Project Background: the ratio of reading to writing is about. the number of users is more than one million, and the concurrency is about 4000 (high or low, high to 10 K, and low to 1 K) the performance of several servers is almost the same, and load balancing can basically be evenly distributed to each server. I want them to directly one to one through load balancing... project background: The ratio of reading to writing is about. the number of users

What is the difference between a Web server, an application server, and an HTTP server? What kind of server does IIS, Apache, Tomcat, Weblogic, and WebSphere belong to? This concept is important.The basic function of Web server is to provide Web information browsing service. It only supports HTTP protocols, HTML document formats, and URLs. Mates with the client's browser. Because the Web server primarily supports protocols that are HTTP, HTTP servers

Web servers and ApplicationsProgramWhat are the differences between servers and HTTP servers? Which server does IIS, Apache, tomcat, WebLogic, and WebSphere belong to? these problems have been confusing for a long time. Today, we have finally sorted them out: The basic function of a Web server is to provide web information browsing services. It only supports th

In web development, you often hear Web servers (Web server), Web containers (Web Container), application servers (application server), reverse proxy servers (Reverse proxies) Server) can be confusing and difficult to understand nouns. In the interview, this is also often asked. This paper introduces the understanding, difference and connection of the four people.

In the process of learning the front end. Process to hear and see the Web server, HTTP server, application server, but always do not know what the difference between them, puzzled for a long time, today, many of the blog read, finally sort of comb through, I will summarize their differences, shun do not know some servers.First we need to know that the Web server only supports HTTP protocols, HTML document formats, and URLs.

the Red Flag Linux system is released when it is announced to be compatible with the RPM package, and in the red flag provided by the tool CD, I see a lot of packages are Rhel 4, so you can determine, Red Flag Linux can at least support the RPM package in Rhel 4. If you're using an RPM package, it's easy to install, and it's annoying that servers and client and other libraries are packaged separately and downloaded. And I downloaded a single compres

Web ServerWeb servers are generally divided into two types: Dynamic and Static. Static web pages are usually stored on servers by combining texts and images. They usually do not change much. Using two CPUs and One gigabit Nic can easily meet extremely high click rates. When a server uses a dual-processor, it can fully meet the requirements of thousands of clicks per second. It can also be used for large-sca

1. When data is exchanged between the client and the domain controller, each client occupies about 400-K of system resources, that is, about computers in SMT are added to the domain, therefore, when a policy is applied to the client, the system allocates the following resources to the client: 400*400 K or 200 * K, which may be between-M, although the probability of applications to each client at the same time is small, the domain controller should have the function and stability to process data

In layman's words, Web server delivery pages allow the browser to browse, whereas the application server provides a method (methods) that the client application can invoke (call). To be exact, you can say that the Web server is dedicated to HTTP requests (request), but the application server is providing (serves) business logic for the application through a number of protocols. 1. The application server processes the business logic, and the Web server is primarily for the customer to access thro
