Click on the arrows to vote for the correct answerA. B. C. D.
The cloud model that can be used to host the customized e-commerce web application with multiple virtual machines, block storage, databases, load balancer, and a web application firewall is Infrastructure as a Service (IaaS).
IaaS is a cloud computing model that provides customers with virtualized computing resources over the internet. In an IaaS model, the cloud service provider is responsible for providing and maintaining the physical infrastructure, while the customer is responsible for managing the operating system, middleware, applications, and data.
In this scenario, the customer wants to deploy a customized e-commerce web application using multiple virtual machines, block storage, databases, load balancer, and a web application firewall. With IaaS, the customer can easily deploy and manage the required virtual machines and storage resources on the cloud service provider's infrastructure. Additionally, the customer can install and manage the necessary software components on these virtual machines, including the web application, databases, and web application firewall.
The load balancer can also be provisioned as an IaaS resource and configured to distribute traffic across the deployed virtual machines to ensure high availability and scalability of the application.
Overall, IaaS is a suitable cloud model for hosting this customized e-commerce web application as it provides the necessary flexibility and control for the customer to deploy and manage their application components while leveraging the cloud service provider's infrastructure.
