Basic Cloud computing concepts

Question 1

What is cloud computing?

Answer 1

The delivery of computing services, such as servers, storage, databases, and networking, over the Internet to provide faster innovation, flexible resources, and economies of scale.

Question 2

How does cloud computing lower operating costs?

Answer 2

By only paying for the cloud services used, rather than the capital expense of buying hardware and setting up on-site datacenters.

Question 3

Why do organizations move to the cloud?

Answer 3

For cost savings, improved speed and scalability, increased productivity, better performance, reliability, and improved security.

Question 4

What is the advantage of cloud computing’s self-service and on-demand nature?

Answer 4

It allows for vast amounts of computing resources to be provisioned quickly, giving businesses a lot of flexibility and taking the pressure off capacity planning

Question 5

What does “elastically scaling” mean in cloud computing?

Answer 5

Delivering the right amount of IT resources, such as computing power and storage, at the right time and from the right location.

Question 6

How does cloud computing improve productivity?

Answer 6

By removing the need for time-consuming IT management tasks, allowing IT teams to focus on more important business goals.

Question 7

How does cloud computing improve performance?

Answer 7

By running on a worldwide network of secure datacenters that are regularly upgraded to the latest generation of efficient computing hardware, reducing network latency and offering greater economies of scale.

Question 8

How does cloud computing improve performance?

Answer 8

By running on a worldwide network of secure datacenters that are regularly upgraded to the latest generation of efficient computing hardware, reducing network latency and offering greater economies of scale.

Question 9

How does cloud computing improve reliability?

Answer 9

By making data backup, disaster recovery, and business continuity easier and less expensive through data mirroring at multiple redundant sites on the cloud provider’s network.

Question 10

How does cloud computing improve security?

Answer 10

By offering a broad set of policies, technologies, and controls that strengthen the overall security posture, protecting data, apps, and infrastructure from potential threats.

Question 11

What is the main advantage of using cloud computing?

Answer 11

Cost savings, improved speed and scalability, increased productivity, better performance, reliability, and improved security.

Question 12

What is the biggest difference between cloud computing and traditional IT resources?

Answer 12

Traditional IT resources required buying hardware and software, setting up and running on-site datacenters, and paying for electricity and IT experts. Cloud computing eliminates these expenses and provides flexible and on-demand resources.

Question 13

What are the benefits of cloud computing services?

Answer 13

Faster innovation, flexible resources, and economies of scale.

Question 14

What is the advantage of cloud computing over traditional on-site datacenters?

Answer 14

Cloud computing eliminates the need for hardware setup, software patching, and other time-consuming IT management tasks, allowing IT teams to focus on more important business goals.

Question 15

What is the advantage of cloud computing over a single corporate datacenter?

Answer 15

Reduced network latency for applications and greater economies of scale.

Question 16

What is the main advantage of data backup, disaster recovery, and business continuity in cloud computing?

Answer 16

It is easier and less expensive.

Question 17

What is the main advantage of security in cloud computing?

Answer 17

Cloud providers offer a broad set of policies, technologies, and controls that strengthen the overall security posture.

Question 18

What is the shared responsibility model in cloud computing?

Answer 18

The shared responsibility model in cloud computing refers to the division of responsibilities between the cloud provider and the customer in terms of security tasks and workloads.

Question 19

What are the different types of cloud deployment?

Answer 19

The different types of cloud deployment are Software as a Service (SaaS), Platform as a Service (PaaS), Infrastructure as a Service (IaaS), and on-premises datacenter.

Question 20

In which type of deployment do customers retain the most responsibilities?

Answer 20

In an on-premises datacenter, customers retain the most responsibilities, as they own the entire stack.

Question 21

What responsibilities are always retained by the customer, regardless of the type of deployment?

Answer 21

The responsibilities retained by the customer regardless of the type of deployment are data, endpoints, account, and access manage

Question 22

In a SaaS deployment, which party is responsible for protecting the security of the data?

Answer 22

In a SaaS deployment, the customer is responsible for protecting the security of the data.

Question 23

In a PaaS deployment, who is responsible for managing and maintaining the underlying infrastructure?

Answer 23

In a PaaS deployment, the cloud provider is responsible for managing and maintaining the underlying infrastructure.

Question 24

In an IaaS deployment, who is responsible for managing and maintaining the operating systems and middleware?

Answer 24

In an IaaS deployment, the customer is responsible for managing and maintaining the operating systems and middleware.
