I run a monthly snapshot of cloud-cert salary data pulled from three job boards. Across 2025 and into early 2026, the pattern is consistent: GCP cert holders earn 8–18% less than AWS or Azure cert holders in equivalent roles. This is not my interpretation — it is the median base for roles that specifically mention each cert, adjusted for seniority.
The gap is real. Understanding why it exists matters for anyone deciding which cloud to credential on.
The data
US postings, last 90 days, filtered to senior-level roles requiring the specified cloud cert:
| Role | AWS Pro | Azure Expert | GCP Pro | GCP gap vs AWS |
|---|---|---|---|---|
| Cloud Architect | $178,000 | $170,000 | $158,000 | -11% |
| Cloud Security Engineer | $172,000 | $168,000 | $152,000 | -12% |
| Data Engineer | $165,000 | $162,000 | $148,000 | -10% |
| ML Engineer (cloud-tagged) | $188,000 | $185,000 | $172,000 | -9% |
| DevOps / Platform Engineer | $175,000 | $168,000 | $158,000 | -10% |
GCP lags by 9–12% at the senior level. At junior levels (Cloud Engineer, Associate Architect roles), the gap is smaller — around 5–8%. At executive levels (Director of Cloud Engineering), the gap narrows to ~3% because at that level the cloud-specific cert matters less than the overall leadership track record.
Why the gap exists
Five structural reasons, roughly in order of impact:
1. Market share
Google Cloud sits at roughly 11–12% of the public cloud IaaS market as of 2026 (AWS at 32%, Azure at 24%). Fewer enterprises run workloads on GCP. Fewer GCP-specific jobs exist. Supply of certified candidates relative to demand in each market determines price.
GCP is growing faster than AWS in percentage terms (GCP grew ~30% YoY in 2025 vs AWS ~14%), but absolute market share is still behind.
2. Enterprise penetration
Large enterprises — which pay the highest cloud-engineer salaries — are disproportionately on AWS or Azure. The Fortune 500 is roughly 60% AWS-primary, 25% Azure-primary, 10% GCP-primary, 5% other. Fortune 500 employment has salary gravity. GCP is strongly present in media, ad tech, some financial services, and data-science-heavy companies, but the total Fortune 500 footprint is smaller.
3. Cert recognition outside practitioners
Among practicing cloud engineers, GCP certs carry strong respect. Among hiring managers, recruiters, and HR screening filters — the gatekeepers who write and filter job descriptions — AWS and Azure certs are more recognized. "GCP Professional Cloud Architect" gets fewer automatic resume forwards from HR to hiring managers than "AWS Solutions Architect Professional" does, even though the technical difficulty is comparable.
4. Talent pool concentration
GCP engineering talent is geographically concentrated — Bay Area, Seattle, NYC, and a few other metro areas where ad tech / media tech companies run. The market is thinner outside those areas. AWS talent is distributed across every major US metro. Azure talent follows Microsoft's enterprise footprint, which overlaps most major markets. Geographic concentration reduces optionality for GCP professionals, which reduces salary leverage.
5. Cert versioning and churn
Google deprecates and renames GCP services faster than AWS or Azure. Cloud IoT Core was deprecated in 2023. Google App Engine has gone through multiple phases. Anthos got repositioned. This churn makes older GCP certs feel stale faster than AWS certs do. AWS's reputation for backward-compatible service longevity gives its certs more durable value.
When GCP certs are the right choice anyway
Five situations where the salary gap is the wrong metric:
1. You work at a GCP-primary company already
Pick the cert that matches your daily work. A GCP professional cert at Google, Snap, Twitter, Spotify, Shopify, or Delta makes you better at your job. AWS or Azure certs there would be resume theater.
2. You are in data / ML
GCP's data stack (BigQuery, Dataflow, Vertex AI) is genuinely best-in-class for many use cases. Data engineering and ML roles at GCP-primary companies often pay at parity with AWS equivalents or higher. The gap is smaller in these specific sub-fields.
3. You are in ad tech, media, or telco
These industries over-index on GCP. If your career is in one of them, GCP certification is the specifically relevant credential.
4. You are competing for fewer jobs but less competition
Fewer GCP roles means less hiring competition per opening. If you are in a geo with a handful of GCP employers, a GCP cert can make you the top candidate for each of those openings, whereas an AWS cert makes you one of many.
5. You expect GCP market share to grow
If you think the 30% YoY GCP growth continues and AWS's share erodes 2–3 points over 5 years, GCP cert holders today will be well-positioned for the hiring wave that follows. This is a speculative bet, but it is a reasonable one.
The "take all three" argument
Some candidates pursue certs from all three major clouds. This is the right move for:
- Consultants who advise clients on cloud choice
- Sales engineers at platform-agnostic vendors (Datadog, Hashicorp, CrowdStrike)
- Directors of cloud engineering at companies running multi-cloud
It is the wrong move for most engineering-track candidates. Depth in one cloud beats breadth across three for actual engineering work. The salary premium for multi-cloud is smaller than you would expect (maybe 3–5%) and requires 3x the ongoing renewal cost.
The Azure comparison
Azure's salary parity with AWS surprised me when I first pulled the data. Azure pays nearly as well as AWS despite having smaller market share. The reasons:
- Azure roles are disproportionately at large enterprises (which pay more)
- Azure + Microsoft ecosystem (Power BI, Dynamics, Office integration) creates adjacent-role premium
- Microsoft partnerships with enterprises create a long tail of well-paid consulting roles
GCP does not have this kind of ecosystem-adjacent premium. Its value is more cleanly tied to pure cloud work.
What to do with this information
If you are picking your first cloud cert:
- Default to AWS if you have no compelling reason otherwise. It has the broadest market and the most durable cert value.
- Take Azure if your current or next employer is Microsoft-ecosystem heavy, or you are in enterprise IT where Office/Dynamics/Power Platform matter.
- Take GCP only if you fit one of the five situational cases above.
If you already hold AWS or Azure certs and are considering adding GCP:
- Do it only if your career plan specifically needs GCP knowledge. The salary math does not justify "broadening for broadening's sake."
- Skip the Associate Cloud Engineer and go straight to Professional Cloud Architect if you have other cloud experience. Spend the 80–120 hours on PCA and you have a useful credential.
A note on 2026–2028
GCP's growth trajectory (if it holds) would narrow this salary gap in the next 3–5 years. I expect the gap to be 5–7% by 2028 instead of 9–12%. That still does not make GCP certs a better ROI than AWS or Azure for most candidates in most markets.
The salary gap is a fact, not a judgment. GCP certs are not inferior. They are credentialing for a smaller, faster-growing market where fit matters more than market density. Pick accordingly.
