AWS vs Azure vs Google Cloud: Which Certification Should You Get?
All three major cloud providers offer credible certifications, but they are not interchangeable. The right one depends on which clouds employers in your market actually use, what you want to do day-to-day, and how the exams are structured. This is an honest comparison, not a marketing piece.
Market share and job demand
AWS still leads the public cloud market, with Azure a close second and Google Cloud a distant but growing third. In job listings, AWS skills appear in roughly twice as many cloud-engineering postings as Azure, which in turn appears in roughly three times as many as Google Cloud. If you have no preference and want maximum employability, AWS is the safest first certification.
Where each cloud is strongest
Each platform has industries where it dominates and where its certifications carry extra weight.
- AWS — startups, SaaS, e-commerce, media, and most pure cloud-native companies.
- Azure — enterprises, government, healthcare, and any organization built on Microsoft 365 or Active Directory.
- Google Cloud — data engineering, machine learning, analytics, and companies that publicly favor Kubernetes.
How the entry-level exams compare
All three providers offer a beginner certification that assumes zero hands-on experience: AWS Cloud Practitioner, Microsoft AZ-900 Azure Fundamentals, and Google Cloud Digital Leader. AZ-900 has the reputation of being the easiest of the three. Cloud Practitioner is the most respected by hiring managers. Cloud Digital Leader is the most narrowly business-focused — it is closer to a sales-enablement credential than a technical one.
How the associate-level exams compare
The associate tier is where the gap shows up. AWS Solutions Architect Associate is the gold-standard cloud certification globally and the one most often listed in job postings. Azure Administrator Associate (AZ-104) is more operations-focused and assumes you understand Windows Server, Active Directory, and PowerShell. Google Associate Cloud Engineer is the leanest of the three, with shorter exam time and fewer questions, but a stronger emphasis on the gcloud CLI.
Salary differences
Salary surveys for 2025–2026 show all three associate-level credentials clustered in the same band, with AWS slightly higher in the United States and Azure slightly higher in Europe. At the professional level, AWS and Google Cloud tend to outpace Azure on raw salary, while Azure outpaces both on total compensation in large enterprises that pay through bonuses and equity.
Which one should you pick?
Pick AWS if you want maximum job options, are targeting startups or SaaS companies, or have no clear preference.
Pick Azure if you already work in a Microsoft-heavy enterprise, are targeting government or healthcare, or want a slightly easier on-ramp.
Pick Google Cloud if you are doing serious data engineering or machine-learning work, or if you specifically want to work at companies that have publicly committed to Kubernetes and BigQuery.
Can you stack them?
Yes — and many cloud architects do. The most common stack is AWS Solutions Architect Associate plus Azure AZ-104, which signals to employers that you can work in either cloud. Adding Google Associate Cloud Engineer on top is a strong differentiator in 2026 because so few candidates hold all three.
Frequently asked questions
Is AWS certification harder than Azure?
At the entry level, Azure AZ-900 is generally considered easier than AWS Cloud Practitioner. At the associate level the difficulty is comparable, with AWS Solutions Architect Associate being slightly more design-heavy and Azure AZ-104 being slightly more operations-heavy.
Which cloud certification has the highest salary?
AWS Solutions Architect Professional and Google Cloud Professional Cloud Architect typically lead salary surveys, followed by AWS DevOps Engineer Professional and Azure Solutions Architect Expert.
Should I learn all three clouds?
Pick one and go deep first. Once you can confidently work in one cloud end-to-end, a second cloud takes roughly half as long to learn because most concepts transfer.
