30 Cloud Engineer Interview Questions

30 Interview Questions With Sample Answers

1.   Please discuss the differences between Cloud and On-premise Computing.

How to Answer

This question is requesting you to compare two concepts used in this profession. When answering a question like this, you should first define each concept and then discuss their differences and similarities. You can either list all the features and benefits of one of the concepts, then do the same for the other, or compare them point by point.

Written by William Swansen on October 26th, 2021

Answer Example

"The main difference between cloud and on-premise computing is that cloud computing is off-site and hosted by a service provider while on-premise is managed by the organization, which is responsible for all aspects of the IT infrastructure. The key features of on-premise computing are that there is a high initial investment, the organization is responsible for all the maintenance and support, hardware and software upgrades must be maintained, and scaling the infrastructure can be challenging. On the other hand, Cloud computing has a low initial investment, requires no maintenance or support from the client organization, upgrades are automatic and managed by the service provider, and the infrastructure can be scaled as needed. The disadvantages of cloud computing over on-premise infrastructure are centered around security and control."

2.   What are some of the benefits offered by cloud computing that would induce an organization to adopt it?

How to Answer

An interviewer may ask this question for two reasons. The first is to test your knowledge of cloud computing and confirm that you know some of the benefits it offers. The second is that they may be considering adopting this technology and want to get your opinion of its benefits and why they should move in this direction. Since you are interviewing for a cloud engineer's role, your answer should promote the use of cloud technologies.

Written by William Swansen on October 26th, 2021

Answer Example

"Cloud computing offers many benefits compared to hosting an IT infrastructure on-premise. First, it is cost-effective in that you only invest in the IT infrastructure you need. Since cloud computing scales easily, you can increase or decrease the infrastructure in real-time. Cloud computing also offers organizations access to IT resources they may not be able to afford to either purchase or manage themselves. Another advantage is that the cloud service provider is responsible for the data backup and recovery, which is a key requirement for any organization's disaster recovery plan."

Written by William Swansen on October 26th, 2021

3.   Can you define the 'Cloud' and discuss some of its features?

How to Answer

This is a general question which the interviewer will use to get you talking, learn more about your background, and collect information they can use throughout the interview. This provides you the opportunity to direct the interview towards an area that you are knowledgeable in and comfortable discussing.

Written by William Swansen on October 26th, 2021

Answer Example

"The cloud consists of IT infrastructure that is hosted off-site, typically by a third-party provider. It consists of hardware, software, storage, networking, and IT services. The cloud is managed by a service provider and accessed by users through various devices from virtually any location in the world."

Written by William Swansen on October 26th, 2021

4.   Can you discuss the different types of clouds and how they are used?

How to Answer

If an organization is new to cloud computing, they will be looking to learn about the different features, benefits, and options available within the cloud computing environment. As a prospective employee, they want to test your knowledge of these to determine if you can assist them in selecting the appropriate cloud type for their organization. When responding to this question, keep your answer brief and to the point. The interviewer will ask a follow-up question if they need additional information or explore the topic in more depth.

Written by William Swansen on October 26th, 2021

Answer Example

"There are four main types of cloud environments. These include private cloud, public cloud, community cloud, and hybrid cloud. A private cloud is dedicated to the organization and may be hosted by a third party or maintained by the organization. A public cloud is hosted by a third party, with resources dedicated to individual clients. A community cloud is hosted but shares the resources among multiple clients. The hybrid cloud is a combination of any of these three and offers organizations options and flexibility."

Written by William Swansen on October 26th, 2021

5.   Please talk about how cloud computing can help with the reliability and availability of an organization's IT resources.

How to Answer

As a cloud engineer, you should be able to describe the benefits of cloud computing. One of the key benefits of this technology is helping organizations maintain access to and the availability of IT resources. You should also be able to describe the technology behind these benefits, including specific features. Be prepared for follow-up questions, which the interviewer will use to explore this topic in more depth.

