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

Differences between WEB servers, application servers, and HTTP servers What are the differences between WEB servers, application servers, and HTTP servers? Which server does IIS, Apache, Tomcat, Weblogic, and WebSphere belong to?

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 main function is to transfer the page so that the browser can browse

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

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

The essentialThe key to high-performance network servers is concurrency, how to use multi-core servers efficiently, and allow multiple threads to process programs concurrently.concurrency mode Time-based parallelism Space-based parallelism, Other references, Within the computer, the most essential is the time (CPU) and Space (memory) of the two resources, the various parallel boundarie

larger queue length of 65536, which can accommodate the maximum number of network connections waiting to be connected.Net.ipv4.tcp_max_syn_backlog = 65536When a network card receives a packet that is faster than the kernel processing speed, a queue holds the packets. This parameter represents the maximum value of the queue. Default is 1000Net.core.netdev_max_backlog = 32768The default parameter of Listen (), the maximum number of pending requests. The default is 128. For busy

First, the setting of dedicated servers is very simple ----- You do not need to set it. This is the default option of Oracle. For shared servers, you need to make some additional settings. It is not difficult to follow the administrator guide. The key is that you need to decide how many shared s

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

The most widely used free HTTP server on UNIX and Linux platforms is the universal, NCSA, and Apache servers, while the Windows platform nt/2000/2003 uses IIS Web servers. Some of the most common Web servers you should consider when choosing to use a Web server are performance, security, logging and statistics, virtual hosts, proxy

Microsoft®sql Server? 2000 supports distributed queries by using OLE DB (Microsoft Universal Data Access Application Interface (API) specification).Does the linked server configuration allow Microsoft®sql server? Executes commands against OLE DB data sources on other servers. Linked servers have the following advantages:Rem

request is sent to the Web server, it simply passes the request to a program that can process the request well: server scripts ). The Web server only provides an environment that can execute the server-side program and the response generated by the program. Server-side programs generally have functions such as transaction processing, database connectivity, and messaging. Although the Web server does not support transaction processing or database connection pools, it can configure various strate

How to make Linux servers more secure and linux servers more secureI run several Linux servers. I have one at home, serving as a file server, and three active servers used as my Site Server, email server, and cloud storage server.

Use PSSH to batch operate Linux servers and psshlinux serversIntroduction When there are more servers, one problem is how to quickly operate multiple servers in batches. I found the PSSH tool on the Internet. I tried it and found it useful. I recommend it to you. Pssh is a lightweight management tool written in python that can execute commands on multiple

WebLogic domain, Management Server, managed server, cluster and Machine Basics 1. Domain? What is it? – is a logically managed WebLogic server group that is managed as a whole? What's in the domain? – Server – Server cluster – machine? Rule: – All WebLogic server instances in the same domain must be in the same version. – Servers in a domain can be at different levels of maintenance packages as long as the Management Server is in the same maintenance
