SAA-C03 vs AZ-104: AWS Architect or Azure Administrator?
AWS Certified Solutions Architect – Associate (SAA-C03) and Microsoft Certified: Azure Administrator Associate (AZ-104) are the two flagship associate-level cloud certifications — and the most common pair candidates weigh against each other. They are not equivalent exams with different logos: they test different jobs. SAA asks 'can you design the right architecture?', AZ-104 asks 'can you actually run this environment?'.
This comparison covers scope, difficulty, question format, cost, and career positioning so you can pick deliberately instead of by brand loyalty.
The fundamental difference: design vs operate
- SAA-C03 tests architecture judgment — given a scenario with constraints (cost, latency, durability, compliance), choose the right combination of services and patterns. You rarely need console muscle memory.
- AZ-104 tests operational competence — configure RBAC correctly, deploy and manage VMs, fix a broken VNet, implement backup. The exam assumes you've touched the portal and CLI.
- Consequence: SAA rewards knowing WHAT services do and when to pick them; AZ-104 rewards knowing HOW to configure them (exact permission scope, exact redundancy option names, exact networking rules).
Exam logistics compared
- Cost: both $165 USD — identical.
- Questions: SAA ~65 scenario-based questions in 130 minutes; AZ-104 40–60 questions including case studies and labs-style tasks in ~100–120 minutes.
- Passing: SAA 720/1000; AZ-104 700/1000.
- Format risk: AZ-104 has historically included hands-on lab tasks and drag-drop matching — more varied than SAA's pure multiple-choice/response.
Difficulty — which is actually harder?
Most candidates with comparable experience rate AZ-104 slightly harder to pass cold, because it demands operational precision: you can't reason your way to 'which RBAC role at which scope' or 'which redundancy SKU allows zone deployment' — you either know it or you don't. SAA is more forgiving to strong reasoning skills because correct answers follow architectural logic.
The difficulty flips by background. If you already work in Azure daily, AZ-104 is closer to your job. If you're an AWS architect, SAA's design-thinking style will feel more natural than Azure's memorized-operations style.
Concept translation table
- IAM roles/policies → Entra ID + Azure RBAC (note: Azure permissions are additive at scope — no explicit deny except via deny assignments/policy)
- VPC/subnets/route tables/SGs → VNet/subnets/route tables/NSGs (NSG rules have priority numbers and are stateful like SGs)
- S3 storage classes → Blob storage access tiers (Hot/Cool/Cold/Archive)
- Multi-AZ RDS → zone-redundant Azure SQL/VM deployment; AWS AZs ≈ Azure Availability Zones, AWS Regions ≈ Azure geographies/regions
- CloudFormation → ARM templates/Bicep/Terraform; AWS Organizations + SCP → Management Groups + Azure Policy
- CloudWatch → Azure Monitor; CloudTrail → Azure Activity Log
Career positioning
- Job market: SAA appears in more job postings globally — AWS remains the largest cloud by share. AZ-104 dominates in enterprises standardized on Microsoft (Microsoft 365 + Entra shops are overwhelmingly Azure).
- SAA signals you can design systems — better for architect, platform engineer, consultant tracks. AZ-104 signals you can administer them — better for ops, sysadmin, and cloud admin tracks.
- Salary data is roughly equivalent; the differentiator is which ecosystem your target employers run. Check the job postings you'd actually apply to.
Which should you take first?
If your employer runs one cloud, take that cloud's cert — context beats market data. If you're genuinely neutral: take SAA first if you're a developer or aspiring architect (design thinking transfers better), take AZ-104 first if you come from sysadmin/ops or your region's market skews Microsoft.
Planning to take both eventually? Do SAA → AZ-104 rather than the reverse. AWS's architecture-first framing builds the mental model that makes Azure's service catalog easier to absorb afterward.
Where to practice
We maintain free banks for both: the SAA-C03 bank (100 questions) and the AZ-104 bank (40 questions) — plus exam guides, cheat sheets, and study plans for each. If you're deciding, try a mock exam on both and compare which question style frustrates you less.
