Which cloud service model is recommended for a company needing hardware capacity to host a production database application?

1. CaaS

2. XaaS

3. IaaS

4. PaaS

The correct answer is: PaaS

For a company that needs hardware capacity specifically to host a production database application, the Infrastructure as a Service (IaaS) model is the most suitable choice. IaaS provides virtualized computing resources over the internet, allowing businesses to rent servers, storage, and networking from a cloud provider. Choosing IaaS empowers organizations with greater control over their infrastructure compared to other service models. This is crucial for hosting production databases, as companies require customizable environments where they can install and manage their database applications, configure network settings, and allocate resources based on performance needs. IaaS not only enables scalability and flexibility but also allows companies to avoid the financial and logistical burdens of maintaining physical hardware. They can easily scale resources up or down based on demand, ensuring that they only pay for what they use. This is particularly important for database applications, which may experience fluctuating loads depending on the business requirements. Thus, IaaS aligns perfectly with the need for robust hardware capacity in cloud-hosted applications.
