Top Cloud Computing Interview Questions and Answers

1. Explain cloud technology

Cloud computing is all about gathering, storing as well and accessing data when in need. And also showcase with the help of remote servers, which are successfully hosted on the internet. Now you must be wondering what the situation was earlier; everything was created using a computer’s hard drive or a local server. Often known as internet-based computing, in cloud computing, resources are offered using the internet. Here, the term Data can be used in the context of different kinds of files, images, documents, or any other storable document.

2. Describe the Cloud computing architecture

To answer your question, let me consider each performer as an object. Here, there are five main characters defined mainly as:

• Cloud provider
• Cloud carrier
• Cloud broker
• Cloud auditor
• Cloud consumer

3. Explain the different versions of cloud

Well, there are primarily three versions of cloud computing services, such as:

• Public cloud – As the name implies, these kinds of clouds are owned by third parties and successfully manage all types of hardware, software, as well as supporting infrastructure. Microsoft Azure and Amazon AWS are one of the common examples when thinking about public clouds.
• Private cloud – These are single resources that are maintained exclusively by a specific business on a private network. This concept should be absolutely clear since there are high chances of you working on them.
• Hybrid cloud – As the name implies, this type of cloud computing system is a rare combination of private cloud and a public cloud, where apps can be shared for more flexibility.

In addition to this, you can try finding out which cloud model is best for the company and how to enhance outcomes.

4. Difference between cloud computing and cloud elasticity

Cloud scalability is the ability to increase workloads by removing resources to meet workloads within a system’s existing resources. Cloud scalability is used to calculate the increase and decrease of resources, especially when needed, and by adding to existing infrastructure, it is possible to plan peak demand.

Whereas cloud elasticity is totally different, it is an elastic system that can successfully expand and shrink seamlessly to match different kinds of resources in accordance with a business and organisation’s needs. Elastic cloud systems are mainly considered to work wonders for small and public cloud systems.

You can even add whether the company will benefit from scalability or elasticity.

5. What is AWS? What are its top and most recommended features?

AWS, Amazon Web Services, is one of the leading cloud computing platforms offering a wide range of on-demand services such as computing power, storage, and databases, and is highly accessible with the help of the internet.

Right from hosting a website to storing files, running applications, as well as analyzing large data, AWS does all the work. It offers over 200 services such as EC2 for virtual servers, S3 for storing files, RDS for managing databases, and Lambda to run code without servers.

AWS is highly known due to its unmatched features, such as:

• On-demand resources
• Pay-as-You-Go Pricing
• Global infrastructure
• High reliability and performance
• All under one roof

6. Can you ensure data security in a cloud environment?

You need to understand why this question is often asked; it is meant to test your knowledge of security best practices and protocols. As a sure-shot answer, you need to focus on implementing strong encryption methods for both data at rest and in transit. In addition, I would also recommend conducting regular security audits and compliance checks. This is usually done to spot as well as eliminate all kinds of potential vulnerabilities.

• Use strong authentication as a part of the first line of defence against unauthorised access in terms of facial recognition, fingerprints.
• Implementing encryption means encoding data in such a manner that only authorised users can access it.
• Implement Role-based access control
• Keep tabs on cloud activities
• Use secure APIs
• Conduct regular security assessments
