SYSTEM ANALYSIS AND DESIGN3IntroductionIn the past, setting up multiple data centres was the only way the accessibility of data resourcesin an organization’s ICT environment. This outcome increased the overall cost of operations asthe data centres were determined by the size and number of users or branches. Furthermore, theimplementation of information systems was defined by a challenging process that requiredconstant and continuous replication of its defining elements on all the data centres of a givenorganization. Now, fast track to today and these limitations or challenges have been eliminatedby the growth of cloud computing where multiple resources are hosted online and are accessedwhen needed[ CITATION Kim09 \l 1033 ]. A similar objective is held by Headspace, a medicalorganization that deals with a lot of information owing to its treatment procedures of mentalillnesses. In essence, a cloud solution is being sorted out as an alternative to meet the needs ofthe IT resources[ CITATION MuH11 \l 1033 ]. This report highlights the elements of cloudcomputing where its defining components are investigated. Furthermore, the report analyses thestructure of the system including its development procedure.System’s non-functional requirementsA system’s performance is determined by a wide range of factors, most of which are notnecessarily inclined to the functional elements. In this case, the functional requirements willrepresent the factors that determine the system’s operations. On the other hand, the non-functional requirements are the abstract elements that define the processes of achieving the saidoperations[ CITATION Als16 \l 1033 ]. Furthermore, these elements are determined by the user’spreferences and their interactions with the system. Because of this outcome, non-functionalrequirements are measured using subjective factors such as the system’s behaviour or userexperience.
SYSTEM ANALYSIS AND DESIGN4System qualitiesThese are the defining attributes of a system, for instance, Google, the search engine, is widelyused because of its availability and simplicity[ CITATION Sin12 \l 1033 ]. These are the focuselements in this section. Therefore, the system at hand should have the following qualities:Widely available – to enhance this performance and reliability, the user must have aconstant interaction with the system, this outcome may be facilitated by the cloudresources.Content integrity - a security feature that ensures the data and resource used are nottampered with, this can be met using a variety of security features such as authenticationand encryption.Supportability and maintainability – an allowance for system support in case faults ordamages happen. Moreover, there should be a management structure to maintain theoverall functionalities[ CITATION Dor05 \l 1033 ].System interfaceConsider the various aspects of an information system such as storage, processing andpresentation. These functional elements interact with one another to give the functionalities ofthe system[ CITATION Mic175 \l 1033 ]. Therefore, various stages of input and output areexperienced, the true definition of an interface where system components interact to exchangecontent over a boundary. Stability – the interface between the cloud service and the Headspace system needs topromote a consistent and reliable performance.Flexibility – the protocols used by the external resources are unknown thus, the system’sinterface must be agile to accommodate any new element.
