Learn more about software as a service in the given explanation below.

Explanation:

• Software as a service (SaaS) is a software distribution model in which a cloud provider hosts applications and makes them available to end users over the internet. In this model, an independent software vendor (ISV) may contract a third-party cloud provider to host the application.
• In the software-on-demand SaaS model, the provider gives customers network-based access to a single copy of an application that the provider created specifically for SaaS distribution. The application's source code is the same for all customers, and when new features or functionalities are released, they are rolled out to all customers. Depending on the service-level agreement (SLA), the customer's data for each model may be stored locally, in the cloud or both locally and in the cloud. Organizations can integrate SaaS applications with other software using application programming interfaces (APIs). For example, a business can write its own software tools and use the SaaS provider's APIs to integrate those tools with the SaaS offering. Thus, SaaS buyers can customise the user interface and can change data fields. This also allows SaaS users to access their data through their mobile devices. So, statement 1 and statement 2 are correct.
• Email services are also an example of SAAS, which are provided by companies like Yahoo, Hotmail and Outlook. So, statement 3 is correct.

Advantages of SaaS

SaaS offers several advantages over traditional software deployment, including:

• Reduced IT burden: Organizations eliminate the need to install, run, and maintain software on their own servers, reducing their IT burden.
• Cost savings: SaaS removes the upfront costs of hardware and software purchases, as well as the ongoing costs of maintenance and support.
• Flexible pricing: SaaS offers subscription-based pricing models, allowing organizations to pay only for the resources they use.
• Scalability: SaaS applications can easily scale up or down to meet changing business needs.
• Automated updates: SaaS providers automatically handle software updates, ensuring that users are always working with the latest version.
• Accessibility: SaaS applications can be accessed from anywhere with an internet connection, providing greater flexibility for users.
• Customizability: SaaS applications can be customized to meet the specific needs of an organization.
• Integration: SaaS applications can be integrated with other business applications to streamline workflows.

Therefore, option (d) is the correct answer.
