Along with infrastructure as a service and platform as a service, SaaS is one of the three primary types of cloud computing. SaaS apps are used by a wide range of IT experts, commercial users, and consumer users. Personal entertainment, such as Netflix, to advanced IT tools, are all available. SaaS products, unlike IaaS and PaaS, are commonly offered to both B2B and B2C customers.
The cloud delivery model is used for SaaS. An ISV can hire a cloud provider to host the application and related data in the provider's data center or a software provider can use its own servers, databases, networking, and computing resources to host the program and related data. Any device with a network connection will be able to use the app. Web browsers are commonly used to access SaaS apps.
