Web hosting is a service that provides Web users with online systems for storing information, images, video, or any content accessible via the web. Web hosts are companies that provide space on a server they own for use by their clients.
The type of hardware, security, high-speed internet connections and physical housing requirements required to reliably serve web content and email necessitate the storage of client content on servers in secure data rooms with redundancy and power backups. Therefore web hosting is usually offered by companies who rent out space on their servers to customers.
You can transform your business to a revenue-producing asset that lets you work as much or as little as you want.
- Repeatable business process-led services shared among several clients
- Remotely delivered application services using shared resources
- Infrastructure services (both remotely managed and/or hosted services spanning data center services, managed servers and databases, performance monitoring, security services, storage services and business continuity)
- Web hosting- the provision of infrastructure and application services to support the hosting of Web sites.
The most basic is the web page and small-scale file hosting, where files can be uploaded via File Transfer Protocol (FTP) or a Web interface. The files are usually delivered to the Web “as is” or with minimal processing. Many Internet service providers (ISPs) offer this service free to subscribers. Individuals and organizations may also obtain Web page hosting from alternative service providers.
Free web hosting service is offered by different companies with limited services, sometimes supported by advertisements, and often limited when compared to paid hosting.
Single page hosting is generally sufficient for personal web pages. Personal web site hosting is typically free, advertisement-sponsored, or inexpensive. Business web site hosting often has a higher expense depending on the size and type of the site.
Many large companies that are not Internet service providers need to be permanently connected to the web to send email, files, etc. to other sites. The company may use the computer as a website host to provide details of their goods and services and facilities for online orders.
A complex site calls for a more comprehensive package that provides database support and application development platforms. These facilities allow customers to write or install scripts for applications like forums and content management. Also, Secure Sockets Layer (SSL) is typically used for websites that wish to keep the data transmitted more secure.
the user gets his or her own Web server and gains full control over it (user has root access for Linux/administrator access for Windows); however, the user typically does not own the server. One type of dedicated hosting is self-managed or unmanaged. This is usually the least expensive for dedicated plans. The user has full administrative access to the server, which means the client is responsible for the security and maintenance of his own dedicated server.
Reliability and uptime:
The availability of a website is measured by the percentage of a year in which the website is publicly accessible and reachable via the Internet. This is different from measuring the uptime of a system. Uptime refers to the system itself being online. Uptime does not take into account being able to reach it as in the event of a network outage.A hosting provider’s Service Level Agreement (SLA) may include a certain amount of scheduled downtime per year in order to perform maintenance on the systems. This scheduled downtime is often excluded from the SLA timeframe and needs to be subtracted from the Total Time when availability is calculated. Depending on the wording of an SLA, if the availability of a system drops below that in the signed SLA, a hosting provider often will provide a partial refund for time lost. How downtime is determined changes from provider to provider, therefore reading the SLA is imperative.
