Client-Server Architecture could be seen as a computing model in which a dedicated computer hosts, delivers, and manipulates a resource and service requested by a user (client). This architecture is a type that allows interconnection between computers into a central system usually the server over a particular network or the internet.
This central system usually called “the server” share computer and other related resources. The working principle of a client-server architecture requires that for communication to be archived, all communicating devices must be connected to the same network.
Client-Server Architecture Characteristics
- The client-server is characterized by its ability to coordinate programs in an application.
- The server provides on-demand services to clients.
- The resource sharing and information transfer in a server make a service.
- Client-server systems require a vast amount of hardware and software resources.
- A client or server application interacts directly with a transport layer protocol to establish communication and to send or receive information.
- The transport protocol then uses lower layer protocols to send or receive individual messages. Thus, a computer needs a complete stack of protocols to run either a client or a server.
Advantages Of Client-Server Architecture
Often time, organizations see the need to maintain and keep improving upon quality service delivery with the help of technology. Hence, deploying client-server computing will yield increased productivity by using cost-effective user-friendly interfaces, advanced data storage, increased connectivity, and reliable applications.
Here are a few advantages of implementing a client-server architecture:
- Integration of Services: Clients have access to their organization information with the help of a desktop application interface.
- Resource Sharing Across Platforms: Client-server applications are built to not have restrictions on the hardware platform or technical background of the entitled software (Operating System) by providing an open computing environment.
- Improved Data Sharing: Data retention by business processes is manipulated on a server is made available for clients with authorized access.
- Data Processing capability: This is a time were machine-centred systems transform user-centred systems. Machine-centred systems like mainframe, mini and micro applications had unique access platforms and functionality keys, navigation options, performance, and security were all visible.
- Security: Data privacy and protection is a watchword for any organization. Servers have quite several better control accesses and resources to ensure only authorized clients can access and or manipulate data.
- Easy to Maintenance: Client-server architecture is a distributed model with different responsibilities among independent computers connected across a network, it makes maintenance easy. Replacement of components, repair, upgrade, and relocating a server while clients remain unaffected can be archived.
Disadvantages Of Client-Server Architecture
- Server Overloading: Frequent client requests cause server overloading, forming traffic congestion.
- Centralized architecture: Since its centralized, if a critical server fails, client requests are not accomplished, hence network failure.
- The cost of setting up and maintaining a client-server model very high.
