How to analyze the two major architectures of TCS and LCA of cloud storage? I believe that many inexperienced people do not know what to do about it. Therefore, this article summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

Cloud storage (Cloud storage) is a mode of online storage, that is, data is stored on multiple virtual servers, which are usually hosted by third parties, rather than on dedicated servers. The concept began with a service provided by Amazon. Traditional systems use tightly coupled symmetric architecture (TCS), and the next generation architecture has adopted loosely coupled asymmetric architecture (LCA). The information of the two architectures is as follows:

Tightly coupled symmetric Architecture (TCS):

The tightly coupled architecture is essentially a Client--Server model. The client initiates a request to the server, which responds to the request and then gives feedback to the client.

TCS architecture design is simple, the development cycle is short, and can be quickly deployed and applied. However, with the increase of data calculation and computing time, the tightly coupled architecture is gradually overwhelmed, and its shortcomings appear, mainly in the following aspects:

Unable to support large-scale computing business

The computer can not control the overload phenomenon, and the overload does great harm to the hardware, which will seriously reduce the stable operation ability and service life of the computer.

There is no control in the process of task execution, so it is difficult to manage.

The consumption of network resources is large, and a large part of the synchronization operation is idle between data transmission and data return, which is a great waste of network resources.

If the server is directly exposed to the client, it is easy to cause network attacks and the security control is poor.

The correlation between program codes is too high, which is not conducive to modular processing.

Loosely coupled asymmetric Architecture (LCA):

Loosely coupled asymmetric Architecture (LCA) architecture adds an Agent between the original Client--Server models to turn the CS model into a CAS model. In the new architecture, the role of the client remains the same, and the proxy server is responsible for communicating with the client and identifying and judging the client. the server is located behind the proxy server and is invisible to the client. It is only responsible for data processing.

The ability of multitasking parallel processing has been greatly improved.

Realize the load adaptive mechanism, assign parallel tasks according to the running environment and loosely coupled architecture, and avoid overloading.

The random control of running tasks is realized, and the loosely coupled architecture randomly adjusts and controls the running tasks to avoid continuous overload.

Basically put an end to network attacks, due to the isolation and screening role of the proxy server, combined with other security management means, external attacks are identified and filtered out at the proxy server.

Conducive to the realization of complex data business processing

Asynchronous operation reduces network resource consumption and operation correlation.

Enhance the stability of the system
