What does b/s architecture mean?

With the continuous development of Internet technology, various network architecture models continue to emerge. Among them, the B/S architecture is the more common one. The full name of B/S architecture is Browser/Server architecture, which means browser/server architecture in Chinese. It is a web browser-based client/server architecture.

In the B/S architecture, the user uses the browser to send a request to the application server through the Internet. After receiving the user's request, the server returns data in the form of various HTML web pages to the browser, and sends various control commands to the browser through JavaScript language (such as input format verification, internal page references, dynamic interface refresh, implementation of asynchronous requests, etc.) . After the server performs logical processing on the operation, it returns the results (such as data added, deleted, modified, and checked) to the browser client.

The characteristics of the B/S architecture are: the browser is the client, which completes various functions through interaction with the server; the server is the server, which is responsible for receiving and processing the client's request and returning the request result. This model is a typical client/server model. In the B/S architecture, the browser client does not need to install any software, as long as it can connect to the Internet, while the server needs to have data processing capabilities, access rights and network resource management capabilities.

In terms of advantages, the reason why the B/S architecture is more popular is that it can be cross-platform and cross-browser. This means that the client and server ports do not need to be paired, and one port can be used by multiple users at the same time. . In addition, the B/S architecture can effectively reduce the client resource occupation pressure of the application and reduce the machine load. Another point is that the B/S architecture can provide enterprises with more stable and reliable services, which is one of the reasons why major enterprises pursue this architecture.

In terms of shortcomings, the B/S architecture also has its limitations. Because it is based on the HTTP/HTTPS protocol, the speed is relatively slow, and some application scenarios with strong real-time performance require more efficient data transmission protocols, such as TCP/IP, UDP, etc. In addition, the B/S architecture has relatively high requirements on the hardware environment of the client and server, as well as high bandwidth and performance requirements.

Generally speaking, the B/S architecture is a relatively mature network architecture model, which is conducive to the construction of internal information system platforms for enterprises and institutions, and is suitable for the construction of large-scale application systems, such as ERP, CRM systems, etc. In the field of Web applications, the B/S architecture is also one of the most important architectural patterns.
