Cloud Computing

Question 1

What is cloud computing?

Answer 1

The on-demand delivery of IT resources over the internet w/ pay-as-you-go pricing. Instead of owning and maintaining physical data centers and servers, you can access technology services such as computing, power, storage, and databases, on an as-needed basis from a cloud provider like AWS (Amazon Web Services)

Question 2

What are the 3 main types of Cloud Computing Services?

Answer 2

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

Question 3

What is Infrastructure as a Service?(IaaS)

Answer 3

IaaS contains the basic building blocks for cloud IT. It typically provides access to networking features, computers (virtual or on dedicated hardware), and data storage space. IaaS gives you the highest level of flexibility and management control over your IT resources. It is most similar to the existing IT resources with which many IT departments and developers are familiar.

Question 4

What is Platform as a Service (PaaS)?

Answer 4

PaaS removes the need for you to manage underlying infrastructure (usually hardware and operating systems), and allows you to focus on the deployment and management of your applications. This helps you be more efficient as you don’t need to worry about resource procurement, capacity planning, software maintenance, patching, or any of the other undifferentiated heavy lifting involved in running your application.

Question 5

What is Software as a Service (SaaS)?

Answer 5

SaaS provides you with a complete product that is run and managed by the service provider. In most cases, people referring to SaaS are referring to end-user applications (such as web-based email). With a SaaS offering, you don’t have to think about how the service is maintained or how the underlying infrastructure is managed. You only need to think about how you will use that particular software.
