Event-Driven Payroll Processing Using Function-as-a-Service Architectures

Traditional HR systems rely heavily on on-premises infrastructure. These legacy architectures deploy applications as Windows services or Unix daemons. These services execute business logic to validate timesheets, calculate gross pay, process deductions, compute net pay. Implementing these workflows using Function-as-a-Service (FaaS) offerings from cloud providers eliminates infrastructure overhead while reducing hardware, software and operational costs.
