If you have to use the cloud for any aspect of your business, you might have to answer these questions during an interview in order to be hired or retained as an employee <a href="https://thinkcloudly.com/" style="text-decoration:none;"><span style="font-size:11pt;font-family:Arial;color:#1155cc;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:underline;-webkit-text-decoration-skip:none;text-decoration-skip-ink:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;"><img src="https://lh3.googleusercontent.com/UQeVkhlGmIXQnmTmm5RurTeaK_dKirNauQErPoCJp5so4w5pKjapjOq1ymmA3hWE-09v6K_Ke8VsfKElr0M9p0RD7cWMbJhS9Q7463wprR5F1QhK1pNYjm98OHHqy7OLRaO_dNrZ4zCkQiY2xPXDNWSEenE7vISitI8fcAeg5iMAB2EnDDBqE7yQoQ" width="475" height="249"></a> <h2 dir="ltr" style="line-height:1.38;text-align: justify;margin-top:18pt;margin-bottom:6pt;"><span style="font-size:16pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">How do you define cloud computing?</h2> <span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">Cloud computing is a term used to describe the delivery of various services, such as storage, software applications and virtual desktops, over the internet or other network connection. <a href="https://thinkcloudly.com/aws-cloud-practitioner-2022-salary-skills/" style="text-decoration:none;"><span style="font-size:11pt;font-family:Arial;color:#1155cc;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:underline;-webkit-text-decoration-skip:none;text-decoration-skip-ink:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">Cloud computing skills</a><span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;"> are in high demand due to the expanding popularity of this type of technology. Cloud computing allows employees or businesses access and use these services on demand without having to purchase their own hardware or software. This has led companies such as Google and Amazon Web Services into investing in cloud computing. <h2 dir="ltr" style="line-height:1.38;text-align: justify;margin-top:18pt;margin-bottom:6pt;"><span style="font-size:16pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">Explain the main features and benefits of cloud computing</h2> <a href="https://thinkcloudly.com/top-20-cloud-computing-interview-questions/" style="text-decoration:none;"><span style="font-size:11pt;font-family:Arial;color:#1155cc;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:underline;-webkit-text-decoration-skip:none;text-decoration-skip-ink:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">Cloud computing Interview questions</a><span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;"> is a term that is used to describe the hosting of applications and services on a network of remote servers, accessed via the internet. Cloud computing can offer many benefits including easier data access, lower costs and more flexibility. If you are interested in cloud computing skills for your next career move, here are some of the top features and benefits you should be aware of:  <span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">-Clouds offer easier data access because it can be anywhere at any time. This means that companies can do business without having their own IT resources in-house which simplifies things like disaster recovery and scalability  <span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">-Clouds also offer lower costs because they eliminate an organization's need for capital intensive IT infrastructure. <h2 dir="ltr" style="line-height:1.38;text-align: justify;margin-top:18pt;margin-bottom:6pt;"><span style="font-size:16pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">Differentiate between public, private, & hybrid clouds</h2> <span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">A public cloud is one that’s typically offered by a third party and the owner of the data can be unknown. With public clouds, you have no control over who has access to your data. A private cloud is one that’s owned and managed by an organization, meaning you know who has access and it’s more secure than a public cloud. <span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;"> A hybrid cloud is a combination of both, where some of your data may be stored with a third party but there are also private aspects for security purposes. It's important to note that not all clouds use the same technologies; in fact, they all use different levels of abstraction and interoperability standards. That's why it's essential for cloud computing skills!  <span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">A cloud solution is any service or application which offers various forms of storage (typically in remote servers), virtualized processing power, virtualized bandwidth provisioning, etc., on demand from a web-browser or a mobile device such as smartphone or tablet. <h2 dir="ltr" style="line-height:1.38;text-align: justify;margin-top:18pt;margin-bottom:6pt;"><span style="font-size:16pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">List common cloud deployment models</h2> <span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">There are a number of common deployment models for cloud computing. The most popular models are public, private, and hybrid clouds. Private clouds are typically deployed by large corporations that want to use the cloud for their own purposes. Public clouds are typically made available to any organization that wants them on a pay-as-you-go basis. In contrast, hybrid clouds combine features from both public and private deployments with the goal of offering organizations the best of both worlds. <span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">2. What is a Virtual Machine? A <a href="https://thinkcloudly.com/virtual-machine-scale-sets-quiz/" style="text-decoration:none;"><span style="font-size:11pt;font-family:Arial;color:#1155cc;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:underline;-webkit-text-decoration-skip:none;text-decoration-skip-ink:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">virtual machine</a><span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;"> (VM) is an environment in which you can install an operating system (OS). VMs let you create copies of OSs in order to test software on different configurations or run multiple operating systems simultaneously. <h2 dir="ltr" style="line-height:1.38;text-align: justify;margin-top:18pt;margin-bottom:6pt;"><span style="font-size:16pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">Explain server virtualization in relation to cloud computing</h2> <span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">Server virtualization is a process of running multiple operating systems on one physical machine. A hypervisor is the software that enables this and allocates computing resources such as CPU, RAM and disk space among the various guest operating systems. Hypervisors are also known as virtual machine monitors (VMM).  <span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">The approach of using a single physical server to run multiple operating systems can be considered as an early form of cloud computing, which is now possible with the availability of public cloud services. The fundamental principle behind server virtualization is abstraction. Guest operating systems installed on top of a VM believe they have exclusive control over the underlying hardware, but in reality all VMs share access to it in a multitenant fashion.  <span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">All VMs are isolated from each other, so no direct interaction or data sharing between them is possible. However there might be some side effects like higher latency because they share access to the same set of hardware resources and some performance degradation due to increased number of contexts switching during context switches when accessing memory pages. It's important for you to know what technologies related to cloud computing you're going up against if you're interviewing for any position involving cloud technologies because this would help determine your career path <h2 dir="ltr" style="line-height:1.38;text-align: justify;margin-top:18pt;margin-bottom:6pt;"><span style="font-size:16pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">Give an example of how you would define and develop a cloud computing solution</h2> <span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">A cloud computing solution is a form of IT infrastructure that provides on-demand access to pooled resources, such as processing power, data storage and applications, from a range of sources.  <span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:700;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">The cloud solution is composed of five components:  <ul style="margin-top:0;margin-bottom:0;padding-inline-start:48px;"> <li aria-level="1" dir="ltr"

major benefits of this type of infrastructure are the scalability it offers businesses, the ability for organisations to utilise existing infrastructure more efficiently and the flexibility it provides in terms of deployment. <h2 dir="ltr" style="line-height:1.38;text-align: justify;margin-top:18pt;margin-bottom:6pt;"><span style="font-size:16pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">Compare and contrast platform as a service (PaaS) with software as a service (SaaS)</h2> <span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">Platform as a service, or PaaS, is a type of cloud computing that provides all the necessary tools and frameworks for programmers to build applications without needing any in-depth knowledge of servers. It is similar to software as a service (SaaS) in that it offers hosted applications, but there are some key differences.  <span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">Software as a service is based on the idea that programmers should not have any advanced knowledge of their servers and infrastructure, while platform as a service allows programmers to have more control over the deployment process. This can come with pros and cons: while PaaS may be more flexible, there are risks associated with it because you have less oversight of your system's stability. <h2 dir="ltr" style="line-height:1.38;text-align: justify;margin-top:18pt;margin-bottom:6pt;"><span style="font-size:16pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">Which type of storage is used by public clouds, private clouds and hybrid clouds?</h2> <span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">Public clouds, private clouds and hybrid clouds all use storage. However, the type of storage used depends on the specific environment. Private cloud environments typically use a hybrid of different types of storage, such as SAN or NAS. Public cloud environments often use a mix of higher-end SAS disks and SATA disks. <span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;"> Hybrid cloud environments might also be composed of a mix of higher-end SAS disks, SATA disks and SSDs or lower-end SAS and SATA disks. <span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;"> 2. What is Application Programming Interface? APIs are programming interfaces that can connect software components in new ways to build more advanced programs. For example, an API for accessing Gmail could give developers access to Gmail's data so they could send messages from Gmail in their own app without having access to any of Gmail's internal code.  <span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">3. What is Processing? Processing is the conversion of raw data into meaningful information for humans or computers to read and understand.  <span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">4) Why do some people say that cloud computing has changed our lives? <span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:700;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;"> There are many benefits associated with adopting cloud computing:  <span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;"> 1) no upfront investments; <span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;"> 2) global scalability;  <span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;"> 3) increased security; <span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;"> 4) flexible scaling;  <span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;"> 5) easier management;  <span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;"> 6) reduced costs, etc. <h2 dir="ltr" style="line-height:1.38;text-align: justify;margin-top:18pt;margin-bottom:6pt;"><span style="font-size:16pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">Final Thought</h2> <span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">Cloud computing is a hot topic in the tech world these days, so it's no wonder that you're expected to know a thing or two about it. Your interviewer will likely ask you questions like What is cloud computing? and How does cloud computing work? Some of the other interview questions they may ask are listed below. The more you prepare, the better off you'll be!  <span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">Study up on your IT terminology, along with any basic programming skills and what the different types of clouds are before going into your interview. Ask someone who works with this type of technology for some advice on what to expect in an interview like this one. And make sure you practice giving an answer before your meeting. It'll make all the difference in how well prepared you are when it comes time to talk to your interviewer! ``` ```
