Which of the following is an example of SaaS?

Salesforce is a prime example of Software as a Service (SaaS) because it provides a cloud-based application that users can access via the internet to manage customer relationships and sales processes. With SaaS, the software is hosted in the cloud, allowing users to use it on demand without the need for local installation, maintenance, or significant upfront costs. Users benefit from automatic updates, scalability, and the ability to access the service from any location with internet connectivity.

In comparison, the other options represent different types of services. AWS, Google Cloud, and Azure are primarily examples of Infrastructure as a Service (IaaS) and Platform as a Service (PaaS), providing a broader range of cloud computing resources such as storage, computing power, and application hosting platforms. These services allow developers and organizations to build, deploy, and manage applications rather than delivering specific software applications like Salesforce.
