What does IaaS primarily offer to users in a cloud environment?

  1. Managed application services

  2. Virtualized computing resources over the internet

  3. Complete platform management

  4. Software solutions as a service

The correct answer is: Virtualized computing resources over the internet

IaaS, or Infrastructure as a Service, primarily provides users with virtualized computing resources through the internet. This model allows customers to access essential infrastructure components such as virtual machines, storage, and networking resources on demand. Users can scale these resources up or down based on their needs, benefiting from flexibility and cost-effectiveness without the need to invest in physical hardware. IaaS is distinct from other cloud service models. For instance, managed application services and software solutions as a service focus on providing end-user applications and software management rather than raw computing power. Similarly, complete platform management, which might involve development environments and application hosting, is more aligned with the Platform as a Service (PaaS) model. Thus, the choice that accurately represents the core offering of IaaS is the provision of virtualized computing resources over the internet.
