Client Server vs peer to peer

The client server and peer to peer are two network architectures.

In the client server architecture, tasks or workloads are partitioned between servers and services are requested by clients. Typically, clients and servers communicate over a computer network, but they can also reside on the same system.

In the peer to peer architecture, tasks or workloads are partitioned between peers and are deemed to form a peer to peer network. Peers have the same potential and the same privileges. Peers make some of their resources, such as processing power, disk storage, or network bandwidth, available to other network participants.

What is the client server ?

As mentioned previously, the client server architecture is based on the concept of servers providing services and on a set of clients requesting these services. A server is actually a host that runs one or more server programs, which share their resources with clients. The client initiates the communication session with the servers by requesting the content or the services of the server. The servers are still waiting for incoming requests from clients. There are several varieties of client servers today. But they also have several common features such as a centralized security database, which controls access to shared resources on the server. The server contains a list of usernames and passwords and a user doesn’t is allowed to access the network only if it supplies the server with a valid user name and password. After logging in, users can only access resources for which the network administrator has granted permission. Widely used functions such as email exchange, web access and database access are built on the client-server architecture.

What is Peer to Peer?

In a peer to peer network, resources are shared among peers without any central coordination by a server. Peers act as both providers and consumers of resources. Peer-to-peer systems implement an abstract overlay network at the application layer, above the physical network topology. The idea of ​​peer to peer networks is to share resources at a lower cost. There is no centralized security system, and end users are themselves empowered to control access to resources, thereby reducing security in peer-to-peer networks. Users can create any share point of their choice on their computer and security can only be ensured by assigning a password when creating the share point.

Difference between client-server and peer-to-peer network architectures ?

There are number of difference between client server and peer to peer systems architecture.

In the client-server architecture, there are designated clients requesting services and then server provides them services.

On the other hand peer to peer systems, counterparts act both consumers.

In addition, client-server systems require a central file server and their implementation is expensive compared to peer-to-peer systems.

On the other hand, in the client-server system, a dedicated file server provides a level of access to clients, offering increased security compared to peer-to-peer systems in which security is managed by end users.

Problems with peer to peer and client server architecture:

Problem of Peer to Peer Architecture: The performance of peer to peer networks suffers from the increase in the number of nodes.

Problem of client server systems: It is more stable and can be scaled as much as you need. Therefore, selecting one over the other depends on the environment you need to implement.
