      1st 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

      1st 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."

    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

      1st 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."

    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.

    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.
