Cloud Computing Interview Questions

Cloud Computing Interview Questions

1) How does cloud computing work?

Cloud computing is a new computer technology that is based on the internet. It is the next-generation technology that utilizes cloud computing to deliver services whenever and wherever the user requires them. It allows you to connect to several servers all over the world.


2) How does cloud computing benefit you?

The following are the key advantages of cloud computing:

Data backup and data storage
Capabilities of a powerful server.
Productivity has increased.
Very economical and time-saving.
SaaS stands for Software as a Service.


3) What is a cloud, exactly?

A cloud is a collection of networks, hardware, services, storage, and interfaces that enable computing as a service to be delivered. It is used by three people:

Cloud service provider for business management.


4) What are the many forms of data used in cloud computing?

Emails, contracts, photos, blogs, and more data kinds exist in cloud computing. As we all know, data is growing at an exponential rate, necessitating the creation of new data kinds to accommodate this growth. If you wish to store video, for example, you'll need a new data type.


5) What are the various levels that make up a cloud architecture?

The following are the various layers that cloud architecture employs:

Cloud Controller (CLC)
SC or Storage Controller NC or Node Controller Walrus Cluster Controller


6) What are the platforms for large-scale cloud computing?

For large-scale cloud computing, the following platforms are used:

Apache Hadoop



7)What are the distinct layers in cloud computing? What is Apache Hadoop MapReduce? Explain how they function.

The cloud computing hierarchy is divided into three tiers.

Infrastructure as a service (IaaS): It offers cloud infrastructure in terms of memory, processor, speed, and other factors.

PaaS (platform as a service) is a cloud application platform for developers.

SaaS (Software as a Service): It gives cloud apps to customers directly without the need for installation.

installing something on the computer These programs are hosted on the cloud.


8) What exactly do you mean when you say "software as a service"?

Cloud computing's Software As A Service (SaaS) layer is crucial. It, like Google, delivers cloud applications. It allows users to save documents to the cloud and create new ones.


9) What does "platform as a service" mean?

It's also a cloud architecture layer. This paradigm is based on infrastructure and includes resources such as computers, storage, and networking. Its job is to virtualize the infrastructure layer completely, making it appear as a single server and invisible to the outside world.


10) What does "on-demand" mean? How does cloud computing supply it?

Cloud computing allows users to access virtualized IT resources on demand. It is accessible to the subscriber. It provides adjustable resources via a shared pool. Networks, servers, storage, applications, and services are all part of the shared pool.


11) What platforms are available for large-scale cloud computing?

Large-scale cloud platforms include Apache Hadoop and MapReduce. 


12) What are the various deployment models in cloud computing?

The following are the many cloud computing deployment models:

Public cloud Private cloud

Cloud hybrid


13) What exactly is a private cloud?

Private clouds are utilized to protect strategic activities and other data. It is a fully working platform that may be owned, operated, and confined to a single organization or industry. Because of security concerns, most businesses have switched to private clouds. A hosting company employs the utilization of a virtual private cloud.


14) What exactly is the public cloud?

The public clouds are available for everyone to use and deploy. Google and Amazon, for example. The focus of public clouds is on

a few levels, such as cloud applications, infrastructure providers, and platform providers

15) What do hybrid clouds entail?

Hybrid clouds are made up of both public and private clouds. It is recommended above both clouds because it uses the most robust method to cloud architecture implementation. It combines the best of both worlds' functionalities and characteristics. It enables businesses to construct their cloud and delegate control to another party.


16) What is the distinction between cloud and mobile computing?

The concepts of mobile computing and cloud computing are similar. The concept of cloud computing is used in mobile computing. While in mobile computing, applications operate on a remote server and cloud computing provides users with the data they demand. 


17) What is the distinction between elasticity and scalability?

Scalability is a feature of cloud computing that allows it to accommodate increasing workloads by increasing resource capacity proportionally. The architecture makes use of scalability to deliver on-demand resources if traffic increases the need. Elasticity, on the other hand, is a property that allows for the dynamic commissioning and decommissioning of enormous amounts of resource capacity. It is determined by the rate at which resources are made available and how they are used.


18) What are the advantages of cloud computing in terms of security?

Cloud computing is utilized in identity management since it authorizes the application service.

It permits people so they can manage their data.

the entry into the cloud environment of another user


19) What is utility computing used for?

Utility computing is a plug-in that is administered by an organization that determines what kind of cloud services must be delivered. It allows people to pay for only what they use.


20) In cloud computing, what is "EUCALYPTUS"? What is its purpose?

Elastic Utility Computing Architecture For Linking Your Program To Useful Systems is an acronym. It is an open-source cloud computing software architecture that is used to construct cloud computing clusters. It offers public, private, and hybrid cloud services. It allows users to turn their own data center into a private cloud and use its features.


21) Describe the role of cloud computing system integrators.

The strategy of a difficult procedure required to design a cloud platform is provided by a system integrator. Because the integrator has all of the expertise in data center creation, it develops a more realistic hybrid and private cloud network.


22) What are the databases for open source cloud computing platforms?

Open source cloud computing platform databases include MongoDB, CouchDB, and LucidDB.


23) Can you give an example of a huge cloud provider or database?


simple by Amazon

SQL in the cloud
