AWS interview questions can feel like you’re taking an oral exam on how to use the AWS (Amazon Web Services) platform, or worse, you’re being quizzed on the meaning of life and the universe. If you’re going into an AWS interview, having to answer AWS questions can be a bit daunting if you don’t know what they are or what they ask. The good news is that most of these questions aren’t hard to answer if you have some solid AWS experience under your belt and you have some practice answering them in an interview setting.

 General questions about Amazon web services

Amazon web services is a cloud computing platform that offers various services, such as storage, networking, and compute power, to help businesses scale and grow. Cloud computing is a way of delivering IT resources and applications over the internet. In other words, it’s the delivery of computing services including servers, storage, databases, networking, software, analytics, and intelligence over the Internet (the cloud) to offer faster innovation, flexible resources, and economies of scale. 

AWS has quickly become one of the world's most innovative and trusted providers of cloud computing services. AWS supports more than 1 million active customers worldwide, including some of the largest global enterprises-companies like Netflix, Spotify, AirBnB, eBay, Expedia-and more than two thousand government agencies and educational institutions. Customers are served by nine regions across 16 geographic areas. These regions provide access to data centers with points of presence in California, Oregon, Washington State, Ireland, Tokyo and Sydney Australia.

 Common technical questions on S3, EC2, Cloud Formation, ECS

Q ) What is S3? 

A) Amazon Simple Storage Service (S3) is an object storage service that offers industry-leading scalability, data availability, security, and performance. 

Q4) What is EC2? 

A) Amazon Elastic Compute Cloud (EC2) is a web service that provides secure, resizable compute capacity in the cloud. It is designed to make web-scale cloud computing easier for developers. 

Q ) What is CloudFormation? 

A) AWS CloudFormation provides a common language for you to describe and provision all the infrastructure resources in your cloud environment. 

Q ) What is ECS? A) AWS Elastic Container Service (ECS) is a highly scalable, high-performance container orchestration service which can automatically scale to meet the demands of your application. 

Q 7) What are containers? 

A) Containers are used to run applications inside isolated operating system environments called containers. They bundle up everything needed to run an application - including code, runtime, system tools, system libraries and other dependencies - into one package. So they offer isolation between different apps as well as deployment flexibility because they're more lightweight than virtual machines.

Q 3) What is the use of AWS Lambda? 

Lambda is a serverless computing platform that allows you to run code without provisioning or managing servers. Lambda can be used for a variety of applications, including web and mobile backends, data processing, batch jobs, IoT, and more. 

Q 4) What are the benefits of using AWS Lambda? 

Some benefits of using Lambda include no need to provision or manage servers, automatic scaling of your application, and high availability. Lambda is also a cost-effective solution since you only pay for the computer time you consume. 

Q 5) What is Amazon S3? Amazon S3 (Simple Storage Service) is object storage service from Amazon Web Services. It provides developers and IT teams with virtually unlimited storage capacity in the cloud where they can store and access any amount of data, at any time, from anywhere on earth. With AWS, customers have access to different tiers of storage which vary in durability, consistency and latency requirements; so they’re able to choose an appropriate storage class depending on their needs. 

Q 6) How does Object Storage work? 

Object storage works by storing objects like files in large clusters on hard disks across multiple servers. Objects are addressed by their unique identifier rather than requiring metadata about who created them or when they were created or modified.
