Take the AWS Solutions Architect Associate first unless you already work with Google Cloud every day. AWS has roughly three times the job openings, a gentler exam, and a cheaper entry point — and the architecture skills you learn transfer directly to Google Cloud later. The GCP Professional Cloud Architect is the stronger second certification, not the starting one. Here is the full comparison so you can decide with real numbers instead of marketing.
Every certification guide on this topic starts with the same framing: two associate-level architect exams, two clouds, one choice. But the choice is not really about which cloud is better. It is about which certificate gets you hired sooner, costs less to earn, and teaches skills that stay useful if you switch clouds later. On all three counts, the answer is usually AWS first — with one important exception I will get to below.
What Does Each Certification Actually Test?
The AWS Certified Solutions Architect – Associate (SAA-C03) tests whether you can design systems on AWS: pick the right storage, design a resilient network, choose between compute options, and keep costs under control. It is a multiple-choice exam with 65 questions in 130 minutes, and it expects you to know the major AWS services well enough to choose between them — not to configure them from memory. You need about six months of hands-on AWS experience, though many candidates pass with three months of focused lab work.
The Google Cloud Professional Cloud Architect (PCA) tests the same kind of thinking on Google Cloud, but it goes deeper. It asks you to design whole solutions — including networking, security, compliance, and operations — and several questions are case studies: long business scenarios where you must recommend an architecture and defend the trade-offs. The exam is two hours, costs $200, and Google recommends three or more years of industry experience, including at least one year designing solutions on Google Cloud. That recommendation is not a formal requirement, but it tells you who the exam is written for: working architects, not beginners.
The practical difference is this: the AWS exam asks “which service solves this problem?” The GCP exam asks “which whole design solves this business problem, and what will it cost and break?” That second question is harder, and it is why the GCP exam has a reputation as the tougher of the two.
Which Exam Is Harder?
The GCP Professional Cloud Architect is the harder exam — and it is not close. Candidates who hold both routinely say so, and the structure explains why. AWS gives you multiple-choice questions about individual services; you can often eliminate two answers immediately because they are obviously wrong for the scenario. GCP gives you case studies where two or three answers are all technically workable, and you must pick the one that best fits the business constraints. That is a design judgment test, not a memory test.
Pass rates are not published by either vendor, but community surveys consistently put first-attempt pass rates for the AWS Solutions Architect Associate around 60–70% for prepared candidates, and for the GCP Professional Cloud Architect closer to 40–50%. The GCP exam also expires after two years (AWS gives you three), so you will be retaking it sooner.
None of this makes the GCP certification a bad goal. It makes it a bad first goal. Passing a hard exam as your first certification is a slow, expensive way to start a career — and a failed first attempt is the single most common reason people abandon certification altogether.
Which One Pays More?
On salary, the GCP Professional Cloud Architect wins — on paper. Global Knowledge’s IT skills and salary surveys have repeatedly ranked it the highest-paying cloud certification, with average reported salaries around $170,000–$190,000 in the US. The AWS Solutions Architect Associate typically reports around $130,000–$155,000.
Read those numbers carefully, because they mislead beginners in a specific way. The GCP figure is high partly because GCP architects are rarer and partly because the people who hold the GCP certification tend to be experienced architects who were already well paid — the certification did not cause the salary; the career did. A beginner who passes the GCP exam does not walk into a $170,000 job. A beginner who passes the AWS exam and lands a $90,000–$110,000 cloud role has made the better financial move, because they are earning while the GCP-only candidate is still studying.
The honest salary comparison is this: GCP pays more at the top end, AWS pays sooner at the entry level, and by the time you hold both, the difference between them is small.
Which One Do Employers Ask For More?
This is where the decision becomes simple. On major job boards, AWS skills appear in roughly three times as many cloud job postings as Google Cloud skills. That ratio has been stable for years: AWS holds about a third of the cloud infrastructure market, Azure about a fifth, and Google Cloud about a tenth. Employers hire for the cloud they already run, and most of them run AWS.
Search your own local job market before you decide — the ratio varies by city and industry. If you live near a cluster of companies that run on Google Cloud, or you already work somewhere that does, the numbers shift. But for most people, in most places, an AWS certification will match more job adverts than a GCP one. One certification on your CV is worth more when it matches the jobs you are actually applying for.
Which Should You Take First? The 60-Second Test
If you are still unsure, answer these three questions honestly:
1. Does your current employer (or your target employer) run on Google Cloud? If yes, take the GCP exam — matching your employer’s stack beats every other consideration.
2. Are you starting from zero, with no cloud job yet? Take the AWS Solutions Architect Associate first. It is cheaper ($150 vs $200), easier to pass, matches more job adverts, and teaches architecture thinking you can reuse on any cloud.
3. Do you already hold the AWS Solutions Architect Associate? Then the GCP Professional Cloud Architect is an excellent second certification — it deepens your design skills and makes you one of the rarer candidates who can architect on two clouds.
For almost everyone reading this, the answer is the second row: AWS first, GCP second. That sequence is also the cheaper path in total — you spend $150 on a passable first exam, get hired, and then your employer often pays for the GCP exam anyway.
The Real Lesson: Learn Architecture, Not Just One Cloud
Here is the part certification guides rarely say out loud: the two exams teach mostly the same skill. Designing for high availability, choosing storage by access pattern, separating public and private networks, planning for failure — these are architecture principles, and they are identical on AWS and Google Cloud. Only the service names change.
That is why the order matters less than people fear, and why the AWS-first sequence works so well. Pass the AWS exam and you have learned 80% of what the GCP exam tests, plus a certificate that gets you hired. Then, when you study for the GCP exam, you are translating knowledge you already own instead of starting from zero. Most people who hold both say the second exam took half the study time of the first — and that is the real efficiency argument.
Start with AWS. Get hired. Then add GCP when you are being paid to learn.
Frequently Asked Questions
Is the GCP Professional Cloud Architect worth it if I already have the AWS Solutions Architect Associate?
Yes — it is one of the best second certifications in cloud. It proves you can design on a second platform, it deepens your architecture judgment through its case-study format, and it puts you in a smaller, better-paid pool of multi-cloud architects. The mistake is taking it first, not taking it at all.
How long does it take to prepare for each exam?
For someone with basic cloud familiarity, the AWS Solutions Architect Associate takes about 6–8 weeks of part-time study (8–10 hours a week), mostly hands-on labs and practice exams. The GCP Professional Cloud Architect takes 10–12 weeks for the same person, because the case studies demand real design practice, not just service knowledge. If you already hold the AWS certification, budget 4–6 weeks for the GCP exam.
Can I take both exams, and in what order?
You can, and the recommended order is AWS Solutions Architect Associate first, then GCP Professional Cloud Architect. The AWS exam builds your foundation and gets you hired; the GCP exam builds on it. Taking them in the reverse order means your first exam is the harder, more expensive one, with fewer job adverts waiting on the other side.
Which certification is better for a career change into cloud?
The AWS Solutions Architect Associate, by a clear margin. It matches more entry-level and mid-level job adverts, it is the certification hiring managers most often name as a requirement, and its study material is the most abundant and cheapest. Pair it with one small deployed project and it is the strongest single credential a career changer can earn in their first year.
