Model Client Server what is? Pros, cons and benefits when business apps

In the age of technology development, the enterprise increasingly depends on network systems to optimize operations, data management, connect the parts. One of the network architecture is use today's most popular model is Client Server, play an important role in the operation and management system.

This article will help you understand about Client Server what is? How it works, Pros and cons – benefits and practical application. If you are looking for network solutions suitable for deployment in business, this document is not to be missed.

1. Model Client Server what is?

1.1 Workflow Definition

Model Client Server is a network architecture in which the device is called Client (client), send the request to one or more Server (server) to handle and feedback. Server responsible resource management, providing services for the Client, creating a system that works efficiently sync.

Practical example: In a business, the computer of the employee (Client) can access the server data store (s) Server to retrieve information or handle the job.

1.2 The main components

Client (client):

• Role: device Client send request (Request) to the Server to retrieve information, access resources, or perform tasks.
• Mission: Send data request; Displayed results are returned from the Server.

Server (server):

• Vai trò: Server là trung tâm xử lý và lưu trữ dữ liệu, đáp ứng yêu cầu từ Client.

1.3 The mechanism of action of the model Client Server

The relationship between Client and Server: Client sends request via network protocols, such as HTTP, FTP, or SQL. Server received request, information processing, returns the result.

Process request and response (Request-Response):

• Step 1: Client sends a request to the Server, for example, requires access to the document.
• Step 2: Server receives the requests, handle, retrieve necessary data.

2. The model type Client Server popular

Model Client Server to be deployed in many different ways to suit the scale and needs of each business. Here are three types of most popular model along with the application characteristics.

2.1. Model Client Server 2 floors

Characteristics

• The most simple model in the Client Server architecture.
• Client to communicate directly with the Server, no intermediate floors.
• Data is stored and processed in the Server, while the Client only performs duties shown, send a request.

Benefits

• Easy to deploy:in accordance with the system of small business have less users. Duration fast installation, lower cost model more complex.
• High performance: connect directly help reduce latency when transferring data between Client and Server.

Restrictions

• Scalable low: When the number of users increases, the Server vulnerable to overload.

Application: The system data management as simple as management system, library or software, internal accounting.

2.2. Model Client Server 3 floors

Characteristics

• Includes three tiers: Client, middle tier (middleware), Server.
• Intermediate floors role logic processing app, helps reduce the load on the Server.

Benefits

• Higher security: the intermediate Floor helps to control encryption of data, limiting the risk of attack from the outside.
• Scalability: easily upgrade each tier without affecting the entire system.
• Separate tasks: middle Tier handles logic, Server centralized data storage, Client only displays information.

Restrictions

• More complex in implementation: request time greater cost to design and build.
• Depends on the intermediate floors: If your floors this trouble, the entire system will be interrupted.

Application: the System of e-commerce, ERP software, or the application need to handle complex data.

2.3. Model Client Server multi-tier

Characteristics

• Is the expansion of model 3 storey building with many floors, such as adding floor, data analysis, or floor security.
• The tiers are clearly divided, assume each specific function.

Benefits

• Optimal performance: The task is clearly divided, helping to optimize handling, reduce the load for each floor.
• High flexibility: Easy to integrate new technology that does not affect the current system.
• Meet the best system for large: Suitable for large enterprise or system requires high performance and reliability.

Restrictions

• High investment costs: Requires infrastructure, powerful hardware and IT team has high expertise.
• Management complexity: Requires the maintenance process, regular monitoring to ensure all the active sync.

Application: The application, banking, insurance, or system service cloud scale.

Three types of model Client Server (2-tier, 3-tier, multi-tier) provides the right solution for each scale, different needs. While model 2-storey suited for simple systems, the model 3 floors, multi-floors back to better respond to complex applications, and large enterprises.

3. Advantages and disadvantages of network model Client Server

• Depends on the Server: If the Server trouble, the entire system could be disrupted. When the Server is hardware fault or hacked, Client can not access data or resources. Therefore, should implement measures to backup and system backup (backup and failover).
• The cost of the initial investment is high: Businesses need to invest in powerful hardware and specialized software for Server. The cost of buying servers, system settings, network, software, management Server may be higher than the model peer network (Peer-to-Peer). Use cloud services to reduce the cost of the initial investment.
• High technical requirements: To operate the system effectively, businesses need IT team have the experience to manage and maintain the Server. The network administrator must ensure the Server is always stable operation, which is updated timely.
