Cloud Application Engineer Interview Questions and Answers

Developed a cloud-based healthcare application using AWS services for efficient data management and processing.

• Utilized AWS EC2 for scalable compute resources to run the application backend.

• Implemented Amazon S3 for secure and durable storage of patient records and images.

• Used Amazon RDS for a relational database to manage user data and application state.

• Configured AWS VPC for secure networking, ensuring data privacy and compliance with healthcare regulations.

The cloud-based application I worked on had a microservices architecture with containerization using Docker and orchestration with Kubernetes.

• Utilized microservices architecture for scalability and flexibility

• Implemented containerization using Docker for easy deployment and management

• Utilized Kubernetes for orchestration and scaling of containers

• Used cloud services like AWS or Azure for hosting and infrastructure

• Implemented CI/CD pipelines for automated testing and deployment

Key differences include scalability, cost, maintenance, and flexibility.

• Scalability: Cloud architecture allows for easy scalability by adding or removing resources on-demand, while on-premise architecture requires upfront investment in hardware.

• Cost: Cloud architecture typically follows a pay-as-you-go model, where you only pay for the resources you use, while on-premise architecture involves higher upfront costs for hardware and maintenance.

• Maintenance: Cloud architecture sh...read more

I approach troubleshooting methodically, identifying the root cause and implementing solutions while documenting the process.

• Define the Problem: Clearly articulate the issue at hand, such as a service outage or performance degradation.

• Gather Information: Collect logs, metrics, and user reports to understand the context and impact of the problem.

• Isolate Variables: Change one variable at a time, like reverting a recent deployment to see if it resolves the issue.

• Test Solutions: ...read more
