Server and Client


Whenever we talk about any software, we immediately get interested in its application architecture. The client and the server are the basic components of the most famous Client-Server software architecture. A client is defined as an entity that initiates a request to establish a connection whereas a server is that entity which waits for the request generated by a client and establishes a connection. In this article, we will explain to you the client-server model, responsibilities of a client and a server, advantages, and disadvantages of the client-server model and finally, we will talk a little about StarWind Proactive Support.[1] [2] [3] 

Client-Server Model:[4] 

As stated earlier, a client-server model is one of the many models of the software architecture. [5] A client and a server program can reside either inside the same computer system or on different computer systems. A server usually has a one to many relationship with the clients i.e. a server can handle multiple requests from the same client or it can serve multiple requests from different clients at a time. A user interacts with the client side of this architecture and he cannot contact the server directly in most of the cases.

In a client-server model, a server is all the time in the listening state. As soon as any client initiates a request, a server can either accept or reject this request. [6] If the server accepts the request, a connection is established which serves as a communication channel between the client and the server. Now the client can ask for whatever resources it needs and the server will fulfill this request according to its capacity and respond back to the client. This is how the client-server model works.  [7] 

Responsibilities of a Client:

The basic responsibilities of a client are as follows:

●       Initiate the connection establishment request

●       Wait for the reply from the server

●       Request for resources from the server

Responsibilities of a Server:

The basic responsibilities of a server are as follows:

●       Listen to the client requests all the time

●       Reply back to the client in order to establish a connection

●       Serve the client by fulfilling its requests and granting the required resources

Advantages of the Client Server Model:

Following are the advantages of the client-server model:[8] 

➢      Easier to maintain centrally

➢      Increased level of safety and security

➢      Better performance

➢      Accessibility

➢      Resource sharing

Disadvantages of the Client Server Model:

Following are the disadvantages of the client-server model:[9] 

➢      Single point of failure

➢      Overloaded server

➢      Servers are more complex

➢      Servers are more expensive
