A. B. C. D.C.
The best cloud-hosting option for the enterprise-wide application with a large database, requiring a capital investment in hardware, and reducing the reliance on the datacenter is Hybrid IaaS.
Explanation: A. Multi-tenancy SaaS: Software as a Service (SaaS) is a cloud computing model where a third-party provider hosts applications and makes them available to customers over the internet. Multi-tenancy means that multiple customers share the same application instance and database, but their data is kept separate. However, SaaS may not be the best fit for this scenario as the application requires a large database, which may not be cost-effective to store in a multi-tenant environment.
B. Hybrid IaaS: Infrastructure as a Service (IaaS) is a cloud computing model where a third-party provider hosts infrastructure components such as servers, storage, and networking hardware. Hybrid IaaS combines public and private cloud resources to provide more flexibility, cost-effectiveness, and control. In this scenario, the enterprise can save money and reduce reliance on the datacenter by using public cloud resources to host the database while keeping the application itself on-premises or in a private cloud.
C. Single-tenancy PaaS: Platform as a Service (PaaS) is a cloud computing model where a third-party provider offers a platform for customers to develop, run, and manage their applications without worrying about the underlying infrastructure. Single-tenancy means that each customer has their own dedicated instance of the platform and resources. However, PaaS may not be the best fit for this scenario as the application requires a large database, which may not be cost-effective to store in a single-tenant environment.
D. Community IaaS: Community IaaS is a cloud computing model where a third-party provider offers infrastructure resources to a specific community of customers with similar needs and requirements. Community IaaS may not be the best fit for this scenario as the enterprise requires a large database, which may not be cost-effective to store in a shared environment with other customers.
Therefore, Hybrid IaaS would best meet the needs of this scenario by providing a cost-effective solution for hosting the large database in the public cloud while keeping the application itself on-premises or in a private cloud, thus reducing reliance on the datacenter.
