Cloud Solutions Architect Interview Prep
Module Overview
As the Cloud Solutions Architect for a cross-functional application development and operations team, you are responsible for designing and implementing a cloud platform that supports the entire application lifecycle — from development through production and operations.
This project emphasizes architectural decision-making, trade-offs, scalability, security, cost optimization, and hands-on delivery using Terraform, aligned with AWS Well-Architected Framework principles.
Who Should Take This Module?
This module is for:
• Aspiring or practicing Cloud Solutions Architects
• Engineers preparing for AWS Solutions Architect interviews or certification
• Senior cloud engineers transitioning into architecture roles
• Professionals who want to demonstrate design + implementation ownership
The Learning Experience
By completing this project, you will be able to:
• Translate business requirements into scalable AWS architectures
• Apply AWS Well-Architected principles in real-world scenarios
• Implement full-stack cloud architectures using Terraform
• Make and explain architectural trade-offs (cost, performance, reliability)
• Design secure, governed, and resilient application platforms
• Confidently lead architecture discussions in interviews and whiteboard sessions
Full Module Curriculum
1. Application-Led Architecture & Requirements
• Collaborated with developers and operations to gather functional and non-functional requirements
• Translated business, performance, and availability needs into a multi-tier AWS architecture
• Applied AWS Well-Architected pillars to guide design decisions
Key focus: requirements-driven design and architectural reasoning
2. Infrastructure as Code (IaC) — Platform Implementation
• Implemented the architecture using Terraform
• Built reusable, version-controlled Terraform modules
• Deployed:
- VPC with public and private subnets
- Route tables and internet/NAT gateways
- EC2 compute layer
- Application Load Balancer (ALB)
- Auto Scaling Groups
- IAM roles and policies
- • Ensured repeatability, traceability, and safe infrastructure changes
Key focus: consistency, automation, and environment parity
3. Data & Storage Architecture
• Designed and implemented application data services
• Deployed:
- Amazon RDS / Aurora for transactional workloads
- Amazon S3 for object storage and backups
- • Implemented:
- Backup and restore strategies
- Durability and availability considerations
- Disaster recovery (DR) scenarios
Key focus: data reliability, durability, and recovery planning
4. Security & Governance
• Defined security guardrails across the platform
• Implemented:
- IAM least-privilege roles and access boundaries
- Network security controls (security groups, routing isolation)
- Encryption at rest and in transit
- Baseline compliance and governance controls
- • Ensured security was embedded into the architecture, not added later
Key focus: secure-by-design architecture and governance
