AWS SAP-C02 Architecture Scenarios Guide (2026)
The AWS Certified Solutions Architect – Professional exam is not a trivia contest about AWS services. It assesses your ability to think like an enterprise architect: to understand a complex business situation, identify constraints and goals, evaluate multiple valid designs, and recommend the best solution with clear justification. This page introduces the scenario categories you will encounter and provides a repeatable framework for making sound architecture decisions under pressure.
CloudCertPro teaches architecture thinking. You will not find exam dumps or leaked questions here. Instead, you will learn how to approach any scenario—on the exam or in your career—with a structured, principled methodology.
What Is an Architecture Scenario?
An architecture scenario presents a business problem and a set of technical, financial, and organizational constraints. Your task is to design an AWS solution that meets the requirements while respecting the constraints and optimising across the six pillars of the Well‑Architected Framework.
Scenarios typically include:
- Business requirements – What the organization needs to achieve (e.g., migrate 200 servers, launch a global web application, reduce operational costs by 30%).
- Technical constraints – Existing systems, compliance mandates, team skills, data residency rules, network bandwidth limits.
- Non‑functional requirements – Performance targets (latency, throughput), availability SLOs, security posture, disaster recovery objectives (RTO/RPO).
- Trade‑offs – No design is perfect; you will balance cost against resilience, simplicity against security, managed services against control.
The decision flow below illustrates how an architect moves from requirements to a recommended solution.

Enterprise Migration Scenarios
Migrating large on‑premises estates to AWS is a recurring theme. Scenarios often describe a data centre with hundreds of servers, strict timelines, and limited bandwidth.
Typical challenges:
- Legacy systems – Applications that cannot be easily containerised or modernised.
- Large‑scale migrations – Choosing between rehost (lift‑and‑shift), replatform, or refactor based on business goals.
- Database migration – Using AWS DMS and SCT to migrate relational databases with minimal downtime.
- Zero‑downtime migration – Leveraging MGN for continuous block‑level replication, then cutover during a maintenance window.
- VMware migration – Using VMware Cloud on AWS for a rapid rehost with minimal changes.
Architecture lens: You must assess the migration pattern that balances speed, cost, and risk. For example, a short‑deadline migration might start with rehosting and then modernise later (replatform/refactor).
Hybrid Cloud Scenarios
Most enterprises do not abandon their data centres overnight. Hybrid scenarios require you to design environments that span on‑premises and cloud seamlessly.
Key integration points:
- AWS Direct Connect – Dedicated, high‑bandwidth connectivity. Combine with VPN as a cost‑effective backup.
- Identity federation – Extend Active Directory to AWS using IAM Identity Center or AD Connector, enabling single sign‑on.
- Storage Gateway – Present S3 as NFS/SMB shares, use Volume Gateway for iSCSI, and Tape Gateway for backups.
- Hybrid networking – Transit Gateway as the central hub, connecting VPCs, Direct Connect, and VPN attachments.
Architecture lens: You will often design a phased hybrid, where some systems remain on‑premises while new ones run in AWS. The exam tests your ability to integrate DNS (Route 53 Resolver), consistent IP addressing, and security controls across both environments.
Multi‑Region & Global Architecture
When users are distributed worldwide or business continuity demands regional fault tolerance, multi‑region designs become necessary.
- Active‑Active – All regions serve traffic simultaneously. Data is replicated in near real‑time (DynamoDB Global Tables, Aurora Global Database). This provides the lowest latency and fastest failover but at higher cost and complexity.
- Active‑Passive – One primary region handles traffic; a secondary region is warmed for failover. Route 53 failover routing or Global Accelerator detects primary failure and redirects traffic. RPO is typically non‑zero due to asynchronous replication.
Trade‑offs: Active‑active requires global data consistency strategies (conflict resolution) and careful cost analysis. Active‑passive is simpler but introduces failover time and potential data loss. The exam often asks you to select the strategy that meets specific RTO/RPO objectives with minimal cost.
High Availability & Disaster Recovery
High availability (HA) and disaster recovery (DR) are distinct but complementary.
High Availability (within a region):
- Multi‑AZ deployments for EC2, RDS, Aurora, Elastic Load Balancing.
- Auto Scaling to replace failed instances.
- Stateless application design to enable any instance to serve requests.
