CLOUD COMPUTING ☁️
🎯 5 Must-Know Cloud Interview Questions
Are you feeling nervous about your first Cloud interview?
With the interview date approaching, you’ve started to wonder, “What kind of questions will they ask?”, “What if I get stuck?” and most importantly “How do I answer confidently without complicating things?”
Cloud computing interviews can feel intimidating, especially if it's your first time. But on the bright side, most interviews cover similar topics. Once you understand the key topics, you’ll feel more comfortable and prepared to sit interviews.
Here are five commonly asked Cloud interview questions:
#1 What is Cloud Computing?
💡 Tip: Think of cloud computing like renting a computer instead of buying one.
Cloud computing is the on-demand delivery of IT resources over the Internet with pay-as-you-go pricing.
This means that instead of purchasing expensive computer hardware and maintaining it yourself, you "rent" computing power, storage, or services from cloud providers like AWS, Google Cloud, or Azure.
#2 What are the different types of cloud models?
💡 Tip: Think of cloud models like different types of housing, some are shared, some are private, and some are a mix of both.
✅ Public Cloud:
This is a cloud environment shared by multiple users, just like renting an apartment. The cloud provider owns and manages the infrastructure, and businesses or individuals "rent" resources as needed.
Example: AWS, Google Cloud, Azure.
✅ Private Cloud:
This is a cloud environment dedicated to a single organization, like owning a house. The organization has full control over security, performance, and customization.
Example: A bank’s private data center.
✅ Hybrid Cloud:
A combination of both public and private clouds. Businesses use this model to keep sensitive data in a private cloud while taking advantage of the scalability of the public cloud for less critical workloads.
Example: Netflix (Uses AWS + Private Infrastructure)
#3 What are IaaS, PaaS, and SaaS?
💡 Tip: Look at it this way - how much control you have over the infrastructure vs. how much the cloud provider manages for you. Here’s an easy diagram to help you remember:
✅ IaaS (Infrastructure as a Service)
You have full control over the infrastructure and need to manage everything yourself, like setting up operating systems and applications.
Example: AWS EC2, Microsoft Azure Virtual Machines.
✅ PaaS (Platform as a Service)
PaaS provides a fully managed platform where developers can build, test, and deploy applications without worrying about underlying infrastructure. The cloud provider handles the servers, networking, and databases.
Example: Google App Engine, AWS Elastic Beanstalk.
✅ SaaS (Software as a Service)
SaaS is a fully developed software application that users can access over the internet without managing infrastructure or platforms. The Cloud provider takes care of everything, and you simply use the software.
Example: Gmail, Dropbox, Microsoft 365.
#4 What is Serverless Computing
💡 Tip: It’s like taking a cab instead of owning a car, you don’t worry about maintenance or parking, just pay for the ride. You make use of servers, but you don’t have to manage them.
Serverless computing lets you run code without worrying about servers. Instead of setting up and maintaining a machine, you just upload your code, and the cloud provider runs it for you.
Example: AWS Lambda, Azure Functions.
#5. What is the Shared Responsibility Model in cloud computing?
💡 Tip: This is about who is responsible for security the cloud provider or the customer? Think of it as renting an apartment, the landlord handles the building, but you manage what’s inside.
✅ Cloud Provider (AWS, Azure, etc.) – Responsible for the security of the cloud (hardware, network, data centers).
✅ Customer (You) – Responsible for security in the cloud (data protection, access control, configurations).
Example: If you store personal data in AWS, AWS secures the servers, but you have to ensure your data is encrypted and access is controlled.
