adell [148]

Answer:

The user does not need to purchase and install additional hardware to provide increased capacity.

Explanation:

Cloud computing can be defined as a type of computing that requires shared computing resources such as cloud storage (data storage), servers, computer power, and software over the internet rather than local servers and hard drives.

Generally, cloud computing offers individuals and businesses a fast, effective and efficient way of providing services.

Cloud computing comprises of three (3) service models and these are;

1. Platform as a Service (PaaS).

2. Infrastructure as a Service (IaaS).

3. Software as a Service (SaaS).

Software as a Service (SaaS) can be defined as a cloud computing delivery model which involves the process of making licensed softwares available over the internet for end users on a subscription basis through a third-party or by centrally hosting it. Some examples of SaaS are Go-ogle apps, Bigcommerce, Salesforce, Slack, Dropbox, DocuSign, Microsoft Office 365, etc.

An advantage of the software as a service (SaaS) approach in public cloud computing is that the user do not have to purchase and install additional hardware to provide increased capacity because the software provider makes all of the necessary features for smooth operations and proper functioning available to the user.
