Relationship Parent process, child process 2.4 Process Management-related system calls This section discusses the implementation of the fork and Exec series system calls. Usually these calls are not emitted directly by the application, but rather through a middle-tier call, the C standard library that is responsible for communicating with the kernel. The way to switch from a user state to a kernel mentalit

The basic architecture of Linux is summarized by the following two graphs (two graphs are the same, but the focus is slightly different)From the knowledge, Linux is composed of two parts: User space and kernel space. Kernel space and user space are two different states of program execution, which can transfer from user space to kernel space through system call and hardware interrupt.Due to the different ver

Recently responsible for a project's system architecture design, just started rough to give a draft. After a revision with a draft to find the company's chief scientist legend of "God", a long talk, although criticized for nothing, but I feel unusually cool, suddenly feel that in the system architecture design has grad

Generally, you can use two methods. If you can do business load balancing, you can use Server Load balancer to implement the cluster and then monitor each serve

In the process of expanding the size of Web websites from small to large, the database access pressure is constantly increasing, and the database architecture needs to be dynamically expanded, the database expansion process consists of the following steps. Each extension can improve the performance of the deployment method in the previous step by an order of magnitude. 1. web applications and databases are deployed on the same server. Generally, small

Currently, cache is widely used in website architecture to provide the performance of Web applications. The following types of cache architectures exist for different websites. (1) Single-host Cache (2) Simple distributed cache (3) cache cluster Using Replication (4) cache cluster using hash (5) high-performance, high-reliability cache Cluster The following is a detailed analysis of the applicability and advantages and disadvantages of the above cache

purpose of the flow queue data is to determine the data in the table where the data will be keptis insert,update and delete, and each operation generates the corresponding log information. In MySQL, if theThe storage engine that holds the transaction, the amount of this log generation is doubled. And if we go through some mature third-party queue software toThe performance of this queue data processing function will be multiplied.3.

-oriented programming. In fact, this concept was put forward a long time ago, but it is not widely used. It is quite confusing, I usually use Relatively small. However, we are very useful in the system architecture, especially in the process of separation of concerns. The main purpose of AOP is to combine the cross-cutting concerns with the core layered form or Feature component separation. Next we will
