What type of service allows an organization to provision servers in a cloud environment while maintaining internal controls?

1. Infrastructure as a Service

2. Platform as a Service

3. Software as a Service

4. Function as a Service

The correct answer is: Infrastructure as a Service

Infrastructure as a Service (IaaS) is the correct choice because it enables organizations to provision and manage virtualized computing resources over the internet. With IaaS, businesses can create and control their own servers, storage, and networking equipment while taking advantage of the scalability and flexibility of a cloud environment. This model allows organizations to maintain internal controls by giving them the ability to configure and manage their operating systems, applications, and security settings just as they would in an on-premises environment. In contrast, other models such as Platform as a Service (PaaS) and Software as a Service (SaaS) provide different levels of abstraction where the user has less control over the underlying infrastructure. PaaS gives users a platform to develop and deploy applications without worrying about the underlying hardware, while SaaS delivers completed software solutions that users access via the internet, with little to no ability to customize the environment. Function as a Service (FaaS) is focused on executing individual functions in response to events without managing servers at all, which does not align with the need for maintaining internal controls over server provisioning.
