After all, job candidates who know how AWS works are more desirable to hiring managers who want employees who can be self-sufficient and confident. Here are eight of the most common <a href="https://thinkcloudly.com/aws-iam-interview-questions-and-answers-part-2/" style="text-decoration:none;"><span style="font-size:11pt;font-family:Arial;color:#1155cc;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:underline;-webkit-text-decoration-skip:none;text-decoration-skip-ink:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">AWS interview questions and answers</a><span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;"> that will help you impress your interviewer. <a href="https://thinkcloudly.com/explore-courses/" style="text-decoration:none;"><span style="font-size:11pt;font-family:Arial;color:#1155cc;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:underline;-webkit-text-decoration-skip:none;text-decoration-skip-ink:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;"><img src="https://lh3.googleusercontent.com/XVbYMp456i7uh6J0XgOzh6CNOhnpsOIzmbVgHItMj9WfMoltp_E9g9dGoCnKGthQmApawg4i8LUKkYjBvX84N8FmfTdvrOYPuosd5NTTv4w77FRYT9Jvk7Knhvk0835Xe88k--9e-9iV3WFUQwskWIV3YuF3RvKAjK71q4eEHjpUWdgisiYKb1aX9A" width="558" height="292"></a> <h2 dir="ltr" style="line-height:1.38;text-align: justify;margin-top:18pt;margin-bottom:6pt;"><span style="font-size:16pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;"> Explain what cloud computing is</h2> <span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">Cloud computing is a type of computing that provides shared resources and virtualized infrastructure over the internet. It usually refers to the remote storage, processing, and delivery of data, software, media content and other information over the internet. Cloud computing services are usually provided as a monthly subscription by an online service provider. There are many different models of cloud architecture and implementation in use today. <a href="https://thinkcloudly.com/what-is-aws-amazon-web-services-aws/" style="text-decoration:none;"><span style="font-size:11pt;font-family:Arial;color:#1155cc;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:underline;-webkit-text-decoration-skip:none;text-decoration-skip-ink:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">Amazon Web Services</a><span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;"> or AWS is a list of remote computing services that provide flexible access to various types of web-based products and services, including storage, processing power, databases and information retrieval capabilities for rent on demand. Amazon runs all its own global infrastructure using Amazon Web Services so users don't have to worry about any issues arising from weather or natural disasters. <h2 dir="ltr" style="line-height:1.38;text-align: justify;margin-top:18pt;margin-bottom:6pt;"><span style="font-size:16pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">What are the featured services of AWS? </h2> <span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">As one of the world's leading providers of data services, Amazon Web Services offer robust, fully managed cloud-based servers and storage. They offer over 70 individual products and services that can help individuals, businesses, and government organizations manage their computing resources in a highly-scalable way. <span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">Some of these are well known while others are not. Regardless, any AWS product can be used by anyone in the public with an internet connection. Most people know about Amazon EC2 Auto Scaling which is an effortless way to make the decision on how many resources you need for your application running at any given time. Amazon EMR (Elastic MapReduce) is perfect for data analytics. <h2 dir="ltr" style="line-height:1.38;text-align: justify;margin-top:18pt;margin-bottom:6pt;"><span style="font-size:16pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">What is Amazon EC2?</h2> <span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">With <a href="https://thinkcloudly.com/introduction-to-aws-ec2-elastic-compute-cloud/" style="text-decoration:none;"><span style="font-size:11pt;font-family:Arial;color:#1155cc;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:underline;-webkit-text-decoration-skip:none;text-decoration-skip-ink:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">Amazon EC2</a><span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">, you pay by the hour for a computer system that is fully managed, fault-tolerant, scalable and secure. With the push of a button you can scale up to respond to sudden increases in demand or scale down after your workload subsides. It's ideal for web hosting and provides either hardware or cloud-based software operating systems with a few mouse clicks.  <span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">To top it off, EC2 offers added support features such as load balancing and recovery tools that let you sleep soundly at night knowing that your application is always available and running securely. <h2 dir="ltr" style="line-height:1.38;text-align: justify;margin-top:18pt;margin-bottom:6pt;"><span style="font-size:16pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">What is Amazon EC2 Auto Scaling?</h2> <span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">In case you're unfamiliar with Amazon <a href="https://thinkcloudly.com/understanding-aws-auto-scaling-groups-asg/" style="text-decoration:none;"><span style="font-size:11pt;font-family:Arial;color:#1155cc;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:underline;-webkit-text-decoration-skip:none;text-decoration-skip-ink:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">EC2 Auto Scaling</a><span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">, it's a service that automatically scales the instances in your Amazon EC2 instance groups up or down based on observed load. Essentially, it helps keep your resources in check. So, how does it work? With fleet management in Amazon EC2 Auto Scaling you can automate scaling decisions using preconditions such as CPU utilization and data processing patterns.  <span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">For example, if your application is using too many resources, fleet management will automatically scale out (increase the number of available machines). Conversely, if your application has too few resources allocated to it then fleet management will automatically scale in (reduce the number of available machines). <h2 dir="ltr" style="line-height:1.38;text-align: justify;margin-top:18pt;margin-bottom:6pt;"><span style="font-size:16pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">5) Explain serverless computing</h2> <span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">What is serverless computing? Serverless computing is a type of software architecture for developing and hosting applications that does not rely on individual servers, the traditional unit of deployment. The framework provides scaling, load balancing, and runtime environments for serverless apps.  <span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:700;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">What is the key advantage?  <span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">The key advantage of serverless architectures is that it moves from managing discrete servers to dividing compute resources into independent tasks. Allocating these resources are automated by the backend of the system, so developers can focus on coding their application. For example, an AWS Lambda function automatically triggers when new code is pushed or when an event occurs such as IoT sensor data being sent to an Amazon Kinesis stream.  <span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">One of the disadvantages of this model is that it may be more difficult to diagnose problems in code because there are fewer locations where things might go wrong. It also forces developers to rethink how they handle stateful data and sessions since state has been abstracted away.  <span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">The upside is that many companies have found they can get higher levels of scalability with this type of design which typically means paying less in costs over time. <h2 dir="ltr" style="line-height:1.38;text-align: justify;margin-top:18pt;margin-bottom:6pt;"><span style="font-size:16pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">What is fleet management in Amazon EC2 Auto Scaling?</h2> <span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">Fleet management in Amazon EC2 Auto Scaling is one of the ways you can use a service called Amazon EBS Volume Encryption. With fleet management, you use a tool called a bootstrap configuration file that automatically provisions volume groups across Availability Zones, while the tools that manage it are encrypted by default.  <span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">One thing to note about fleet management is that because the volumes are encrypted, it’s only useful for workloads with sensitive data and no need for high availability. If you’re trying to run workloads without sensitive data, or need high availability, then the best option would be to use Elastic Block Storage (EBS). It's easy to automate your deployments using either CloudFormation templates or Terraform configurations. <h2 dir="ltr" style="line-height:1.38;text-align: justify;margin-top:18pt;margin-bottom:6pt;"><span style="font-size:16pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">Final Thought</h2> <span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">Many of these questions are asked at an Amazon Web Services interview. While there is no one perfect way to prepare for a tech company interview, these questions will get you thinking about your own responses and give you the confidence that you'll need in an on-the-spot situation. Whether you're going through this list with a friend or family member or with yourself, take some time to come up with your own answers and then be sure to ask your friends for feedback. <span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;"> If you can't answer a question after careful consideration, that's okay! In many cases the question is meant to test how well someone can think on their feet and not just answer questions off the top of their head. Remember: it's better to say I don't know than it is to make something up! ``` ```
