Option 4 : 1, 2 and 3
The correct answer is 1,2, and 3.
Software as a Service (SaaS)
- Software as a service(SaaS) is defined as the software distribution model deployed on the internet in which a cloud service provider provides applications. It is also known as "on-demand software" or "pay-as-you-go application".
- Software as a service (SaaS) allows users to connect and use cloud-based apps over the Internet. Common examples are email, calendaring and office tools (such as Microsoft Office 365).
- SaaS provides a complete software solution that you purchase on a pay-as-you-go basis from a cloud service provider. You rent the use of an app for your organization and your users connect to it over the Internet, usually with a web browser. Hence, statement 1 is correct.
- Access app data from anywhere. With data stored in the cloud, users can access their information from any Internet-connected computer or mobile device. And when app data is stored in the cloud, no data is lost if a user’s computer or device fails. Hence, statement 2 is correct.
- If you have used a web-based email service such as Outlook, Hotmail or Yahoo! Mail, then you have already used a form of SaaS. With these services, you log into your account over the Internet, often from a web browser. The email software is located on the service provider’s network and your messages are stored there as well. You can access your email and store messages from a web browser on any computer or Internet-connected device. Hence, statement 3 is correct
