Explanation / Answer

It depends based on the scenario of an organization and what is its real use to select which kind of service it should choose.IaaS (Infrastructure as a Service) is used when the consumer does not deal with the infrastructure, instead the responsibility of the equipment is outsourced to the Service Provider. The Service Provider not only owns the equipment but will also be responsible for its running and maintenance, where the consumer will be charged on a ‘pay as you use’ basis.PaaS provides the capability for consumers to have applications deployed without the burden and cost of buying and managing the hardware and software. In other words these are either consumer created or acquired web applications or services that are entirely accessible from the Internet. Software as a service (SaaS) is the ability for a consumer to use on demand software that is provided by the service provider via a thin client device e.g. a web browser over the Internet. With SaaS the consumer has not only no management or control of the infrastructure such as the storage, servers, network, or operating systems, but also no control over the application’s capabilities. Monitoring as a Service (MaaS) is at present still an emerging piece of the Cloud jigsaw but an integral one for the future.
