Definition
Software as a Service - the delivery model Salesforce pioneered where CRM software is hosted in the cloud and accessed via web browser, with no local installation required, automatic updates, and subscription-based pricing.
In plain English
“SaaS (Software as a Service) is the cloud delivery model that Salesforce pioneered. Instead of installing CRM software on your own servers, you access it through a web browser, get automatic updates, and pay a subscription fee. It's how nearly all modern business software works now.”
Worked example
A newly-hired CIO at Copperline Logistics evaluates two CRM options: Salesforce (Software-as-a-Service) and a competing on-premise system requiring a dedicated Oracle DB and four app servers. Choosing Salesforce SaaS means no servers to rack, no database to patch, Salesforce's three-times-yearly releases apply automatically without downtime, and billing is per-user per-month. The on-prem alternative requires capex, a sysadmin hire, and quarterly maintenance windows — the SaaS model removed those entirely, letting the CIO focus on business configuration rather than infrastructure. Salesforce pioneered the SaaS CRM model starting in 1999.
Why SaaS matters
SaaS (Software as a Service) is the delivery model Salesforce pioneered where CRM software is hosted in the cloud and accessed via web browser, with no local installation required, automatic updates, and subscription-based pricing. Before Salesforce launched in 1999, enterprise software required buying licenses, installing on your own servers, and managing upgrades yourself.
SaaS transformed the software industry by shifting operational burden from customers to vendors. Customers don't manage servers, don't handle upgrades, and don't worry about infrastructure scaling. Salesforce gets credit for mainstreaming SaaS for enterprise software, but the model has since become the default for nearly all business applications. Understanding SaaS concepts is foundational to understanding why Salesforce works the way it does: multi-tenancy, automatic releases, and subscription pricing are all consequences of the SaaS model.
