SaaS–Software as a Service
SaaS: Software as a Service: Pronounced “sass”
You see SaaS everywhere—from job descriptions to product advertisements, so it’s important to know what this means.
From Wikipedia: This type of cloud computing delivers a single application through the browser to thousands of customers using a multitenant architecture. On the customer side, it means no upfront investment in servers or software licensing; on the provider side, with just one app to maintain, costs are low compared to conventional hosting. Salesforce.com is by far the best-known example among enterprise applications, but SaaS is also common for HR apps and has even worked its way up the food chain to ERP, with players such as Workday. And who could have predicted the sudden rise of SaaS “desktop” applications, such as Google Apps and Zoho Office?
Software as a service, sometimes referred to as “on-demand software,” is a software delivery model in which software is hosted centrally (typically in the (Internet cloud) and is accessed by users using a thin client, typically a web browser over the Internet.
While practically every Internet service (such as Web search engine or web-based Email) is driven by some underlying software, the term software-as-a-service is often used in the context of business software, and in some cases even more narrowly as software in a category which has on-premise software; i.e., equivalent software that is installed in businesses’ computer networks or personal computers.
SaaS has become a common delivery model for most business applications, including accounting, collaboration, customer relationship management (CRM), enterprise resource planning (ERP), invoicing, human resource management (HRM), content management (CM) and service desk management.
