Application Server: An application server allows client computers to run licenced applications without needing to be installed locally. Advantages: Saves much time compared to installing a copy on every client machine. Disadvantages: Expensive to set up. Overkill for a network with only a few client computers.

Server virtualization is the process of dividing a physical server into multiple unique and isolated virtual servers by means of a software application. Each virtual server can run its own operating systems independently. Advantages: Cuts down on energy consumption since there are fewer physical servers consuming power.

Hybrid cloud storage: Hybrid cloud refers to mixed computing, storage, and services environment made up of on-premises infrastructure, private cloud services, and a public cloud—such as Amazon Web Services or Microsoft Azure—with orchestration among the various platforms. Advantages: The primary benefit of a hybrid cloud is agility. The need to adapt and change direction quickly is a core principle of a digital business. Your enterprise might want (or need) to combine public clouds, private clouds, and on-premises resources to gain the agility it needs for a competitive advantage. Disadvantages: Although the long-term cost savings are one of the many benefits, the initial deploying cost of a hybrid cloud exceeds as compared to the setup cost incurred in the case of a public cloud. While creating a hybrid cloud environment, specific hardware is required to deploy on-premises, and that’s what shaves off a large chunk of the budget.

Cloud storage is a cloud computing model that stores data on the Internet through a cloud computing provider who manages and operates data storage as a service. It's delivered on-demand with just-in-time capacity and costs and eliminates buying and managing your own data storage infrastructure.
