What does IIS mean, what is the number of IIS connections

IIS is an abbreviation for Internet Information Services and is a world Wide Web server. Gopher server and FTP server are all contained inside. IIS means that you can publish Web pages, and have ASP (Active Server pages), JAVA, VBScript-generated pages, and some extended functionality. IIS supports something interesting, such as an interface with an editing environment (FRONTPAGE), a IIS7 full-text search (INDEX SERVER), and Multimedia (NET show), followed by IIS as a Windows NT server 4.0 file and application servers provided together are basic components for establishing an Internet server on a Windows NT server. It is fully integrated with Windows NT Server, allowing the use of Windows NT Server built-in security and the NTFS file system to build powerful, flexible internet/intranet sites. IIS (Internet Information Server, Internet Information Service) is a Web (Web page) service component that includes Web servers, FTP servers, NNTP servers, and SMTP servers for Web browsing, file transfer, News services and mail delivery, which makes it easy to post information on the Web, including the Internet and the local area network.

The number of IIS or Web connections refers to the access requests that the server can respond to at the same time, and can be simply understood as allowing the number of browser windows to access your site simultaneously, for example: 100 IIS connections can have 100 browser windows connected to the server at the same time.

Reducing pop-up windows is an effective way to improve the number of online people, and also pay attention to other sites as a friendship connection as far as possible do not call the site code or pictures.

For general Web sites, basically in the same browser window to link access, rarely use pop-up windows, a visitor is only a number of IIS connections.

All IIS-based Windows class servers have a limited number of simultaneous connections, and too many connections will directly cause the server to be unstable and out of line. Serious can also cause the server IIS process to break or even the entire operating system crashes. Linux servers are similarly similar.

It can be said that the number of IIS connections is the most direct performance of virtual host standards.

Note that the number of IIS connections is not the number of days visited, the number of IIS connections refers to the maximum number of responses at the same time, for example, the number of IIS connections is 60, which means that the maximum number of requests in response to a second or so is 60, web site visits are much larger, if the number of visits is more average, daily visits can exceed thousands of, Even tens of thousands.

Normally 50 IIS guarantees 25-40 people to be online at the same time. For some programs like forums and communities, visitors usually open 2-3 windows and 150 IIS to ensure that 50-75 people are online at the same time.

Let's say you have 10,000 independent IPs for your day visit, how many IIS numbers are appropriate? This depends on the visitor's access time distribution is more balanced, how to be more balanced, then the station needs about 200IIS enough (except for the forum), if your site access is not balanced, then recommend you to upgrade the virtual host or purchase the server. Almost all of the virtual hosts are IIS restrictions, there is no IIS restrictions, but also CPU occupancy or traffic restrictions, while the attention: buy space is not without IIS restrictions on the space is good, to consider from many aspects.