Written by William Swansen on October 26th, 2021

Answer Example

"One of the key benefits of cloud computing is that it provides a higher level of reliability and availability to the users. This is because of its use of fault domains. This technology involves two virtual machines so that if one were to fail, the other would be available. The software will distribute and control computing instances across both VM's, so failover is instantaneous. Fault domains can also be employed when upgrading software by first upgrading one virtual machine and then the other. Another benefit of fault domains is that network access and data storage are replicated, ensuring these resources are always available."

This is another variation of a question asked earlier in the interview. The unique aspect of this question is that it brings up the personal use of clouds. This indicates that the interviewer is interested in the types of clouds you have been involved with and what your role in these was. You could answer this question by first describing each type of cloud and then discussing your role.

Written by William Swansen on October 26th, 2021

Answer Example

"The three main types of clouds I have been involved with include professional, personal, and performance. The professional cloud is the one most organizations are familiar with. This usually involves utilizing resources in commercial environments such as AWS or Microsoft Azure to supplement or replace their organization's current IT environment. A personal cloud may be an individual's website or an off-site computing environment. An example of this is Google, which can provide a range of services, including computing, applications, and data storage. The third type of cloud environment is performance-based. This enables organizations to reduce the time it takes to access resources by placing them closer to the users, increasing the bandwidth, and providing resources which the organization itself can't provision."

Written by William Swansen on October 26th, 2021

8.   What are some other major cloud database providers you have worked with, and why do you prefer their products?

How to Answer

An interviewer will ask this type of question to determine if you are familiar with some of the technologies they currently use or are considering.

10.   Do your cloud computing architectures plan for spikes in network traffic, and if so, how?

How to Answer

Every cloud engineer knows that there are peaks and troughs of network activity. Many engineers will architect systems to accommodate the peaks or spikes in network traffic. While this ensures that the resources will be available to every user who needs them, it also results in higher infrastructure and maintenance costs for the organization. A better strategy is to architect an IT environment to accommodate both average traffic loads as well as occasional and infrequent peak traffic. Cloud computing contributes to accommodating the traffic by providing the availability of standby systems. Your answer to the interviewer's question should demonstrate your knowledge of this, as well as the strategies you employ to accommodate spikes in traffic while maintaining a reasonable IT operating budget.

Written by William Swansen on October 26th, 2021

Answer Example

"Every competent cloud engineer understands that network traffic is not constant. Peaks occur due to increased user activity which may be seasonal, a reaction to certain events, or a result of known issues such as end-of-year activities. Planning for both the known and unknown spikes in network traffic requires architecting a system that can handle higher than normal activity. This could involve having access to standby resources, using strategies such as IaaS, PaaS, and SaaS, and other provisions which can be brought online as network activity increases or spikes. I employ all of these strategies to ensure that the IT resources are available and that the operating budget is maintained at targeted levels."

11.   What steps do you take to engineer your cloud computing infrastructure to maximize uptime?

How to Answer

Uptime is one of the more critical elements of any IT infrastructure. If the users can't access the IT resources, then they are useless. As a cloud engineer, you should have a portfolio of skills and techniques to maintain access to the organization's IT resources and ensure that they are always available. Strategies include redundancy, active management, backup provisions, and other means of ensuring that IT resources are always available.

Written by William Swansen on October 26th, 2021

Answer Example

"System uptime is something that I focus on constantly in my role as a cloud engineer. When systems go down, not only does it cause issues, but it impacts the entire organization with lost productivity and the additional costs required to restore the system's availability. Measures I take to avoid this include architecting redundancy into the infrastructure, providing real-time monitoring of the environment, having contingency plans in place if a system failure occurs, and making myself available whenever needed to address system downtime. This comprehensive strategy has resulted in uptime metrics of greater than five-nines throughout my career."

