Information Systems Chapter 4 Review Questions 9-15 Critical Thinking Questions 1 – 2 (Page 179)

Cloud computing is one of the fastest growing segment of Information technology today. In simple words cloud computing means storing and accessing data and programs over the internet instead on the computer's hard drive which can be accessed from any part of the world if the individual are connected to the internet or a network connection is available 24/7. A simple example of cloud computing is g-mail. With the connection of internet through any medium we can send and receive emails.

A RESTful API defines a set of functions that developers can use to perform requests and receive responses via HTTP protocol, such as GET and POST. Because RESTful APIs use HTTP as a transport, they can be used by practically any programming language and are easy to test. It’s a requirement of a RESTful API that the client and server are loosely coupled and independent of each other, allowing

Cloud Computing: Cloud computing is when you can store files onto an online server which you can access from various different devices.

Cloud computing refers to a computing environment where software and storage are provided as an internet service and accessed with a web browser.

Adding to that updating the hardware drive helps to get the most of the hardware which may offers a new features or improvement in the hardware capabilities.

An Online Applications (also known a web application) is an type of application that is accessed by a user through the internet or a network. A Web Application also may mean a computer software application that is encoded in a web-browser supported program. For example java script is one of these. Most Online applications are interactive and user friendly.

The nature of promises is that they remain immune to changing circumstances. Therefore creating an API for a software or data resource would seem paradoxical given that the nature of software and data is that they are improved upon and changed constantly. In order for an organization to evolve its resources and to keep promises to external developers, its APIs need to be correctly maintained. Changes that break API functionality require the API to be versioned. Non-breaking changes avoid the need for new versions.

Cloud computing is an internet based computing which provides various applications and services like storage, servers, infrastructure, networking with low cost, on-demand self service, pay as you go model, location independent resource pooling, reasonable price , rapid elasticity etc. Cloud computing is one way to increase the capacity add capabilities without investing in new infrastructures like computer hardware involves storage memory, licensing for new software, training for a person and in a dynamic way.

b. Software as a service or the SaaS : Cloud platforms that allow the clients to access several software modules and databases that are installed on the platform itself, are considered to use the SaaS model (He, Fan and Li 2013).

(3) Web Services in the Cloud - instead of delivering full applications, this service allows users to access APIs for added functionality.

11. (TCO D) What is cloud computing and how do you think its developments could impact businesses?

ERP, which is an abbreviation for Enterprise Resource Planning, is principally an integration of business management practices and modern technology. Information Technology (IT) integrates with the core business processes of a corporate house to streamline and accomplish specific business objectives.

C) hosting and managing access to software applications delivered over the Internet to clients on a subscription basis.

is used as a means to represent web services for the following important benets:

c) Software-as-a-Service (SaaS): Software as a Service (SaaS) is a software distribution model in which applications are hosted by a vendor or service provider and made available to customers over a network, typically the Internet.
