advantages of Peer to Peer over Client to server type of distributed systems

Comparing Network Models: P2P vs. Client-Server           Computer networks are built and run on two fundamental network models that is peer-to-peer (P2P) and client-server. In spite of the fact that it is basic to networking, these models vary altogether in design, resource management, scalability, centralization, and security. These refinements make them perfect for a diversity of network settings, depending on the application's special necessities.Peer-to-Peer (P2P) Network Model           All devices in a P2P network, called peers, have the same right. They are also peers as they have a dual function as that of clients and servers. In essence, this implies that peer-to-peer applications will allow users to not only acquire additional resources but also supply resources of their own. Resources like files and processing power are dispersed in the network while it is decentralized. This model is most effective when resource distribution, resilience, and decentralization hold sway. Some of these are file sharing platforms such as bit torrent, group works and peer-to-peer networks direct communication such as voice and video chat.Client-Server Network Model           However, the client-server model exhibits a separate nature of clients and servers. The servers are a source of power that centralize the storage and management of resources and provide services to clients who make demands using and receive these resources. Resource allocation and control is centralized for scalability and security. For such applications as centralized control, scalability, and high security, client-server network is well suited. Some common applications are web hosting services, email servers, cloud computing platforms, and database management operations. However, in a case where such networks are client-server network then there are various issues to do with stability. The reliance on centralized servers may cause outage or hacking which calls for stability.Tailoring the Network Model to Your Needs           The choice between P2P and client-server network architectures is decided by the network application's special necessities. When choosing an appropriate model, components such as resource allocation, scalability, security, and centralization must be carefully inspected. P2P networks exceed expectations in settings requiring decentralized resource sharing and resilience, though client-server networks give versatility and centralized control for successful benefit and data administration. These models reflect two restricting approaches to networking, each with its possess set of focal points and downsides that cater to a wide extend of network necessities.
