Cloud computing: Technology that allows users to access computing resources and services over the Internet
                  without having to purchase them at their workplace.



                    Match the following:
                    1.  Infrastructure as a Service (IaaS)   a.   Provides  users  with  a  platform  for  building,  deploying,
                                                          and managing applications without having to worry about
                                                          the underlying infrastructure.
                    2.  Platform as a Service (PaaS)    b.   Provides users with access to software applications and
                                                          services, such as email, CRM, and productivity tools, over
                                                          the Internet.
                    3.  Software as a Service (SaaS)    c.   Provides  users  with  access  to  virtualized  computing
                                                          resources, such as servers, storage, and networking, that
                                                          can be used to build and deploy applications and services.


            In addition to these service models, cloud computing can also be classified based on deployment models:
            1.   Public cloud: A public cloud is a cloud infrastructure that is owned and operated by a third-party cloud service
               provider and made available to the public over the Internet.
            2.   Private cloud: A private cloud is a cloud infrastructure that is owned and operated by a single organisation and
               made available to internal users over a private network.
            3.   Hybrid cloud: A hybrid cloud is a combination of public and private cloud infrastructures, where workloads can be
               moved between the two environments based on workload demands.
