What does distributed architecture mean in php

In PHP, the distributed architecture refers to multiple servers processing different tasks, storing data dispersedly on multiple independent machines and devices, and using multiple storage servers to share the storage load and improve the reliability of the system. performance, availability and scalability.

What is the meaning of distributed architecture in php

What are the specific implementation methods of distributed structure in php? This is worth discussing. .

for example. For example, if you have a complete system, the system has several large modules. Generally, a small plan is to have several small modules on the same WEB server. Then when PV and UP come up, the pressure will be unbearable. Then you can do appropriate splitting. One module has one server, and the RPC framework is used between modules to share data. Distributed can be summed up in one sentence, split on the premise of ensuring data sharing throughout the system. There are also concepts of differentiation, distribution and load balancing.

Distributed is a solution that has nothing to do with language

Distributed network storage technology is to store data dispersedly on multiple independent machines and devices. The distributed network storage system adopts a scalable system structure, uses multiple storage servers to share the storage load, and uses location servers to locate storage information. This not only solves the bottleneck problem of a single storage server in traditional centralized storage systems, but also improves the reliability of the system. performance, availability and scalability.

php distributed refers to multiple servers processing different tasks, which refers to general business. For example, some processing logs of multiple servers are distributed to some servers, and some process orders and are distributed to some servers. .

As a guarantee of collaborative development specifications and development efficiency, the framework has to be introduced into daily development. However, once the framework is added, it will inevitably affect the overall performance of the PHP interface.

The performance of php code based on php7 swoole has surpassed the statically compiled go language.

Laravel, the currently popular PHP framework, has indeed solved many standardization and development efficiency issues; however, its bloated architecture and encapsulation implemented in PHP have made its performance poor.

In view of this situation, this architecture chooses the c extension framework phalcon as the development framework to minimize the performance loss caused by the framework.

After deploying using the Web cluster method, the first thing to adjust is the user status information and attachment information. The user status can no longer be saved to the Session, the cache cannot use the file cache of the local Web server, and the attachments cannot be saved on the Web server.

Because it is necessary to ensure that the status of each web server in the cluster is completely consistent. Therefore, user status, cache, etc. need to be saved to a dedicated cache server, such as Memcache. Attachments need to be saved to cloud storage.
