What is Web Hosting
Providing access to websites and storage space to individuals and companies who own websites is known as web hosting. This Internet hosting service allows organizations and individuals to make their sites accessible on the World Wide Web. The service also allows organizations and individuals to provide content on their websites. A company that provides space on a server is called a web host. This host can own or lease the server to provide space on the website and to provide Internet connectivity such as a data center. Web hosts also practice colocation, this is where they provide data center space within their data center as well as Internet connectivity for servers they don’t own.
Typically a company will provide basic hosting services, however bundled packages have been made available for subscribers in recent times. Therefore, in addition to offering basic web hosting services, a company can also offer Domain Name System (DNS) hosting, this is a service that would be included in a domain name registration offer. The company can also offer an email hosting service in its bundled packages.
By uploading via File Transfer Protocol (FTP) or a web interface, a web host will be able to provide basic services such as small-scale file and web page hosting. With this service there is little or no modification to the files that are delivered to the web, they are usually uploaded as is with little or no processing. The basic service is usually offered free of charge by Internet Service Providers (ISPs) to subscribers. But subscribers also have the option to access web page hosting from other service providers if they wish. While a complex site, such as one that will provide support for database and application development platforms, will require more comprehensive web hosting packages, such as ColdFusion, Java, Ruby on Rails, ASP.Net, and PHP, personal web pages only require the single page hosting.
The direction in which data can be transferred, from a client to a server, and the speed at which it is needed to load the information is known as upstream. Although upstream speeds are generally higher as they are required by web server applications and similar processes to send critical data at a high speed. Downstream speed is usually required by the average Internet home user to download information, and usually doesn’t need to be fast. Except for peer to peer software, which are applications that allow computers to network or communicate with no stable host in between. This application that now drives social networks and facilitates file sharing systems, requires speed in downloading information การพนันที่ดีที่สุด
The amount of time a user has access to the Internet is known as uptime. Most providers aim for three quarters of an hour of downtime in a month or less – in other words, their goal is around 99.9% uptime. Of course there is always the planned or unplanned maintenance time that can occur in any hosting environment. This disruption of Internet user’s online time may not be included in the stated promise of uptime, the host provider’s service level agreement (SLA). Fortunately, some vendors will include a certain amount of uptime guarantee in their service level agreement, which will include money back or reduced cost if the promised uptime goal is not met.
