Infrastructure as a service (IaaS) is an instant computing infrastructure, provisioned and managed over the internet. The IaaS service provider manages the infrastructure, while you purchase, install, configure, and manage your own software
Incorrect Answers:
A: Software as a service (SaaS) allows users to connect to and use cloud-based apps over the Internet. Common examples are email, calendaring, and office tools. In this scenario, you need to run your own apps, and therefore require an infrastructure.
B:
Platform as a service (PaaS) is a complete development and deployment environment in the cloud. PaaS includes infrastructure"servers, storage, and networking"but also middleware, development tools, business intelligence (BI) services, database management systems, and more. PaaS is designed to support the complete web application lifecycle: building, testing, deploying, managing, and updating.

The solution you choose should be able to accommodate the installation of prerequisite applications and services for each application.
A. Software as a Service (SaaS): This cloud deployment model allows customers to access and use software applications hosted on a cloud provider's infrastructure. In this case, the applications would be fully managed and provided to the company as a service without the need for the company to manage any infrastructure. However, since the applications are pre-built and hosted by the cloud provider, there may be limitations on the customization and integration options for the company.
B. Platform as a Service (PaaS): This cloud deployment model provides a platform for customers to build, deploy, and manage their own applications without having to worry about the underlying infrastructure. In this case, the company would have the ability to install the prerequisite applications and services required for their custom invoicing applications on the PaaS platform. This would allow for greater flexibility and customization options than SaaS, but still offload much of the infrastructure management to the cloud provider.
C. Infrastructure as a Service (IaaS): This cloud deployment model provides virtualized computing resources, including servers, storage, and networking, as a service. In this case, the company would have full control over the virtual machines and infrastructure that their custom invoicing applications run on. This option would provide the greatest level of customization and control, but also requires the most infrastructure management from the company.
Based on the requirements of this scenario, the recommended cloud deployment solution would be B. Platform as a Service (PaaS). This would provide the company with the ability to install and manage the prerequisite applications and services required for their custom invoicing applications, while offloading much of the underlying infrastructure management to the cloud provider.
