51 Scenarios based Interview questions for Cloud Architect profile for Azure & AWS for 5-10 years of experience professional (Part 1)

In this post, I’ll be discussing 8 scenarios-based interview questions for cloud architect profiles for Azure and AWS, with 5-10 years of experience. Each question includes a scenario, the question, its solution, and the services used in order to provide the solution.

#1 Scenario

A company wants to ensure high availability and disaster recovery for their critical applications running on the cloud. What would be your approach to achieve this?

Question: How would you ensure high availability and disaster recovery for critical applications running on the cloud, and what services would you use to achieve this?

Solution: To ensure high availability and disaster recovery for critical applications running on the cloud, I would design a multi-region architecture that spans across multiple Availability Zones or Regions. This would ensure that if one region or availability zone goes down, the application would automatically failover to another region or availability zone. I would use services like AWS Global Accelerator and Azure Traffic Manager to route traffic across multiple regions and availability zones, and services like AWS CloudFormation and Azure Resource Manager to automate the deployment of the infrastructure.

AWS Services: AWS Global Accelerator, AWS CloudFormation

Azure Services: Azure Traffic Manager, Azure Resource Manager

#2 Scenario

A company wants to improve the performance of their web application by caching frequently accessed data. What would be your approach to achieve this?

Question: How would you improve the performance of a web application by caching frequently accessed data, and what services would you use to achieve this?

Solution: To improve the performance of a web application by caching frequently accessed data, I would use a caching solution like Amazon ElastiCache or Azure Cache for Redis. I would configure the caching solution to store frequently accessed data in memory, which would reduce the number of requests that the application has to make to the backend database. This would improve the application's response time and reduce the load on the database.

AWS Services: Amazon ElastiCache

Azure Services: Azure Cache for Redis

#3 Scenario

A company wants to implement a serverless architecture to reduce their infrastructure costs. What would be your approach to achieve this?

Question: How would you implement a serverless architecture to reduce infrastructure costs, and what services would you use to achieve this?

Solution: To implement a serverless architecture to reduce infrastructure costs, I would use services like AWS Lambda or Azure Functions to run code without the need to provision and manage servers. I would also use services like Amazon API Gateway or Azure API Management to expose the serverless functions as RESTful APIs. This would enable the company to build scalable and cost-effective applications without having to worry about the underlying infrastructure.

AWS Services: AWS Lambda, Amazon API Gateway

Azure Services: Azure Functions, Azure API Management

#4 Scenario

A company wants to analyze large amounts of data using machine learning algorithms. What would be your approach to achieve this?

Question: How would you analyze large amounts of data using machine learning algorithms, and what services would you use to achieve this?

Solution: To analyze large amounts of data using machine learning algorithms, I would use services like Amazon SageMaker or Azure Machine Learning to train and deploy machine learning models on the cloud. I would also use services like Amazon S3 or Azure Blob Storage to store the data, and services like Amazon Kinesis or Azure Event Hubs to stream the data to the machine learning models. This would enable the company to gain valuable insights from their data and make data-driven decisions.

AWS Services: Amazon SageMaker, Amazon S3, Amazon Kinesis

Azure Services: Azure Machine Learning, Azure Blob Storage, Azure Event Hubs

#5 Scenario

A company wants to implement a hybrid cloud architecture to leverage both on-premise and cloud resources. What would be your approach to achieve this?

Question: How would you implement a hybrid cloud architecture to leverage both on-premise and cloud resources, and what services would you use to achieve this?

Solution: To implement a hybrid cloud architecture, I would use services like AWS Outposts or Azure Stack to extend the cloud services to the on-premise data center. This would allow the company to use the same tools, APIs, and services to manage both the on-premise and cloud resources. I would also use services like Amazon Direct Connect or Azure ExpressRoute to establish a dedicated and secure network connection between the on-premise and cloud resources. This would enable the company to seamlessly integrate the on-premise and cloud resources and provide a consistent user experience.

AWS Services: AWS Outposts, Amazon Direct Connect

Azure Services: Azure Stack, Azure ExpressRoute

#6 Scenario

A company wants to implement a DevOps pipeline to automate the deployment of their applications to the cloud. What would be your approach to achieve this?

Question: How would you implement a DevOps pipeline to automate the deployment of applications to the cloud, and what services would you use to achieve this?

Solution: To implement a DevOps pipeline, I would use services like AWS CodePipeline or Azure DevOps to automate the build, test, and deployment of applications to the cloud. I would also use services like Amazon Elastic Beanstalk or Azure App Service to deploy the applications to the cloud. I would configure the DevOps pipeline to trigger the deployment automatically when a code change is committed to the version control system. This would enable the company to release new features and bug fixes quickly and reliably.

AWS Services: AWS CodePipeline, Amazon Elastic Beanstalk

Azure Services: Azure DevOps, Azure App Service

#7 Scenario

A company wants to ensure the security of their cloud infrastructure and applications. What would be your approach to achieve this?

Question: How would you ensure the security of a cloud infrastructure and applications, and what services would you use to achieve this?

Solution: To ensure the security of a cloud infrastructure and applications, I would use services like AWS Identity and Access Management or Azure Active Directory to manage user access and permissions. I would also use services like Amazon GuardDuty or Azure Security Center to detect and respond to security threats. I would implement encryption at rest and in transit using services like Amazon S3 or Azure Storage Encryption. I would also use services like AWS WAF or Azure Firewall to protect the applications from web attacks and exploits.

AWS Services: AWS Identity and Access Management, Amazon GuardDuty, Amazon S3,  AWS WAF

Azure Services: Azure Active Directory, Azure Security Center, Azure Storage Encryption, Azure Firewal

#8 Scenario: 

A company wants to migrate their entire IT infrastructure to the cloud. What steps would you take to ensure a successful migration?

Question: How would you approach a large-scale cloud migration project, and what services would you use to ensure its success?

Solution: To ensure a successful migration, I would start by conducting a thorough assessment of the company's existing infrastructure, applications, and data. Based on the assessment, I would develop a migration plan that outlines the scope, timeline, and budget for the project. I would use services like AWS Migration Hub and Azure Migrate to track the progress of the migration and ensure that all applications and data are migrated seamlessly to the cloud.

AWS Services: AWS Migration Hub

Azure Services: Azure Migrate
