Aws Solution Architect Interview Questions
In an AWS Solutions Architect interview, you can expect questions covering a wide range of topics such as cloud computing concepts, AWS services, architecture design principles, security best practices, scalability considerations, cost optimization strategies, troubleshooting scenarios, and more. Employers will likely test your ability to architect and design scalable, cost-effective, and highly available solutions on AWS, as well as your knowledge of various AWS services and how they can be leveraged to meet specific business requirements. It's important to be well-versed in all aspects of AWS, including cloud architecture, networking, storage, security, databases, and serverless technologies, to succeed in the interview process.

1 - What is AWS, and what are the different services it offers? AWS (Amazon Web Services) is a comprehensive platform offering various cloud computing services, including computing power, storage options, networking, databases, analytics, machine learning, and more. Some key services include EC2 for virtual servers, S3 for object storage, RDS for managed databases, and Lambda for serverless computing.
2) What are the key differences between S3 and EBS? S3 is an object storage service for storing files and data, accessible via APIs. EBS, on the other hand, provides block level storage volumes for use with EC2 instances. While S3 is suitable for storing large amounts of unstructured data, EBS is primarily used for storing data that requires frequent access and a file system.
3) How can you secure data in transit and at rest on AWS? To secure data in transit, you can use SSL/TLS protocols for encryption when transferring data between applications and services. For data at rest, AWS offers services like AWS Key Management Service (KMS) for managing encryption keys, and services like S3 SSE (Server Side Encryption) for encrypting data at rest.
4) What is the difference between horizontal and vertical scaling? Horizontal scaling involves adding more instances or nodes to a system to handle increasing workload, while vertical scaling involves increasing the resources of an individual instance, such as adding more CPU or memory. AWS offers Auto Scaling for horizontal scaling and instance type changes for vertical scaling.
5) How does AWS Lambda work, and what are its use cases? AWS Lambda is a serverless computing service that runs code in response to triggers without the need to provision or manage servers. Developers can upload their code to Lambda and define triggers that initiate its execution. Use cases for Lambda include event driven processing, data processing, automation of tasks, and more.
6) Explain the differences between IAM users, roles, and groups. IAM users are entities with long term credentials that represent a person or machine interacting with AWS resources. Roles are similar to users but are meant for roles rather than individuals, and they can be assumed by users or services. Groups allow you to group IAM users and manage their permissions collectively.
7) How can you monitor and troubleshoot performance issues in AWS? AWS offers services like CloudWatch for monitoring metrics and logs, AWS Config for tracking configurations, X Ray for tracing requests, and CloudTrail for logging API activity. By utilizing these services, you can monitor performance, detect anomalies, and troubleshoot issues in your AWS environment.
