This level of control is essential for organizations that require customization of their infrastructure to meet specific application needs or compliance requirements.

In an IaaS model, organizations can deploy operating systems and applications of their choice, configure network settings, and scale resources up or down based on demand. This flexibility is one of the key advantages of IaaS, enabling businesses to optimize costs and manage workloads efficiently. Users are responsible for managing the operating systems and any applications they choose to install, which underscores the level of control they have over the infrastructure.

In contrast, managed environments with software oversight typically refer to software as a service (SaaS), where users leverage applications hosted on the provider's infrastructure, thus relinquishing control over the underlying hardware. Subscription-based software delivery aligns more closely with SaaS or platform as a service (PaaS) rather than IaaS. Pre-configured applications fit within the realm of SaaS as well, where applications
