What type of service model does not require the cloud provider to manage application software?

1. Infrastructure as a Service

2. Platform as a Service

3. Software as a Service

4. Backup as a Service

The correct answer is: Infrastructure as a Service

The correct choice for a service model where the cloud provider does not manage application software is Infrastructure as a Service (IaaS). In this model, the cloud provider offers fundamental computing resources such as virtual machines, storage, and networking, allowing users to manage their own applications and operating systems. Users have the flexibility to configure and run any software they choose on the provided infrastructure, which includes installing and managing their own application software. In contrast, Platform as a Service (PaaS) provides an environment that includes not just infrastructure but also development tools, middleware, and sometimes even the application software layer, leaving less responsibility for application management on the user's part. Software as a Service (SaaS) typically involves the cloud provider fully managing the application software, where users access the software over the internet without concern for the underlying infrastructure or the management of the applications. Backup as a Service (BaaS) is focused purely on data backups and recovery solutions rather than providing a framework for application software management. Thus, IaaS is uniquely positioned as the model that allows for maximum control and management of application software by the user, making it the correct answer.
