A Comprehensive Guide to AWS Architect Interview Questions
Aws Architect Interview Questions
For an AWS architect interview, you can expect questions related to your experience with designing and implementing scalable, secure, and reliable AWS solutions. Interviewers may inquire about your knowledge of various AWS services, your ability to architect cost-effective solutions, your experience with automation and infrastructure as code, your understanding of networking and security principles in AWS, as well as your problem-solving skills and ability to communicate technical concepts effectively. It's essential to showcase your expertise in designing cloud architectures that meet the business requirements efficiently and align with best practices.

1 - Describe the components of Amazon Web Services (AWS) Global Infrastructure. AWS Global Infrastructure consists of Regions, Availability Zones, Edge Locations, and Direct Connect Locations. Regions are geographic areas with multiple Availability Zones, which are distinct data centers with redundant power, networking, and connectivity. Edge Locations are endpoints for caching content and are used by Amazon CloudFront, while Direct Connect Locations are where you can directly connect to the AWS network.
2) Explain the difference between EC2 and S3 in AWS. Amazon EC2 (Elastic Compute Cloud) is a web service that provides resizable compute capacity in the cloud. It allows you to rent virtual machines (instances) on which you can run your own applications. Amazon S3 (Simple Storage Service), on the other hand, is a storage service that allows you to store and retrieve any amount of data from anywhere on the web. While EC2 provides virtual servers, S3 provides scalable object storage.
3) What is Auto Scaling in AWS and how does it work? Auto Scaling is a feature in AWS that allows you to automatically adjust the number of EC2 instances in a fleet based on criteria you define. This helps ensure that you have the right amount of compute capacity at any given time, while also optimizing cost. Auto Scaling can be based on metrics such as CPU utilization, network traffic, or custom metrics, and it works by launching or terminating instances as needed to maintain the desired capacity.
4) How does Amazon RDS (Relational Database Service) differ from Amazon DynamoDB? Amazon RDS is a managed relational database service that supports multiple database engines such as MySQL, PostgreSQL, Oracle, and SQL Server. It handles routine database tasks like provisioning, patching, backup, and recovery, making it easier to set up and operate relational databases in the cloud. On the other hand, Amazon DynamoDB is a fully managed NoSQL database service that provides fast and predictable performance with seamless scalability. DynamoDB is designed for applications that require single digit millisecond latency and can scale easily to accommodate growing workloads.
5) What are IAM roles in AWS, and how do they improve security? IAM (Identity and Access Management) roles in AWS are a way to delegate permissions to entities that you trust, such as applications or AWS services, without having to share long term access keys. IAM roles allow you to define a set of permissions that an entity can assume to perform specific tasks within your AWS environment. By using IAM roles, you can avoid storing access keys directly within your code or configurations, reducing the risk of unauthorized access to your resources.
