Networking Needs and Security 1. “What are the key components of a typical P2P application? Describe their functions.”

There are myriad components that play vital roles in typical P2P applications. Perhaps the most salient of these is a server—a file server, in particular. Because of the connected, transferable nature of P2P networks, most applications are designed to exploit this connectivity by sharing data. In this regard, a P2P network functions as a microcosm of the vision of the semantic web. Nonetheless, most applications have some functionality which acts as a file server, enabling the exchange of information between other applications and servers in the network in question. Another integral aspect of the vast majority of applications for P2P networks is their processors, or core processors in several instances. These processors provide vital functionality related to the redundancy which functions at the center of the way most of the machines (and their applications) on these networks operate. These processors are also involved in the failover capabilities (Beaver, 2003) of these applications which helps them to continue functioning properly in the wake of instances in which failure might occur. Additionally, most P2P applications have some sort of capabilities for delivering messages between those on the network. These messages are one of the important ways that information is communicated on these networks. The combination of these components enables some of the critical procedures for file sharing, for which these type of networks are widely renowned.

2. What are the essential features of a typical hybrid network architecture design?

Still, the most critical of these are the confluence of both on-premise and cloud infrastructure. The tandem of these two architectural types is what make a hybrid architecture a synthesis (Burke, 2017). Such architecture must involve the cloud as well as conventional on-premise infrastructure. Thus, it could involve a combination of VMware accessible through the cloud in addition to physical servers behind an organization’s firewall. Firewalls are typical security manifestations found within the design of these hybrid network architectures. Competitive organizations are able to get some of their cloud assets within their secure firewall with their on-premise applications. In terms of the cloud aspect of such a hybrid network, it is necessary for an organization to have any variety of internet connection (mobile, landline, etc.) in addition to an internet service provider and a cloud service provider. Essential features of this architectural design include both on-premise servers and, oftentimes, those in the cloud. In addition to the example of virtualized servers denoted above, organizations may also frequently utilize some combination of Infrastructure as a Service (IaaS) for cloud servers. Another pivotal component is adequate bandwidth involved to keep data suitably transmitting from the cloud to on-premise locations, and replicated from the latter to the former as need be. Common methods for accounting for such bandwidth include Wide Area Networks (WAN), although in some instances LANs may provide a fair amount of utility in this regard as well.
