Career Roadmap
AWS Solutions Architect: Zero to Hero
This path is about making better architecture decisions, not memorizing services. Build your understanding step by step, validate your SAA-C03 readiness, then develop the judgment needed for SAP-C02's messier, higher-stakes scenarios.
Embark on your career roadmap by setting a target and staying accountable
Set targetStep 0 - Basics
Build enough foundation to understand how cloud systems behave.

Step 0 - Basics
Build enough foundation to understand how cloud systems behave.
- Networking (IP, DNS, load balancing basics)
- Compute concepts (instances, scaling)
- Storage types (block, file, object)
💡 You don't need deep expertise here, just enough to reason through architecture decisions.
Step 1 - AWS fundamentals
Get comfortable with core AWS building blocks.
2-3 weeks2-3 weeks
Step 1 - AWS fundamentals
Get comfortable with core AWS building blocks.
- S3
- EC2
- IAM
- VPC basics
Certifications
💡 Use ExamOS quizzes to confirm you understand IAM, pricing, and core services before moving on.
Step 2 - Core AWS services
Learn how to choose the right AWS service for each scenario.
3-4 weeks3-4 weeks
Step 2 - Core AWS services
Learn how to choose the right AWS service for each scenario.
- Compute (EC2, Lambda)
- Storage (S3, EBS, EFS)
- Databases (RDS, DynamoDB)
- Networking (VPC, Load Balancer, Route 53)
Certifications
💡 Focus on when to use each service, not just what it does.
Step 3 - Identity and security
Add security into every architecture decision.
2-3 weeks2-3 weeks
Step 3 - Identity and security
Add security into every architecture decision.
- IAM roles and policies
- Shared responsibility model
- Security groups and NACLs
- Secrets management
Certifications
💡 Treat security as part of design, not a separate step.
Step 4 - Design thinking
Move from services to system-level thinking.
3-4 weeks3-4 weeks
Step 4 - Design thinking
Move from services to system-level thinking.
- High availability (multi-AZ)
- Scalability (auto scaling)
- Fault tolerance
- Cost optimization
- Ask: What happens if this fails?
Certifications
Step 5 - Data and integration
Design how systems store, process, and move data.
3-4 weeks3-4 weeks
Step 5 - Data and integration
Design how systems store, process, and move data.
- RDS vs DynamoDB decisions
- Data storage strategies
- Messaging (SQS, SNS)
- Event-driven architecture
Certifications
💡 Choose based on workload, not preference.
Step 6 - Monitoring and cost management
Understand system visibility and cost control.
2-3 weeks2-3 weeks
Step 6 - Monitoring and cost management
Understand system visibility and cost control.
- CloudWatch
- Logging and alerts
- Cost Explorer and budgeting
Certifications
💡 Use ExamOS quizzes to validate monitoring and cost-related scenarios. Before moving on, you should be consistently making the right call on trade-offs — not just recognising the right answer when you see it.
Step 7 - SAA-C03 Certification
Validate your associate-level thinking before pushing into professional territory.
1-2 weeks1-2 weeks
Step 7 - SAA-C03 Certification
Validate your associate-level thinking before pushing into professional territory.
- Timed practice exams under real conditions
- Weak area review and repetition
- Architecture explanation practice
Certifications
💡 If you can explain why one architecture is better than another, you are ready. If you are still pattern-matching answers, keep practising.
Step 8 - Enterprise architecture foundations
Shift from designing single workloads to thinking across entire organisations.
3-4 weeks3-4 weeks
Step 8 - Enterprise architecture foundations
Shift from designing single workloads to thinking across entire organisations.
- AWS Organizations and multi-account strategies
- Control Tower and landing zones
- Service Control Policies (SCPs)
- Cross-account access patterns
💡 SAP-C02 assumes you already know the services. This step is about understanding how large organisations structure their AWS environments and why.
Step 9 - Advanced networking and hybrid connectivity
Design networks that span cloud, on-premises, and multiple regions.
3-4 weeks3-4 weeks
Step 9 - Advanced networking and hybrid connectivity
Design networks that span cloud, on-premises, and multiple regions.
- Transit Gateway and VPC peering at scale
- AWS Direct Connect and VPN
- Hybrid DNS resolution
- Network segmentation strategies
💡 Networking questions in SAP-C02 are longer and more layered. A constraint mentioned three sentences ago often changes the answer entirely.
Step 10 - Migration and modernisation
Learn how to move existing systems to AWS and evolve them once there.
3-4 weeks3-4 weeks
Step 10 - Migration and modernisation
Learn how to move existing systems to AWS and evolve them once there.
- Migration Evaluator, MGN, DMS
- The 7 Rs of migration (rehost, replatform, refactor, etc.)
- Strangler fig and phased migration patterns
- Modernising monoliths into services
💡 Every migration scenario has constraints — budget, downtime tolerance, team skill. The right answer depends on those constraints, not on what is technically ideal.
Step 11 - Cost optimisation and governance at scale
Design for cost efficiency across complex, multi-team environments.
2-3 weeks2-3 weeks
Step 11 - Cost optimisation and governance at scale
Design for cost efficiency across complex, multi-team environments.
- Reserved Instances, Savings Plans, Spot strategy
- Tagging and cost allocation
- AWS Budgets and Cost Anomaly Detection
- Governance guardrails across accounts
💡 At professional level, cost decisions are architecture decisions. Build that instinct now.
Step 12 - Architecting for ambiguity
Develop the judgment to handle scenarios where all four answers look defensible.
3-4 weeks3-4 weeks
Step 12 - Architecting for ambiguity
Develop the judgment to handle scenarios where all four answers look defensible.
- Long scenario reading and information triage
- Identifying the real constraint in a question
- Trade-off frameworks (cost vs. performance vs. resilience)
- Explaining your reasoning out loud
💡 This is where SAP-C02 separates candidates. The skill is not knowing more services — it is holding more context and making a more defensible call under pressure. Use ExamOS scenario practice daily to build this instinct.
Final step - Professional certification and validation
Before booking SAP-C02, run multiple timed ExamOS quizzes across all domains, identify where your reasoning breaks down, and drill those areas until your decisions are consistent. The bar is not recognising the right answer — it is being able to defend it. If you can walk through a complex scenario, name the real constraint, and explain why one architecture is more appropriate than another, you are ready.

- 3-4 hours/day: around 5-6 months
- Consistency matters more than long sessions.
