HR SaaS didn’t slink in from the shadows and creep up on HR departments. The concept is actually much older. Software-as-a-Service (SaaS) traces its roots to application service providers in the 90s, which were in turn predecessors to timesharing services in the 70s.
SaaS is now solidly in the IT vernacular. Supported by additional innovation in virtualization and both client-side and server-side encryption, cloud computing is clearly mainstream.
