Both of these are intermediate, role-based cloud certifications, and both are excellent first certifications. The decision is rarely about which exam is “better” in the abstract — it is about which cloud platform your target employers run, and what kind of work you want to do.
When AWS Solutions Architect Associate is the better choice
AWS has the largest share of the public-cloud market, and the Solutions Architect Associate is one of the most widely referenced certifications in cloud and DevOps job descriptions. If you are aiming at startups, AWS-first companies, or roles where portability of your credential matters most, start here. The exam pushes you to think like an architect — weighing cost, resilience, security and performance against each other through the Well-Architected Framework — rather than memorising console steps.
When Azure Administrator (AZ-104) is the better choice
Azure is the default in many large enterprises, the public sector, and a large share of German, Austrian and Swiss companies that already run Microsoft 365 and Windows Server. If your local job market or current employer is Microsoft-centric, AZ-104 maps directly onto the work you will actually do — managing identities, storage, compute and virtual networks. It is more operational and hands-on, which some people find more concrete than architecture-style scenarios.
Cost, time and renewal
The exams cost about the same ($150 vs $165) and take a similar 8–12 weeks to prepare for with hands-on practice in a free account. The notable difference is renewal: the AWS SAA is valid three years; AZ-104 expires after one year but renews free online (open-book). Neither cost nor renewal should drive the decision — platform fit should.
What employers actually ask for
Job postings mirror the platform split. AWS-first companies and a lot of the global tech market list AWS certifications; Microsoft-heavy enterprises, the public sector, and much of the DACH/European market list Azure. Look at the actual employers and region you are targeting: the “right” cert is the one their stack uses. Demand for both exists everywhere, but in different proportions by market.
Hands-on matters more than the badge
For either exam, the people who get hired can show they have built something. Spin up a free-tier account, deploy a small real workload (a static site with a CDN, a VM or container, a managed database, a secure network), and be ready to talk through your choices. The certification gets the interview; the hands-on story gets the offer.
The honest answer
If you already know which platform your employers use, that decides it. With no preference, AWS Solutions Architect Associate is the safer default for portability; AZ-104 is the better bet in a Microsoft-heavy region or company. Whichever you pick, the core concepts — identity, networking, storage, compute, cost — transfer, so the second platform is much faster to learn later.
