Cloud Solutions Architect Interview Prep

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.

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

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

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
