The company is utilizing Software as a Service (SaaS). SaaS delivers fully managed software applications over the internet, allowing users to access them directly without the need for installation, maintenance, or management of the underlying infrastructure. The cloud provider manages all aspects of the application, including updates and security. In contrast, Platform as a Service (PaaS) offers a platform for users to develop, run, and manage their own applications, which requires involvement in the application environment. Infrastructure as a Service (IaaS) provides virtualized computing resources over the internet, but users are responsible for managing operating systems and applications. Private Cloud Service refers to cloud services used exclusively by one organization, which may not necessarily involve outsourcing to a third-party provider.
