Cloud security is a set of practices and tools created to address both internal and external security threats to businesses. As they implement their strategy for digital transformation and integrate cloud-based tools and services into their infrastructure, organizations need cloud security. In recent years, the phrases "digital transformation" and "cloud migration" have become commonplace in business contexts. Both phrases are motivated by the need for change, even though their meanings can vary depending on the organization.

Before we start the interview questions, let us first learn the most common and widely adopted cloud computing services. They are:

  • IaaS (Infrastructure-as-a-Service) is a hybrid approach in which businesses can manage some of their data and applications on-premises while entrusting cloud service providers to take care of their server, hardware, networking, virtualization, and storage requirements.
  • PaaS (Platform-as-a-Service): Provides a unique application framework that automatically appears to be able to operate operating systems, software updates, storage, and infrastructure networks in the cloud. This enables organizations to streamline their software development and delivery.
  • Software-as-a-Service, or SaaS, refers to cloud-based applications that are hosted online and typically made available via subscription. The management of all potential technical issues by third parties, including data, middleware, servers, and storage, reduces the use of IT resources and streamlines upkeep and support tasks.

As it is quite obvious, the world of  Cloud security is abundant with opportunities. Therefore, the demand and competition for the same is a lot in the market. We suggest you to further read this blog to be able to get an idea of the questions that will be asked so that you can ace the interview.

For clarity, the questions are divided into 2 categories, they are:

  1. For freshers
  2. For experienced
  3. FAQ

Frequently Asked Cloud Security Interview Questions

Top Interview Questions for Cloud Security: Freshers

1. What databases are available on open-source cloud computing platforms?

The three primary open-source databases for cloud computing are Lucid DB, CouchDB, and  MongoDB (DB denotes databases). It is one of the most commonly asked interview questions about cloud security that you might encounter. Because the interviewer might have additional questions about those databases, you should identify the cloud computing console databases that you've worked on.

It is obvious to prepare for this type of question while trying to prepare other Cloud Security Interview Questions because cloud features and characteristics are crucial in cloud computing.

10. What do community and hybrid clouds mean?

As the name suggests, hybrid clouds are made up of both public and private clouds. A hybrid has various service providers as a result. For instance, a business may decide to implement SaaS applications across the board; as a result, the firewall (private cloud) will provide the necessary security, and a VPN will provide additional security (public cloud) However, when several businesses are prepared to share the advantages of the cloud, they use a community cloud service. Since the cloud offers advantages for both privacy and security, businesses with similar requirements frequently agree to share the same.

11. How do Amazon Web Services use buffers?

The use of a buffer improves a system's resistance to traffic or load. It aids in the synchronization of various parts. The buffer assists in maintaining the harmony between those elements and also ensures that they operate at the same speed to complete the task more quickly.

12. Do you understand SQS on Amazon?

The answer is that different Amazon components use Amazon SQS messages to connect with different connectors. As a result, it is possible to say that Amazon SQS serves as a mediator.

13. What optimization techniques are used in the cloud?

The optimization method is a very intriguing one. In cloud computing, there are three data center concepts to help with resource optimization and maintenance costs. In the event of a system failure or disaster, this offers recovery and backup, preserving the data safe and secure.

14. Why, in your opinion, is it important for an organization to manage workloads?

Workloads are specifically defined as separate sets of programs or directions that can be run to complete a given task. It might make up the entire application or just a small portion of it. Consequently, an organization is likely to oversee these for the reasons listed below:

  • To determine if the applications are functioning correctly.
  • They are acting in order to understand the functions.
  • In order to be aware of any changes to the services offered by each individual department.

15. How well-versed are you in Windows Azure OS?

To run the application forms on the Windows Azure Platform, a special operating system called Windows Azure is required. All the preconditions for having to run the application forms and hosting them in the cloud are included in the OS. The operating system is renowned for enabling service development before Windows Azure cloud deployment.

16. What role does cloud computing play in IT?

With its advantages, cloud computing has recently swept the globe and the IT industry has been experiencing rapid growth. Cloud computing has now taken over as the mainstay of IT, offering everything from services like quicker application development to enormous storage areas and simpler service delivery.

17. According to some, cloud computing can reduce costs. What do you think?

To gauge the candidate's knowledge and focus, the interviewer may use this type of statement-based cloud security interview questions. The best and the main benefit of the cloud is that you don't have to buy it, so that should be the response. By virtue, it is already present. As a result, all you need to do is use the infrastructure that already exists to your advantage. As a result, you only pay for the time you actually use it before switching it off.

18. What stages comprise cloud architecture?

There are four phases in total that make up cloud architecture and they are as follows:

  • Monitoring Phase
  • Shutdown Phase
  • Cleanup Phase

19. What does "EUCALYPTUS" mean?

Elastic Utility Computing Architecture for Linking Your Programs is what it's called.

20. Can you distinguish between cloud computing and computing for mobile devices?

Despite the fact that both of these employ the same idea, they diverge in some ways. Cloud computing is activated through the internet rather than a specific device in this case. The user can now more easily retrieve data as needed. On the other hand, the mobile device runs apps on the distant server, enabling the user to access the storage and manage it as necessary.
