Leveraging Cloud-Based Infrastructure for Software Development
Question
A project manager is working with a team that is tasked to develop software applications in a structured environment and host them in a vendor's cloud-based infrastructure.
The organization will maintain responsibility for the software but will not manage the underlying server applications.

The organization plans to develop software applications in a structured environment and host them in a vendor's cloud-based infrastructure. However, the organization will maintain responsibility for the software but will not manage the underlying server applications. This indicates that the organization is leveraging a cloud service model, where the vendor provides infrastructure services for hosting the software applications while the organization maintains control of the software.
Out of the given options, the most appropriate cloud service model for this scenario is Platform as a Service (PaaS). PaaS is a cloud service model where the cloud provider offers a platform that enables the development, deployment, and management of software applications. This platform includes tools, middleware, and libraries required for application development and deployment.
PaaS enables the organization to focus on application development and maintenance while leaving the management of the underlying server infrastructure to the cloud provider. This allows for greater agility and scalability in the development and deployment process, as the organization can easily scale resources up or down as needed.
Software as a Service (SaaS) is another cloud service model that provides software applications to end-users over the internet. However, in this scenario, the organization is responsible for developing and maintaining the software applications, making SaaS an inappropriate option.
Infrastructure as a Service (IaaS) is a cloud service model that provides virtualized computing resources such as servers, storage, and networking to organizations. While IaaS can be leveraged to host software applications, it requires the organization to manage the underlying server infrastructure, which is not the case in this scenario.
Hybrid cloud is a cloud deployment model that combines public and private cloud services. While it can be leveraged to host software applications, it is not a cloud service model like PaaS, IaaS, or SaaS.
Network virtualization refers to the creation of virtual networks that are decoupled from the underlying physical network infrastructure. While it can be leveraged to optimize network performance, it is not a cloud service model and is not directly relevant to this scenario.
Therefore, the most appropriate option for the organization in this scenario is PaaS.
