14 AWS Developer Interview Questions and Answers
Find and hire talent with confidence. Prepare for your next interview. The right questions can be the difference between a good and great work relationship.
What is AWS in your own words?
Your talent should know that AWS is the abbreviation for Amazon Web Services. Amazon provides these AWS services, and they use a specifically distributed IT infrastructure to provide on-demand IT resources.
What type of cloud services is AWS?
The developer should know that AWS is a mixture of three different types of cloud service providers. In their answer, look for the following responses and ask for a few examples of each cloud service to confirm this deeper understanding:
- Software as a Service (SaaS), example includes Microsoft Office365
- Platform as a Service (PaaS), example includes AWS Elastic Beanstalk, Amazon S3 or Redshift
- Infrastructure as a Service (IaaS), example includes AWS EC2 Instance
Why would you use SnowBall?
A skilled AWS programmer should know how to use SnowBall to transfer terabytes of data inside and outside the AWS environment. Understanding how to use this function indicates that the programmer can navigate management controls and set up and provide the functionality to route data inside and outside the application environment.
Describe Regions and Availability Zones in AWS.
Understanding this concept helps when launching different types of programs depending on the region. For example, your coder may want to launch instances in North America to be closer to the North American customers or to meet specific legal requirements within the area. The developer should understand that regions are geographical areas that consist of two or more availability zones, while availability zones are the data centers that can be within the country or the city.
What are AWS edge locations used for?
Make sure that the developer knows that AWS edge locations are not the same as regions or availability zones. Edge locations are AWS data centers designed to deliver services with the lowest latency possible. Your talent should know that these locations are more typically found in major cities for quick responses and load times.
Why would you use CloudWatch?
A contractor should understand CloudWatch and how it helps monitor AWS environments like EC2, RDS Instances, and CPU utilization. Familiarity with CloudWatch shows that the developer knows how to set up alarms that trigger depending on the instance type and various metrics.
How would you set up a system to monitor website metrics within real-time AWS?
While there can be a few answers to this question, a skilled contractor should be using Amazon CloudWatch and AWS Cloudtrail to monitor the status of various services. Look for some of these specific metrics that can be monitored within real-time AWS:
- Amazon EC2 changes
- Auto-scaling lifecycle events
- Scheduled and automation events
- Console authentication sign-in events
- API calls
Why is there a cap on elastic IPs?
A skilled AWS programmer should know the max elastic IP number, because if you need more, you must submit a request for additional Elastic IPs to Amazon. In AWS, the max elastic load you can have per AWS account is five.
What is a load balancer?
Your talent should be able to describe the functionality of a load balancer as a virtual machine that balances your web application load. This internet gateway balances multiple servers so that no operating systems or servers get overwhelmed. Understanding this concept shows that the developer understands how to keep systems functioning properly and safely.
Explain how the elastic block store works
Understanding elastic volume and elastic block store (Amazon EBS) are two features that provide a block storage volume for EC2 instances in the AWS cloud. A contractor who understands how this storage works can tune performance metrics, increase storage, and change volume types without any hiccups within the workload. In addition, working within the elastic block offers elastic IP addresses with high durability and low-latency performance required to run workloads.
What are the real-time benefits of using AWS services?
A skilled contractor should be able to extrapolate how AWS offers multiple types of scalable storage opportunities allowing businesses to make their own decisions. A well-formed answer should include that AWS provides a simple storage service with email services for large amounts of archiving and data storage within a virtual private cloud.
Is AWS open source and free to use?
Since its inception, Amazon Web Services (AWS) has been a place for customers to create tutorials and build open-source management consoles within the cloud. Your talent should be able to define AWS’s past and also lay out the pricing structure. While some AWS services are free of charge to specified limits, they offer pricing for various tiers of Amazon s3, security groups, computing services, and Amazon CloudFront content delivery. A skilled coder has typically used every free and paid feature of the AWS platform.
What is auto scaling?
A suitable contractor should be able to understand auto-scaling and how it is a feature in AWS that automatically scales the amount of data to a steady level. They should be able to describe that when you use the Amazon EC2 auto-scaling group, you can also create a template to scale additional resources built for AWS services.
Do you need to have coding experience for AWS cloud computing?
While AWS developers should be familiar with Java and Python, knowing how to operate within a data warehouse is not required for proficiency with AWS resources. However, understanding the fundamentals of DevOps and the basics of key pairs, SQL, and storage classes will help the user better understand AWS functionality.

Candidate InterviewingB2B MarketingWhite Paper WritingWritingArticle WritingCase StudiesTechnical WritingBusiness WritingEngineering & ArchitectureEbookWhite PaperFor last decade, I’ve helped Fortune 500 companies and Silicon Valley startups draw out the human side to every story, translating complex innovations into clear, impactful narratives. I’ve always lived through writing, ever since I was an angsty adolescent with a journal, a literary-minded teenager writing A+ essays, an engineer crafting environmental impact reports, a nomadic backpacker blogging about mythic forests and technicolor markets, a trade journalist, then a B2B tech writer. My writing wasn’t always perfect. But it had *voice* and *character*. And it was that very voice and character that I hoped to share with others to add value to their endeavors - be it business or otherwise. The dawn of the AI era, which promised to automate the written word to free up our minds to focus on more important endeavors, has in effect diminished the written word, and eroded critical thinking skills. The internet has been flooded by fake, voiceless, indistinct writing that at this point carries a stigma for those who dare to publish it. It’s my belief that veritably human tech writing, even if clunky and imperfect, will bring value to your business in 2026 and beyond. WHY WORK WITH ME? ✔ Engineering + Journalism Expertise – I’m a trained engineer with a background in business journalism, giving me the rare ability to both UNDERSTAND your technology and TELL its story effectively. ✔ Deep Technical Fluency – I specialize in breaking down complex concepts into engaging, digestible narratives that speak to investors, stakeholders, and technical buyers alike. ✔ Global Perspective – My experience spans diverse industries and regions, allowing me to integrate policy, economic, and geographical context into my work. Deliverables: 📌 White Papers & Thought Leadership 📌 Case Studies & Customer Success Stories 📌 Market Intelligence Reports 📌 Technical Blogs A Few of the Industries I Serve: Military Communication Technology — AI Construction Takeoff & Estimating Software— Healthcare B2B IT Software — AI Rental Market Software — Venture Capital Investor Guide — IoT Security Strategy — ETL — Cloud Migration — Smart Transportation Networks — Software User Guides — Smart Building Systems/ IoT powered HVAC — Nonprofit Fundraising Software Let’s create content that informs, influences, and drives action.
