30-minute call covering background, cloud certifications (AWS Solutions Architect, Azure Administrator, Google Cloud Architect) and experience with specific cloud platforms.
60-90 minute session with whiteboard or online design challenge. You'll be asked to architect a solution for a real-world scenario (e.g., designing a multi-region disaster recovery architecture, planning a cloud migration).
60 minutes with senior architects discussing your design choices, trade-offs, cost implications, security considerations and how you'd handle non-functional requirements.
45 minutes covering team collaboration, stakeholder management, experience driving cloud adoption programmes and managing difficult project situations.
Cloud architects must demonstrate strategic thinking, stakeholder management and the ability to drive organisational change. These questions assess your soft skills and professional experience.
Cloud architects must master multi-region design patterns, disaster recovery strategies, high-availability principles and the architectural frameworks provided by major cloud providers. These questions test your ability to design resilient, scalable cloud solutions that meet strict non-functional requirements.
Cloud migration is a core responsibility for enterprise cloud architects. Mastering the 6R strategies, application dependency mapping, cutover planning and cloud-native transformation patterns is essential for success. These questions evaluate your ability to plan and execute large-scale migration programmes.
Modern cloud architects must master cost optimisation through FinOps practices, implement robust governance frameworks and navigate multi-cloud trade-offs strategically. These questions assess your ability to optimise cloud spending, enforce compliance and manage vendor relationships.

Start Interview Simulator →Architectural Thinking: Ability to think systematically about system design, understand trade-offs, and make decisions aligned with business objectives. Evaluators assess whether you consider scalability, reliability, security and cost from the outset.
Cloud Platform Expertise: Deep knowledge of AWS, Azure or GCP architectural patterns, managed services, best practices frameworks and when to apply each. Certifications (Solutions Architect, Architect Expert level) demonstrate credibility.
Enterprise Context Understanding: Grasp of large-scale migrations, governance requirements, multi-cloud strategies, compliance frameworks and organisational change management. Enterprise architects must operate at strategic and technical levels.
Communication & Collaboration: Ability to explain complex architectural decisions to both technical teams and business stakeholders. Interviewers assess whether you can facilitate decisions across engineering, security, finance and compliance teams.
Risk & Cost Awareness: Proactive identification of technical risks (single points of failure, data loss scenarios) and cost implications of design decisions. Architects must articulate trade-offs and defend choices with business impact analysis.
Hands-on Validation: Ability to validate architectural decisions through proof-of-concepts, prototyping or hands-on testing. The strongest architects can bridge theory and practice with evidence-based validation.
Cloud architects design cloud infrastructure strategies at an organisational level, focusing on multi-cloud strategy, Well-Architected frameworks, migration planning, cost modelling, compliance architecture and vendor evaluation. Cloud engineers implement those designs, writing infrastructure-as-code (Terraform, CloudFormation), managing CI/CD pipelines, provisioning and operating cloud resources. Architects think strategically about 'what' to build; engineers execute 'how' to build it.
AWS Solutions Architect Associate and Professional certifications are industry-standard credentials. Azure certifications include Azure Administrator and Azure Solutions Architect Expert. Google Cloud offers Professional Cloud Architect certification. Most enterprises value AWS certifications highly. Additionally, consider specialised certifications in security (AWS Security Specialty), data (GCP Professional Data Engineer) or DevOps if focusing on operational architecture. Certifications validate knowledge and enhance credibility; however, hands-on experience designing production systems remains essential.
AWS Well-Architected Framework reviews assess architectures across five pillars: operational excellence (infrastructure-as-code, monitoring), security (access controls, encryption), reliability (fault tolerance, auto-recovery), performance efficiency (right-sizing, caching) and cost optimisation (resource utilisation, purchasing strategies). Reviews typically involve 4-6 hour sessions with AWS architects examining workload design against pillar best practices, identifying risks and gaps. Azure and GCP provide similar framework reviews. These reviews guide architectural improvements and validate design decisions.
Availability vs cost trade-offs depend on business requirements. Multi-AZ deployment adds cost but ensures 99.99% availability. Single-AZ deployments reduce cost by ~30% but risk zonal outages. For critical systems (financial services, healthcare), invest in multi-region active-active architecture accepting premium costs. For non-critical systems (development, testing), single-AZ suffices. Quantify the business impact of downtime—an hour's outage in financial services might cost millions; in internal tools, it might cost thousands. Let business impact drive architectural decisions.
Avoid deep dependency on vendor-specific services: use Kubernetes instead of AWS ECS, PostgreSQL instead of DynamoDB, and Terraform for infrastructure-as-code across clouds. Design portable API layers abstracting cloud-specific implementations. Implement multi-cloud disaster recovery to test portability regularly. However, balance portability against cloud-native performance and cost benefits—over-abstraction reduces advantages. Most enterprises accept some lock-in for strategic services (e.g., machine learning platforms) whilst maintaining optionality in core infrastructure.
Highly available databases typically employ: (1) Multi-AZ deployments with synchronous replication (zero RPO); (2) Read replicas for scaling reads; (3) Automated backup and point-in-time recovery for RTO<1 hour; (4) Failover automation for sub-minute recovery. For mission-critical systems, consider multi-region active-active with eventual consistency (NoSQL) or synchronous replication (acceptable latency). Use managed database services (RDS, Cosmos DB, Cloud SQL) which handle availability complexity. Define RTO/RPO targets first, then select appropriate high-availability patterns.
A Cloud Centre of Excellence (CoE) provides governance, standards and best practices for cloud adoption across an enterprise. Typical responsibilities: establishing cloud architecture standards, defining security baselines, creating reusable reference architectures, managing cloud certifications and training, facilitating cost optimisation, enforcing compliance frameworks and conducting architecture review boards. Effective CoEs balance enabling business velocity with preventing chaos and cost overruns. They serve as internal consultants helping business units adopt cloud successfully whilst maintaining governance.
Success metrics for cloud migrations include: (1) Cost outcomes (TCO reduction, spending forecasting accuracy); (2) Performance (application latency, availability improvement); (3) Velocity (deployment frequency, mean-time-to-recovery); (4) Risk reduction (compliance posture, security incident reduction); (5) Adoption rates (workloads migrated, team cloud certifications); (6) Stakeholder satisfaction (business unit feedback, post-migration support tickets). Measure outcomes 6-12 months post-migration to capture full business impact. Balanced scorecard approach tracking financial, operational and strategic metrics provides comprehensive view of migration success.
