Latest Cloud Computing Interview Questions 2025

Beginner Level cloud computing interview questions

1. What's Cloud Technology?

Through the Internet, a Cloud offers virtual space where users have the capability to store digital items, including software, operations, and files.

Cloud computing technologies make it possible to provide computing services—like networks, storage, databases, software, analytics, and intelligence—through the internet. This allows users to pierce and partake of digital coffers across the Internet without being limited by physical position. Regardless of physical location, users are able to share digital resources by using the Internet. 

2. Describe the Cloud Computing Architecture.

The overall cloud computing architecture integrates principles from both service-oriented architecture (SOA) and event-driven architecture (EDA).

It includes factors similar to customer structure, operations, services, runtime Cloud, storehouse, structure, operation, and security. Cloud computing architectures are of two main types:

Frontend

In a cloud computing system, the client side is simply called the frontend. This is comprised of all the user interfaces and applications through which a client can access cloud computing resources and services.

Backend

The backend is the Cloud itself, controlled by the service provider.

It includes the necessary resources, manages them, and ensures security mechanisms are in place.

3. Name the major Cloud Computing Architecture players.

In the Cloud  computing architecture, there are five main actors

- Cloud Provider
- Cloud Carrier
- Cloud Broker
- Cloud Auditor
- Cloud Consumer

4. What are some interview questions about eucalyptus in cloud computing?

A storage platform that utilizes Structure as a Service (IaaS), Eucalyptus is an open-source software framework for cloud computing that is based on Linux.

It offers computing services that are quick and effective. Eucalyptus was developed to offer services comparable to those offered by Amazon's Simple Storage Service (S3) and EC2 Cloud. Both private cases and Amazon Web Services can be supported by Eucalyptus CLIs. The migration of cases from Eucalyptus to Amazon Elastic Cloud is open to visitors.

5. Differentiate between Edge Computing and Cloud Computing?

Edge Computing	Cloud Computing
Edge computing is a distributed computing architecture that gathers computation and data storage near the data source.	Cloud computing is one way that information technology services are delivered online.
Data processing from the data-generating device occurs at the network edge.	A data center is where data processing and analysis take place at a single point.
As there will be specialized hardware and software required at the edge, Edge Computing is more expensive.	As customers pay only for what they consume, Cloud Computing is cheaper.
Scalability for Edge Computing might be harder since more computing resources would have to be added to the edge.	Consumers can scale up or down their computing resources with ease according to their requirements.

6. Difference Between a Cloud and a Data Center

Cloud	Data Center
A virtual resource called the cloud aids companies in effectively storing, organizing, and using data.	A data center is a tangible asset that aids companies in effectively storing, organizing, and using data.
Less money is needed because of the cloud's scalability.	The scalability of the data center necessitates a substantial investment, in contrast to the cloud.
Compared to service providers, maintenance costs are lower.	Because the organization's developers handle upkeep, the cost is considerable.
The cloud is seen as a practical choice and is simple to use.	Data centers are seen as an unfeasible choice and require skilled developers to manage.

7. What are Public Cloud and Private Cloud?

Intermediate-level cloud computing interview questions

1. What's the difference between IAAS, PAAS, and SAAS in cloud computing interview questions?

- IAAS: In cloud computing, Infrastructure As A Service (IAAS) is a way to provide computer infrastructure as on-demand services. Platform As A Service (PAAS) is a cloud delivery mechanism for cloud computing applications that are composed of services under third-party control.

- PAAS: Platform As A Service (PAAS) is a cloud delivery model for applications built of services controlled by a third party in cloud computing.

- Software As A Service (SAAS) is a software model that is implemented as a hosting service that enables consumers to execute pre-existing internet applications in cloud computing. 

2. Which Cloud Computing Security Control Types Are Included in Cloud Computing Interview Questions?

There are four different kinds of security controls for cloud computing.

- Deterrent Controls: The purpose of deterrent measures is to prevent malicious attacks on a cloud system. These are helpful when there are insider attackers.

- Preventive Controls: By removing malware in the system, preventive controls increase its resistance to attacks.

- Security threats and control: Network security monitoring tools and intrusion detection software are a couple of instances of detective control software.

- Corrective Controls: These measures are triggered in the case of a security breach. They lessen the harm that the attack can do.

3. What's "serverless cloud computing," and what are its use cases?

Developers can focus solely on creating code with serverless cloud computing, a cloud computing approach in which the cloud provider handles resource allocation, scaling, and organization. As a result, explicit server management is no longer necessary.

Crucial features of serverless cloud computing include pay-per-use pricing, automatic scaling, and no need for server maintenance.

Use cases for serverless cloud computing include:

- Scalable RESTful APIs are created by API/backend using services like Google Cloud Functions, Azure Functions, and AWS Lambda Functions.
- These APIs carry out business logic, communicate with databases, and provide clients with data.
- Event-driven operations: Handle real-time data from IoT-based or stoner users' actions. 
- Functions can be triggered off at specific times or under certain conditions, like transferring a dispatch when a certain temperature is reached.
- Batch jobs run listed tasks, similar to generating reports.

4. Name some strategies for optimizing and managing Cloud costs

There are a number of ways that can be employed to minimize Cloud expenses.

- Utilities such as AWS Cost Explorer, GCP Billing, or Azure Cost Management to monitor usage trends and expenditure behavior observe usage of resources.

- Establish spending limits and set up notifications to alert you whenever spending goes over the limit.

- Identifying and terminating idle or cost-inefficient resources.

- Assign tags to track cost attribution across projects or teams for the implementation of resource tagging. 

- Use surplus compute capacity at discounted rates for non-critical tasks to leverage spot instances.

- Cloud-native services adoption can manage services instead of provisioning the entire infrastructure. For example, using AWS RDS instead of running a self-managed database.

- With appropriate pricing models committed to long-term use, predictable workloads get discounts compared to on-demand pricing. Use flexible plans like AWS Savings Plans to save on compute usage across different instance types.

- Regularly review and refactor product architecture. Conduct periodic cost reviews to identify inefficiencies in your architecture that are inducing cost or latency.
