1 INFORMATION MANAGEMENT & CLOUD COMPUTING What is Cloud Computing? Types of Cloud Computing How this technology has shaped Information Management 1

2 Introduction The advent of cloud computing has generated a lot of interest among individuals and cooperate organizations. Knowingly or unknowingly, most people use cloud services daily (Rawal, 2011). 2

3 A key notion with CC is Ubiquity of access 3

4 What is Cloud Computing? (1) Cloud computing is described as a computing environment where software applications, computing hardware and other resources are provisioned to authorized users via a network instead of these resources residing on the local devices and location of users. With a network connection on a computer or a smart device, users can access resources on their cloud platforms without any other connection to the hardware that holds the resources (Gruman, 2008). 4

5 What is Cloud Computing? (2) Cloud computing has opened a new phase in the technological sphere where technological products are now rendered as services. This now allows technological products to be repackaged as services to meet the needs of customers. 5

6 Types of Cloud Computing service models The types of service models that have emerged under the cloud computing technology are: Software-as-a-Service (SaaS) Platform-as-a-Service (PaaS) Infrastructure-as- a-service (IaaS) Cloud computing services can be Private, Public or Hybrid. 6

7 Software-as-a-Service (SaaS) Under this service model, cloud computing applications residing on the cloud infrastructure of the service providers are delivered to the user through web interfaces and programs (Mell & Grance, 2011). E.g. Microsoft Word Online and Google Doc. These are word processing applications which are offered as a service on the internet. The software therefore do not reside on the individual device of the user. 7

11 Platform-as-a-Service (PaaS) - 1 PaaS is a type of cloud service model which is described as an upgrade of the SaaS model which offers users a platform to build and run application through a programming interface provided and supported by the cloud service provider (Birk, 2011). PaaS is analogous to SaaS except that, rather than being software delivered over the web, it is a platform for the creation of software, delivered over the web. 11

12 Platform-as-a-Service (PaaS) - 2 Set of tools and services designed to make coding and deploying those applications quick and efficient. Allow users to create their own applications using tools and language from the platform service provider. 12

13 Platform-as-a-Service (PaaS) - 3 For instance, a programmer that needs to build an application that requires a high speed processing Server can sign up for Platform as a Service model rather than spending huge amounts in purchasing servers and operating Systems for the application. E.g. of Platform as a Service models are Google s App-Engine, Microsoft Windows Azure 13

14 Infrastructure-as- a-service (IaaS) In IaaS model, the cloud Service Providers supply a range of virtual infrastructure, such as virtual servers, networks, storage and other fundamental computing resources to customers which enable them deploy and run their own operating system, applications, upload or download software or files into the cloud (Mouratidisa et al., 2013). 14

15 Infrastructure-as- a-service (IaaS) Allows users to run any applications they please on the cloud hardware of their own choice. IaaS is the hardware and software that powers it all, servers storage networks operating systems 15

16 Information Management (IM) & Cloud Computing (CC) The introduction of this technology has affected the way information professionals and even non-information professionals handle information. For the purposes of this class as introductory focus will be on how CC has affected the following areas of IM; Information processing Information Storage Information Sharing 16

17 CC and Information Processing Information processing is about data manipulation to get desired results. In the Digital era this is often aided by a computer software, such as word processor, spread sheet, SPSS, etc. CC creates the opportunity for these data processing software to be accessed and used on multiple devices without necessarily installing them on each device (i.e. SaaS). 17

18 CC and Information Storage & Access A very crucial aspect of IM is information storage and retrieval. Cloud based storage services such as Google Drive TM and Dropbox TM has brought about new phase in information storage and retrieval. (i.e. IaaS) i.e. Information is now stored and accessed from multiple locations, as oppose to the traditional storage and retrieval systems which were confined to specific locations or computer hard drives. 18

19 CC and Information/Data Sharing Collaboration and team work has become inevitable in todays cooperate world. The complexity of today s working environment require teamwork. Where members on a team or project may be in different geographical areas. CC provides an avenue for data sharing and collaboration which defies geographical boundaries. E.g. (SaaS), OneDrive (IaaS), Github (PaaS) 19

20 Conclusion Cloud computing enables individuals and organisations to access a wealth of hardware and software capabilities over the Internet (Spirit Data Capture, 2016). It reduces the need for a large capital outlay on IT investments. 20
