QFLES is listing some Essential Cloud Computing Interview Questions and Answers for Freshers and mid level of Experienced Professionals prepared by Industry Experts. All answers for these Cloud Computing interview questions are given based on standard documents and tried to explain in simple and easiest way.
These are the latest cloud computing questions which may be asked in your interview.
1. What is Cloud? Explain it.
Cloud is a just a storage or retrieval of information over the Internet. In simple terms Cloud refers the servers, databases and softwares running on these servers, which can be accessed over Internet. Data centers are used as container for these servers. Companies and Users does not need to worry about to manage their servers themselves.
2. What is Cloud Computing?
Cloud Computing provides the availability of computing resources including software, servers, networking, databases, storage on demand without active management by users. In cloud computing you pay only for your usage that offers low operating cost , running you infrastructure efficiently. Availability of computing resources offers large scalability, flexibility and other benefits.
3. Explain the benefits of Cloud Computing?
Cloud computing is the on-demand availability of computing resources with full flexibility, scalability and other benefits as below.
4. Explain the components of Cloud Computing Architecture?
There is the requirement of many components and sub components in cloud computing architecture as below.
5. What are the different types of Cloud Deployment?
Every organization or user required different types of cloud services like cloud models, types and services. Before choosing the first cloud You should determine the Architecture of cloud or type of cloud deployment for the implementation of your services. Cloud services can be deployed in 4 different ways.
6. Explain the Public Cloud deployment model.
Public Cloud services are operated by external vendors called cloud providers which provide you servers, storages, computing resources. Microsoft Azure is the example of Public Cloud that is managed and operated by Microsoft. Public clouds are shared by multiple users or organizations. Multiple companies can use same virtual machines or servers. Multiple tenants use same server it's called 'Multitenancy' situation.
7. Explain the Private Cloud deployment model.
Private Cloud refers to servers, data centers, computing resources dedicated to single organization. In private cloud service and resources are maintained over a private Network. Physical location of Private cloud can be company's own data center. Third party providers can also setup the private cloud for organizations.
8. Explain the Hybrid Cloud deployment model.
Hybrid Cloud is the combination of Public cloud and private cloud. Organizations use public cloud as backup for private clouds or public cloud for some other service and private cloud for some different services. Hybrid cloud provide more deployment options, better flexibility and optimized infrastructure, compliance and security.
9. Explain the Multi Cloud deployment model.
Multi cloud refers to use multiple public clouds means to take computing resources, servers, and services from multiple public cloud providers.
10. What are the characteristics of cloud computing?
Cloud Computing offers various services for the enterprises to scale up the business with following characteristics.
11. What are the Cloud Computing Service Models.
Cloud computing services are divided into four categories. Sometimes these are called cloud computing service models or cloud computing stack as name 'stack' suggests these are build on top of one another. Every type has a significant role for your business.
12. Describe the IaaS(Infrastructure as a Service).
Infrastructure as a Service (IaaS) is a most basic category of cloud computing services. In this you pay the rent for IT Infrastructure (including
operating systems, storage, servers, virtual machines, networks etc.) to the cloud provider. It's charged basically on pay-as-you-go basis.

13. Explain the Characteristics and advantage of IaaS (Infrastructure as a Service).
14. Describe the PaaS(Platform as a Service).
Platform as a Service (PaaS) cloud computing service model deliver the computing resources based on demand for developing, testing and managing the system
applications. It makes developers life easier to develop the mobile or web applications as they do not need to worry about setting up and managing the Infrastructure of virtual machines, operating systems, servers,

15. Explain the Characteristics and advantage of PaaS (Platform as a Service).
16. Describe the SaaS(Software as a Service).
Software as a Service (SaaS) is a method for delivering the software applications as a service over the network. Software as a Service is delivered based on demand
and subscription. Cloud service providers are responsible for all maintenances like software updates, patch releases , security and underlying Infrastructure. End Users can access the
application over the Internet using PC, tablets and mobiles.

17. Explain the Characteristics and advantage of SaaS (Software as a Service).
18. Describe the Serverless computing.
Serverless Computing is overlapped with PaaS, It allow organizations to focus on their application development without managing the IT Infrastructure
for servers, storages, networks etc. The cloud provider works for you here as he has the responsibility to manage the Infrastructure, capacity planning and servers for you.
Serverless architecture is highly scalable. It's based on event driven architecture means Resources are utilized only when specific trigger or function occurs.
