20 interview questions and answers for Amazon UK Solutions Architect role
1. What are the core responsibilities of a Solutions Architect at Amazon?
Solutions Architects design and implement cloud infrastructure solutions, evaluate customer needs, ensure scalability, optimize costs, and collaborate with stakeholders to align solutions with business goals.
2. Can you explain the AWS Well-Architected Framework?
It’s a set of best practices structured around five pillars: Operational Excellence, Security, Reliability, Performance Efficiency, and Cost Optimization, which guides architects in building robust AWS environments.
3. How do you ensure security when designing AWS solutions?
By applying principles such as least privilege access, data encryption, multi-factor authentication, VPC configurations, security groups, and continuous monitoring using AWS CloudTrail and GuardDuty.
4. Describe a use case where you chose serverless architecture.
Serverless is ideal for event-driven applications with unpredictable workloads; for example, using AWS Lambda with API Gateway for a microservices backend to minimize management overhead.
5. What is the difference between EC2 and Lambda?
EC2 provides virtual servers with full control, suitable for long-running processes; Lambda is a serverless compute service for short-lived functions triggered by events.
6. How would you optimize AWS costs for a client?
Implement right-sizing of resources, use Reserved Instances or Savings Plans, monitor with AWS Cost Explorer, and apply automated shutdown of unused resources.
7. What strategies do you use for disaster recovery in AWS?
Multi-region backups, cross-region replication, automated failover with Route 53, and regular DR drills.
8. How do you handle data migration to AWS?
Depending on size and criticality, options include AWS Snowball, Database Migration Service, or direct upload with S3 Transfer Acceleration.
9. Explain how you would design a highly available web application.
Use Elastic Load Balancer, Auto Scaling Groups across multiple Availability Zones, RDS Multi-AZ, and S3 for static content.
10. What AWS service would you use for monitoring and logging?
CloudWatch for metrics and alarms, CloudTrail for auditing API calls, and AWS Config for configuration tracking.
11. Describe a time you had to troubleshoot a complex AWS architecture issue.
(Here, candidates should describe a specific scenario, demonstrating problem identification, root cause analysis, and solution implementation.)
12. What is Infrastructure as Code (IaC) and which AWS tools support it?
IaC allows infrastructure provisioning through code. AWS CloudFormation and Terraform are popular tools to automate and version infrastructure setup.
13. How do you stay updated with AWS service changes?
By following AWS blogs, attending webinars, participating in AWS re:Invent, and regularly experimenting with new features in test environments.
14. How do you approach communicating complex technical solutions to non-technical stakeholders?
By using analogies, focusing on business benefits, avoiding jargon, and providing clear visual aids like diagrams.
15. Explain VPC and its components.
A Virtual Private Cloud (VPC) is a logically isolated network in AWS. Components include subnets, route tables, Internet Gateway, NAT Gateway, and security groups.
16. What is auto-scaling, and why is it important?
Auto-scaling automatically adjusts compute capacity based on demand, ensuring performance and cost efficiency.
17. How would you secure data at rest and in transit on AWS?
Encrypt data at rest using AWS KMS and EBS encryption; secure data in transit with TLS/SSL.
18. Can you explain the differences between relational and non-relational databases in AWS?
Relational databases like Amazon RDS use structured schemas; non-relational databases like DynamoDB are schema-less and handle unstructured data.
19. What is AWS IAM, and how do you manage permissions effectively?
IAM (Identity and Access Management) controls user access to AWS resources using roles, policies, and groups to enforce least privilege.
20. Describe a project where your AWS architecture significantly improved business outcomes.
Candidates should highlight a case with measurable benefits like cost savings, improved uptime, or faster deployment times.
