A detailed enterprise-wide analysis of the current infrastructure of a large corporation identified three key findings: 1. Mainstream business processes 2. Light data volumes 3. Low regulations or…

Public cloud is designed for broad, general-purpose workloads where regulatory and compliance burdens are minimal and data volumes are manageable by shared infrastructure. It provides on-demand scalability and cost efficiency by sharing resources across multiple tenants, making it ideal when there is no strong driver for dedicated private resources or strict data sovereignty controls. All three findings - mainstream processes, light data volumes, and low compliance - align precisely with the value proposition of public cloud.

Private cloud is typically chosen when organizations face strict regulatory, compliance, or data sovereignty requirements that prevent use of shared public infrastructure, which is the opposite of what was found.

PaaS (Platform as a Service) is a cloud service model describing what is delivered to consumers, not a deployment model that describes where or how the cloud environment is hosted.

SaaS (Software as a Service) is a cloud service consumption model for specific applications, not a deployment model that can be selected based on infrastructure or compliance characteristics.
