Which service model would be most appropriate for a company seeking to provide infrastructure resources like virtual machines?

The most appropriate service model for a company seeking to provide infrastructure resources like virtual machines is Infrastructure as a Service (IaaS). This model offers virtualized computing resources over the internet, allowing organizations to rent infrastructure components such as servers, storage, and networking.

IaaS is particularly beneficial for businesses that require flexibility in scaling their computing resources up or down based on demand. By utilizing IaaS, companies can focus on building and managing their applications while relying on the service provider to handle the underlying physical hardware and networking components.

In the context of providing virtual machines, IaaS allows companies to rapidly deploy and manage their virtualized environments without the burden of purchasing and maintaining physical servers. This model is designed specifically for organizations needing control over their infrastructure setup while still benefiting from the scalability and cost-effectiveness of cloud services.
