A recruiter told me something last year that I have not been able to shake. She said that when her firm posts a cloud engineering role, they receive between 300 and 500 applications within the first 48 hours. The first filter is not experience. It is not a degree. It is whether the candidate has a current Microsoft or AWS certification badge on their profile. Everyone without one gets screened out before a human being ever reads their CV.
That single filter eliminates roughly 60 percent of applicants. And the entry-level certification that gets you past it costs $99 and takes 45 minutes to sit.
What the AZ-900 Actually Is
The AZ-900 is Microsoft’s Azure Fundamentals certification—the starting point for anyone entering the cloud computing profession. It covers three domains: cloud concepts like IaaS, PaaS, and SaaS; core Azure services including virtual machines, networking, and storage; and Azure management and governance features like role-based access control and cost management. In October 2025, Microsoft renamed it to “Introduction to Cloud Infrastructure” while keeping the AZ-900 exam code.
The exam is 45 minutes, multiple choice, and does not require any prior IT experience or programming knowledge. It never expires once passed. And it is designed for both technical and non-technical professionals—meaning project managers, sales engineers, and business analysts take it alongside developers and system administrators.
Why a $99 Exam Matters More Than a $120,000 Degree
Here is the uncomfortable math. A four-year computer science degree at a mid-tier American university costs between $80,000 and $160,000. The AZ-900 costs $99. Obviously they are not equivalent qualifications. But in hiring pipelines where automated screening tools filter candidates by certification badges before a recruiter ever sees the application, the $99 credential does something the degree cannot: it gets you past the first gate.
Preparing with an AZ-900 Practice Test before sitting the exam is the most efficient way to learn the question format and identify weak areas. The content is not difficult for anyone with basic technology literacy. What trips people up is the terminology—understanding the difference between a resource group and a subscription, or why availability zones matter for disaster recovery. These are vocabulary problems, not intelligence problems. Practice solves them.
The Numbers Behind the Cloud Job Market
Microsoft claims that Azure is used by over 95 percent of Fortune 500 companies. The global cloud computing market is projected to exceed one trillion dollars within the next four years. Azure-certified professionals earn 7 to 25 percent more than their uncertified peers in the same roles. Azure Cloud Architects with certification average $120,275 compared to $114,770 without it. DevOps Engineers with Azure credentials earn roughly $110,600 versus $105,400 without.
The AZ-900 does not land you an architect role by itself. But it is the foundation that every advanced Azure certification builds upon—AZ-104 for administration, AZ-204 for development, AZ-500 for security, AZ-305 for solutions architecture. Without the fundamentals, the specialisation certifications are significantly harder to pass. The people who skip AZ-900 and jump straight to AZ-104 have a measurably higher failure rate.
The Credential That Opens the First Door
What surprises most people is who is taking the AZ-900. It is not just aspiring developers and system administrators. It is project managers who need to speak the language of their engineering teams. It is sales professionals at technology firms who need to understand what they are selling. It is career changers from completely unrelated fields—teachers, accountants, retail managers—who see cloud computing as a way into a growing industry without going back to university for four years. Microsoft designed the exam to be accessible to all of these people, and the content reflects that: it tests understanding, not technical execution.
My recruiter friend was not being cynical when she described the filtering process. She was being honest about how high-volume hiring works in 2026. When 400 people apply for the same cloud support role, something has to separate them. Certifications are not a perfect measure of competence. But they are the best proxy that automated systems have—and the AZ-900 is the most accessible entry point into that system. Ninety-nine dollars. Forty-five minutes. No prerequisites. No expiration. That is not a bad deal for the key that opens the first door.
