Explanation:
You will most likely have to provide and manage the customer relationship management (CRM) application. A PaaS vendor provides operating systems, software development platforms, and database platforms, as well as the underlying network infrastructure and the raw computing and storage resources. PaaS is often used by companies that want to migrate their application development to a cloudbased solution. However, a PaaS customer must use whatever software development platformis supported by the PaaS vendor, so a degree of control and flexibility is lost. The PaaS vendor is responsible for maintaining the operating systems, software development platforms, and database platforms, as well as any underlying hardware infrastructure.
An Infrastructure as a Service (IaaS) vendor provides computing and storage resources aswell as the network infrastructure. The customer is responsible for everything else, including operating systems, software development platforms, database platforms, and software applications. With IaaS, the customer has a great deal of control and flexibility.
However, IaaS places a larger management burden on the customer than the other cloudbased services do. If you were to use an IaaS vendor, you would have to provide and manage the CRM application, the operating system, and the software development platform.
A Software as a Service (SaaS) vendor typically provides a complete software applicationpackage to customers. For example, a company might contract with a SaaS vendor to provide hosted email services. The software application, the operating system on which the application runs, the hardware on which the operating system runs, and the network infrastructure on which the hardware communicates are maintained by the SaaS vendor, thereby lowering the managementburden for the customer. Access to the software application is often provided through a web browser interface. If you were to use a SaaS vendor, you would not have to provide or manage anything? however, youwould have to use whatever platforms and CRM applications that the SaaS vendor has available.
