finding: The Spectro Cloud article mentions "difficulties accessing the right talent and skills" as an inhibitor but provides NO specific percentage

CORRECTION REQUIRED:

  • Remove "40%" statistic OR find different source that supports this specific number
  • Consider rewording to: "Teams cite difficulties accessing talent and skills" (without percentage)

4. ⚠️ 37signals Case Study Source Attribution (Lines 187-198)​

Current issue: Blog cites https://dev.37signals.com/our-cloud-spend-in-2022/ for ALL 37signals numbers Actual finding: That blog ONLY contains the $3.2M 2022 AWS spend figure. All other numbers (Dell servers, Pure Storage, savings projections) come from later reporting by The Register, IT Pro, and other tech news outlets tracking their multi-year migration.

VERIFIED numbers from alternative sources:

  • ✅ $3.2M 2022 AWS spend (from original 37signals blog)
  • ✅ $700K Dell servers (The Register, IT Pro reporting)
  • ✅ $1.5M Pure Storage for 18 PB (The Register, IT Pro reporting)
  • ✅ $10M+ five-year projected savings (IT Pro, System Administration reporting)
  • ✅ Compute savings details (various tech news reporting)

CORRECTION REQUIRED:

CANNOT VERIFY (Additional sources needed)​

1. ⚠️ "75% use Helm (up from 56% in 2023)" (Line 59, 83, 137)​

Source cited: CNCF Benchmark 2024 Issue: The CNCF blog post summary does NOT contain these Helm adoption percentages. The post discusses outdated Helm charts (70% of orgs have 11%+ workloads on outdated charts), not overall adoption rates.

Recommendation:

  • Access the full 2024 Kubernetes Benchmark Report from Fairwinds (not just the CNCF blog summary)
  • OR remove this statistic if full report unavailable
  • OR search for alternative source that confirms 75% Helm adoption

2. ⚠️ "70% running service mesh" (Line 59, 84, 135)​

Source cited: CNCF Survey 2024 Issue: The CloudNativeNow article cited does NOT mention service mesh adoption rates

Recommendation:

  • Find correct CNCF source that supports this statistic
  • OR remove if source cannot be found
  • Alternative: The article mentions service mesh adoption DECLINED from 50% in 2023 to 42% in 2024 (from CNCF Annual Survey)

3. ⚠️ "3-5x typical underestimation" (Line 81, 106)​

Source cited: Episode 00014 Issue: Cannot verify without checking podcast episode content

Recommendation:

  • Verify this claim appears in Episode 00014 transcript/script
  • OR change to "teams frequently underestimate costs by multiple factors" without specific multiplier
