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.
