Software as a Service (SaaS) is a cloud-based software delivery model where applications are hosted by a third-party provider and made available to users over the internet. Unlike traditional software that is installed and maintained on local computers or servers, SaaS applications are fully managed and maintained by the vendor, including software updates, security patches, and scalability.
SaaS is widely used across various industries because it allows users to access sophisticated software without the need to install or maintain it on their devices or servers. Popular examples of SaaS applications include platforms like Google Workspace (formerly G Suite), Salesforce, Dropbox, and Slack.
