CHALLENGES, ISSUES AND PERFORMANCE AND OF CLOUD-BASED SYSTEMS IN BUSINESS INFORMATION SYSTEMS
1. Introduction:
Cloud is a collection of computing resources, such as software, servers and applications that are accessible via connectivity through the internet and offer their services to individuals or businesses.
Cloud-based services are categorized into:
1. Platform-as-a service (PAAS)
2. Software-as-a-service (SAAS)
3. Infrastructure-as-a-service (IAAS)
· Different Industries manages a huge amount of heterogonous data and it grows rapidly as the processes grow, So data integration technique is required such that in real sense it provides true business value by consolidating data of different phases of the lifecycle of a project because a wrong decision can be made without having overall project data view in terms of profitability and performance of a project [1].
· Traditional based ICT i.e. Information and communication technologies require more expensive hardware and software state of art equipment and it is also less flexible as compared to the cloud base setup.
· Cloud computing in Business Information systems allows improved and updated access to ICT systems and reduced capital expenditure [1].
Large scale companies employ their cloud solutions to support processes with the help of shared architecture for different services, which may be private or hybrid.
1.1. Features of Cloud Technology:
· Resources such as processing power, database storage etc can be utilized by the customer.
· Using Cloud, resources can be accessed anytime from anywhere.
· The resources can be shared by multiple customers that may spread across different locations.
· Resources can be allocated to users on-demand based on customer requirements.
· They are adaptive, balanced and transparent systems [2].
2. Literature background:
To frame and support our research, identification, analysis and review of the literature of cloud-based information systems is done. Based on the research, the challenges are also addressed of a cloud-based business information system.
2.1. Cloud-based information systems:
These are the Information systems that are based on clouds where all the services are prompt to the demand of users across a network irrelevant of user location or the device and it allows...