Disaster Recovery (across regions):
| Strategy | RTO | RPO | Complexity | Cost |
|---|---|---|---|---|
| Backup & Restore | Hours | Hours | Low | Lowest |
| Pilot Light | Tens of minutes | Minutes | Medium | Low‑Medium |
| Warm Standby | Minutes | Seconds | High | Medium‑High |
| Multi‑Site Active‑Active | Near zero | Near zero | Very High | High |
The exam will present a business with specific RTO/RPO requirements and a budget. You must recommend the appropriate DR strategy and describe the AWS services that implement it (e.g., Route 53 failover, S3 Cross‑Region Replication, Aurora Global Database).
Security & Compliance Scenarios
Security architecture is never a standalone domain—it permeates every scenario. You will design IAM policies, encryption strategies, and network controls within broader application or migration contexts.
Common themes:
- IAM and Organizations – Using SCPs to enforce guardrails, setting up cross‑account roles with least privilege, and integrating with external identity providers.
- Encryption – KMS with customer‑managed keys for sensitive data; enforcing encryption in transit with TLS.
- Network security – Implementing defense in depth with WAF, Shield, security groups, NACLs, VPC Flow Logs, and Network Firewall. Using PrivateLink to keep traffic off the internet.
- Threat detection and compliance – GuardDuty for anomaly detection, Security Hub for consolidated findings, Config for resource compliance. Audit trails via CloudTrail.
Architecture lens: You must balance security rigor with operational overhead. For example, using AWS managed keys (KMS) simplifies management but reduces control; customer‑managed keys provide granular key policies but require more administration.
Cost Optimization Scenarios
Cost optimization scenarios test your ability to design financially efficient solutions without compromising core requirements.
Architecture decisions involving:
- Compute – Replacing always‑on EC2 instances with Lambda or Fargate for variable workloads. Using Spot Instances for batch processing and stateless components.
- Storage – Implementing S3 Lifecycle policies to transition data to cheaper tiers (S3 Intelligent‑Tiering, Glacier). Deleting unattached EBS volumes and old snapshots.
- Pricing models – Purchasing Reserved Instances or Savings Plans for baseline capacity. Mixing On‑Demand and Spot for elastic portions.
- Auto Scaling – Dynamically adjusting capacity so you never pay for idle resources.
- Right‑sizing – Continuously evaluating instance families and sizes with Compute Optimizer and Trusted Advisor.
Trade‑offs: The cheapest design may not be the most resilient or secure. The exam asks you to find the most cost‑effective solution that meets stated availability and performance targets.
Modernization Scenarios
Many enterprises have legacy monolithic applications that they want to modernise. SAP‑C02 scenarios will ask you to propose a modernization path.
Common journeys:
- Monolith to Microservices – Decomposing a large application into loosely coupled services, often deployed on ECS/EKS with API Gateway.
- Containers – Migrating applications to containers without a full rewrite (replatform). ECS Fargate removes instance management.
- Serverless – Rewriting components as Lambda functions triggered by EventBridge or API Gateway, achieving maximum elasticity.
- Event‑Driven Architecture – Replacing synchronous point‑to‑point integrations with event buses (EventBridge) and queues (SQS) for resilience and decoupling.
Architecture lens: Modernization decisions are driven by business value: faster feature delivery, improved scalability, reduced operational burden. You must choose the approach that aligns with the organization’s timeline and technical maturity.
How to Analyze SAP‑C02 Scenario Questions
Adopt a consistent, repeatable process to avoid being overwhelmed by lengthy case studies.
- Understand business objectives – Read the scenario and highlight the company’s strategic goals. What outcome are they trying to achieve?
- Identify constraints – Note technical limitations (existing systems, skills), compliance requirements (HIPAA, PCI), and financial boundaries (migration budget, ongoing cost ceiling).
- Determine non‑functional requirements – Extract performance targets, availability SLOs, RTO/RPO, security posture, and scalability needs.
- Generate architecture options – For each major design decision, list at least two AWS services or patterns. Don’t immediately commit to one.
- Evaluate trade‑offs – Compare options against the Well‑Architected pillars. A more resilient option might cost more; a cheaper option might increase operational complexity. Be explicit about what you gain and what you sacrifice.
- Recommend the best solution – Choose the architecture that best satisfies the business objectives and constraints, and be prepared to justify it with data. In the exam, your justification is the correct answer.
This framework transforms a daunting case study into a manageable series of analytical steps.
