Cloud Computing Questions And Answers

How do you define Cloud Computing?

Answer: By utilization of shared resources and infrastructure, the delivery of computing as a service is called Cloud Computing. This service is often rendered via a network.

What are the different kinds of services that Cloud Computing can provide?

Answer: The concept of Cloud Computing can be used to provide computational, data access, storage and software services. These services can be accessed/utilized by the end user over the internet. 

Who is the end user in a Cloud Computing model?

Answer: When we talk about the end user, we are usually referring to the person accessing the cloud from a remote location. Any person/user utilizing the services offered in a cloud as a part of a financial agreement is known as the end user.

How can an end user access the services available on a Cloud?

Answer: There are several ways by which an end user can access services present at a particular cloud. Some of these require the user to plug into the cloud via: Web Browser Cloud based application Mobile applications Business software

Explain Converged Infrastructure, in the context of Cloud Computing?

Answer: When multiple IT components are packaged into a single, user-based solution; the offered package is known as a converged infrastructure. Such an infrastructure may include services like data storage, infrastructure management, orchestration, servers, networking equipment and automation, all bundled into one optimized solution for the end user. 

What are the three fundamental models of Cloud Computing?

Answer: The three fundamental models of Cloud computing include: Infrastructure as a service (IaaS) Platform as a service (PaaS) Software as a service (SaaS)

Describe PaaS (Platform as a Service).

Answer: PaaS (Platform as a service) is a cloud model in which computingplatform is offered as a service rather than an equipment. Thismeans that an OS (Operating system), Database, languageexecution environment or/and a web server is offered over anetwork environment (Typically, the internet).

Describe SaaS (Software as a Service).

Answer: SaaS (Software as a service) is a cloud model in which software are remotely offered as a service. This means that rather than installing a typical software onto your system, you can access it and use it using a web browser or a cloud based application.

Describe IaaS (Infrastructure as a Service).

Answer: IaaS (Infrastructure as a service) is a cloud model in which computer itself is delivered as a service. This means that Cloud service providers can offer you virtual machines, networks, firewalls and raw storage blocks. IaaS providers usually bill the end user based on utility computing basis (amount of resources utilized).
