AWS interview questions and answers for experienced scenario based
Here are some AWS interview questions along with scenario-based answers for experienced candidates
1. How would you design a highly available and fault-tolerant architecture on AWS?
I would utilize multiple AWS services to design a resilient architecture. For example, I would deploy my application across multiple Availability Zones (AZs) within a region to ensure high availability. I would use Auto Scaling groups to dynamically adjust the number of instances based on demand and spread them across AZs. Additionally, I would leverage AWS Elastic Load Balancing to distribute traffic evenly across instances, and Amazon Route 53 for DNS failover. Implementing services like Amazon RDS Multi-AZ for database redundancy and Amazon S3 for durable storage would further enhance fault tolerance.
2. Describe how you would implement a scalable data processing pipeline on AWS.
I would architect the data processing pipeline using AWS services like Amazon Kinesis for ingesting and streaming data, AWS Lambda for serverless data processing, and Amazon S3 for storing intermediate and processed data. I would design the pipeline to scale horizontally by using services like…