12.   Can you describe a multi-cloud strategy you've applied in one of your previous positions?

How to Answer

This is an example of a follow-up question to another question the interviewer may have asked earlier in the interview. Interviewers will ask follow-up questions either immediately after a related question or later in the interview. The purpose of a follow-up question is to collect more information, explore the topic in more detail, or correlate your answers to ensure you are consistent throughout the interview. You should be prepared for follow-up questions at all times during the interview for a cloud engineer's role.

Written by William Swansen on October 26th, 2021

Answer Example

"In my most recent job, I applied in multi-cloud strategy, using several cloud service providers to deliver the computing resources the organization needed. I worked with Azure and AWS to create independent but connected cloud computing environments. Initially, I did this to create redundant environments to prevent downtime. However, it became apparent that each provider offered a portfolio of specialized services that would optimize the operation of different segments of our infrastructure. Therefore, I relocated some of our computing services between the two providers to accomplish this."

13.   What are the steps used to design and deploy a cloud architecture?

How to Answer

By asking this question, the interviewer indicates that they are interested in deploying a cloud architecture but may not have the experience or resources needed to do this. This is probably one of the main reasons they are looking to hire a cloud engineer. This may have even been disclosed in the job description. When interviewing for this role, a good strategy may be to create a pro forma plan to develop a cloud architecture and present it to the interviewer. This would be especially effective if this requirement was mentioned in the job description.

Written by William Swansen on October 26th, 2021

Answer Example

"When I am designing and deploying a cloud architecture, I use three distinct steps in the process. The first is to develop a reference architecture. This is based on how the cloud resources will be used and what services the users would like to access. The next step was to create a technical architecture. This involves all the hardware, software, network, and applications required to provision the reference architecture. The final step is the deployment operation architecture. This describes how the technical architecture will be deployed and what resources will be required to keep it functioning. These resources involve the cloud provider's services and those managed by the organization's IT personnel."

14.   How are data centers deployed or transitioned to the cloud?

How to Answer

This question seeks to understand your knowledge of how data centers can move from their on-premise location into the cloud. This is a complex operation that involves many steps and the coordination of a great number of resources. The timing is also critical so that the move does not impact an organization's operations or result in any data loss. Knowing how to perform this operation is a key qualification for a cloud engineer.

Written by William Swansen on October 26th, 2021

Answer Example

"Transitioning an organization's IT resources into the cloud can take many forms. It can be a complete move of the data center, a partial move, or simply replicating the resources at a cloud hosting site. Each of these requires a great deal of planning and coordination. The objective is to relocate the resources into the cloud without any disruption in the organization's operations or any data loss. When planning a data center move, I pay close attention to which resources will be transitioned, and how the move will be executed in order to maintain continuity of operations. As well as, ensuring all the data is backed up to prevent losses, and executing the move when the company's activity is at its lowest, which is typically on a weekend or during a holiday. I also provision for contingencies just in case issues crop up."

15.   Can you discuss the major differences between the cloud and a traditional data center?

How to Answer

As the interview progresses, the interviewer may switch between the different types of questions. These can include general, technical, operational, behavioral, and situational questions. Being familiar with each type of question and knowing how to respond to them is critical to a successful interview. This is a general question, so your response should be general in nature. Keep your answer brief and to the point to include the interviewer to move on to a new question or explore this topic in more detail by asking a follow-up question.

Written by William Swansen on October 26th, 2021

Answer Example

"There's very little difference between a cloud environment and a traditional data center from an infrastructure standpoint. The key differences are how the resources are accessed and who is responsible for managing them. In a traditional data center, the organization is responsible for all aspects of the IT environment. These include acquiring the resources, managing them, updating them, and maintaining them. In a cloud environment, the organization purchases the services on an as-needed basis. This reduces their initial investment, allows them to scale up or down as needed, and provides them access to resources they may not be able to afford. The tradeoff between the two environments is that the cloud is often less expensive, whereas the traditional data center provides the organization with more control and better security."
