What is one effect of moving from a SaaS model to an IaaS model in cloud services?

Moving from a Software as a Service (SaaS) model to an Infrastructure as a Service (IaaS) model involves a significant shift in the way resources and services are managed. One of the key effects of this transition is the potential for increased risk. In a SaaS environment, the service provider manages the software applications, including security, updates, and maintenance, which generally offers a more controlled and secure experience for the user.

However, when utilizing IaaS, the responsibility for managing the infrastructure and the applications shifts more towards the user. Organizations must handle security, compliance, data management, and operational concerns at a granular level. This shift increases the complexity of management and potential vulnerabilities, such as misconfigurations or inadequate security measures, leading to a higher risk of data breaches or service disruptions.

Thus, as users take on more control and responsibility in the IaaS model, they also face a broader spectrum of risks associated with infrastructure management that they did not have to address in a SaaS model.
