Cloud certification prerequisites
No cloud certification covered on this site requires you to hold another certification first. AWS, Microsoft, Google Cloud, HashiCorp, CNCF and ISC2 all let you book any exam in their catalogue without a prior credential, a course, a degree or an employer’s sponsorship. What vendors publish instead is *recommended experience* — guidance on who the exam was written for, not a gate you have to clear. That distinction matters, because the recommendation is often the more demanding of the two, and it is the one candidates ignore.
Required versus recommended: the distinction that matters
A prerequisite is enforced — the exam cannot be booked without it. A recommendation is editorial: the vendor describing the background the questions assume. Every cloud vendor in this catalogue publishes the second and enforces none of the first, which means the booking page will never stop you sitting an exam you are not ready for.
AWS is the clearest example of the shift. Its Professional and Specialty exams once required an Associate-level certification first; that requirement was removed, and today any AWS exam can be taken in any order. Microsoft, Google Cloud, HashiCorp, CNCF and ISC2 have never gated one certification behind another. The order the certifications are usually taken in is a convention that reflects difficulty, not a rule enforced by anyone.
The recommendation is the real bar — and it is not evenly set
Vendors describe recommended experience per exam, and the gap between the recommendation and the enforcement is widest exactly where it hurts most. A foundational exam is genuinely designed for people with no hands-on background, so the absence of a prerequisite is a fair description of the exam. A specialty exam assumes years of production work in its subject area, and the absence of a prerequisite there simply means nobody will stop you finding that out in the exam room.
Read the recommended-experience paragraph on the official exam page before you book anything above foundational level, and read it as a description of the candidate the questions were written for. If you do not recognise yourself in it, the honest response is to close the gap rather than to discount the paragraph — it is the vendor telling you what the exam assumes you have already done.
What the exam actually checks at the door
The practical requirements are administrative rather than technical: a certification account with the vendor, a booking made through their testing partner, and government-issued photo identification whose name matches your registration exactly. Name mismatches are the single most common reason a candidate is turned away, and they are entirely avoidable — check the name on your certification profile against the document you will bring, well before exam day.
Testing itself happens either at a test centre or online from home, and the online option adds its own requirements: a clear workspace, a supported browser and operating system, and a system check run in advance rather than on the morning. Those requirements change, and they differ by vendor and by testing partner, so the authoritative source is always the vendor’s own exam page rather than any third-party summary — including this one.
What you do not need
You do not need a computer-science degree, a training course, an employer to sponsor you, or professional experience in a cloud role. None of these is checked and none is required. Vendors sell training, and training providers imply necessity, but the only thing standing between you and an exam booking is the exam fee.
You also do not need to take the certifications in a particular order — though for most people there is a sensible one. Starting at foundational level gives you the vocabulary the associate exams assume and a low-cost first pass, which is why it is the usual advice. It remains advice.
