Purchasing server instances and configuring them to run your own software is an example of which cloud deployment model?

1. SecaaS

2. PaaS

3. SaaS

4. IaaS

The correct answer is: IaaS

The selected answer, IaaS, is indeed the correct choice for this scenario. Infrastructure as a Service (IaaS) is a cloud computing model in which virtualized computing resources are provided over the internet. This includes server instances, storage, and networking. In IaaS, users have the ability to purchase virtual servers and configure them according to their needs, which allows for complete control over the software and operating systems being used. When you purchase server instances in an IaaS model, you get the underlying infrastructure managed by the cloud provider but maintain control over your applications, data, and operating system configurations. This flexibility is essential for businesses that wish to implement their own software solutions and customize their computing resources to meet specific requirements. The other options represent different cloud models that provide varying levels of abstraction and control. For example, PaaS (Platform as a Service) offers a platform allowing developers to build and deploy applications without managing the underlying infrastructure. SaaS (Software as a Service) delivers fully managed software applications over the internet, where users typically have little to no control over the infrastructure or the underlying platform. SecaaS (Security as a Service) focuses specifically on security solutions provided through the cloud, not encompassing the overall infrastructure services
