Software as a Service (SaaS) is a cloud computing model where applications are hosted by a service provider and made available to customers over the internet. Users can access SaaS applications from any internet-enabled device, which makes it a popular choice for businesses.
SaaS works by hosting applications on a cloud service provider's infrastructure.
A business, BizCorp, needs a customer relationship management (CRM) system. Instead of buying and installing a CRM software on their own servers, BizCorp subscribes to a SaaS-based CRM system. They access the system over the internet, and the SaaS provider takes care of all the maintenance and upgrades.
A cloud computing model that provides customers a complete platform—hardware, software, and infrastructure—for developing, running, and managing applications without maintaining the infrastructure.
