ASP (application service provider) rents applications to users instead of buying software, the user pays for using applications as and when they need them. 9 Applications Programs: Application Service Provider The ASP provides the software, manages the hardware and provides storage space, security controls and the physical links to customers. The ASP normally leases storage space for programs and data from data centers which are facilities for storing large amounts of information owned by data storage specialists. 10 Applications Programs Application Service Provider The user is provided with remote access across a communications network to a wide variety of programs including: Generic applications such as email and office suites, high-end (advanced) packages including large, complex business applications such as enterprise resource planning tools e.g. SAP Business services, such as payroll and accounting systems Expensive specialist tools e-commerce (buying and selling on the Internet)resources. 11 Advantages of ASP This gives the user more flexibility 2) Saves them having to install and maintain programs, upgrade (install newer versions of programs), deal with viruses (programs that can reproduce themselves and are written with the purpose of causing damage or causing a computer to behave in an unusual way) and manage email systems. 1) 12 Disadvantages of ASP The need for a broadband (high bandwidth i.e. a connection with a high signal capacity) network connection or a leased line ( a cable connection that is rented for use in a communications system) 2) Dependence on the ASP to provide a secure, reliable, rapidly available service. 1) 13 Unit 8: Applications Programs Starter 1 A.
