Question 1

What is cloud computing?

Answer 1

Cloud computing is the delivery of computing services over the internet (the cloud), including servers, storage, databases, networking, software, and analytics.

Question 2

Name the three main cloud service models.

Answer 2

1. Infrastructure as a Service (IaaS)
2. Platform as a Service (PaaS)
3. Software as a Service (SaaS)

Question 3

What is IaaS?

Answer 3

IaaS (Infrastructure as a Service) provides virtualized computing resources over the internet, such as virtual machines, storage, and networks.

Question 4

What is PaaS?

Answer 4

PaaS (Platform as a Service) provides a platform for application development, including infrastructure, but without the need to manage the underlying infrastructure.

Question 5

What is SaaS?

Answer 5

SaaS (Software as a Service) delivers software applications over the internet, with the provider managing the underlying infrastructure and software.

Question 6

What are the benefits of cloud computing?

Answer 6

Benefits include: high availability, scalability, elasticity, cost-efficiency, disaster recovery, and reduced management overhead.

Question 7

What is the shared responsibility model in cloud computing?

Answer 7

In the shared responsibility model, the cloud provider manages the infrastructure, while the customer manages the data, identity, and application security.

Question 8

What is scalability in cloud computing?

Answer 8

Scalability allows resources to increase or decrease according to demand.

Question 9

What is elasticity in cloud computing?

Answer 9

Elasticity automatically adds or removes resources to accommodate changing workloads.

Question 10

What is a hybrid cloud?

Answer 10

A hybrid cloud combines public and private clouds to allow data and applications to be shared between them.

Question 11

Define cloud computing.

Answer 11

Cloud computing is the delivery of computing services over the internet, including storage, databases, servers, networking, software, and analytics.

Question 12

What are the three main types of cloud computing models?

Answer 12

Public, Private, and Hybrid cloud models.

Question 13

What are the main cloud service models?

Answer 13

IaaS (Infrastructure as a Service), PaaS (Platform as a Service), and SaaS (Software as a Service).

Question 14

What is Infrastructure as a Service (IaaS)?

Answer 14

IaaS provides virtualized computing resources over the internet, such as virtual machines, networks, and storage.

Question 15

What is Platform as a Service (PaaS)?

Answer 15

PaaS provides a platform that allows customers to develop, run, and manage applications without dealing with infrastructure.

Question 16

What is Software as a Service (SaaS)?

Answer 16

SaaS delivers software applications over the internet, with the provider managing the underlying infrastructure.

Question 17

What is the key benefit of cloud scalability?

Answer 17

Cloud scalability allows resources to grow or shrink based on demand.

Question 18

What is elasticity in cloud computing?

Answer 18

Elasticity refers to the ability to automatically increase or decrease computing resources as needed.

Question 19

What are the benefits of cloud computing?

Answer 19

High availability, scalability, elasticity, cost-efficiency, disaster recovery, and reduced management overhead.

Question 20

What is the shared responsibility model?

Answer 20

A security model where cloud providers manage infrastructure, and customers manage their data, identity, and application security.

Question 21

What are the advantages of using cloud services?

Answer 21

Reduced capital expenditure, scalability, flexibility, faster time to market, and reduced operational costs.

Question 22

What are the three main deployment models in cloud computing?

Answer 22

Public, Private, and Hybrid cloud.

Question 23

What is the key difference between IaaS and PaaS?

Answer 23

IaaS provides raw infrastructure resources, while PaaS includes infrastructure and a platform for app development.
