Software-as-a-Service, “SaaS”, or simply “sass”, is a cloud offering that provides
users with access to a service provider’s cloud-based software.
SaaS providers maintain the servers, databases, and code that constitute an application.
They also manage access to the application, including security, availability, and performance.
Applications reside on a remote cloud network, and users use these applications without having
to maintain and update the infrastructure.
Core business processes supported by SaaS today / include
email and collaboration via offerings such as Microsoft's Office 365 and Google's Gmail,
Customer Relationship Management via services such as NetSuite CRM and Salesforce,
Human Resource Management via services from Workday and SAP SuccessFactors,
financial management, billing and collaboration, and many more.
According to Forrester Research, SaaS has overtaken on-premises solutions in categories
such as human capital management (HCM), customer relationship management (CRM), and collaboration.
Solutions once available with several different deployment options are now SaaS-only.
Let’s look at key characteristics of Software-as-a-Service: SaaS clouds have a multitenant architecture.
Infrastructure and code are maintained centrally and accessed by all users.
