ENHANCEDDYNAMICINFRASTRUCTURE AS A SERVICEMODEL (EDIAAS) FOR SELECTING SERVICE PROVIDER

The number of cloud service providers are expanding their services differ from one another. These have caused difficulty for user to choose the best services for a particular application. It is a tedious process for a user to search and select service providers before a chosen service can be extracted and compiled according to user preference. This process will repeat until all the desired services by user are compiled. Then the user has to rank the providers and make decision which provider fulfilled his need. Unfortunately user has to search the information again as it will be updated by the service provider. In this paper, we propose an Enhanced Dynamic Infrastructure as a Service Model (EDIAAS) for selecting service providers based on user need that incorporate important techniques such as worker role, cache redis and SignalR. The prominent services considered will be infrastructure as a service focusing on the speed of central processing unit (CPU), the size of random-access memory (RAM), the size solid-state drive (SSD), the bandwidth in bits per second (bit/s), and the cost of service. The experiments conducted shows that incorporating techniques such as worker role, cache redis and SignalR has increase system efficiency and reduce the time to display up to date information and the results instantly. This will ease the efficiency of user's search and ranking task in selecting cloud service provider.
