Web hosting is an Internet hosting service that allows individuals and organizations to make their websites accessible via the World Wide Web. Web hosts provide space on a server owned or leased for clients’ use and Internet connectivity, typically in a data centre. Web hosts can also provide data centre space and connectivity to the Internet for other servers located in their data centre, called colocation.

The most basic is 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 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. Personal website hosting is typically free, advertisement-sponsored, or inexpensive. Business website hosting often has a higher expense.

An individual or business look for hosting, which is secure, faster, and cheaper.

Types of service hosting

Free hosting service: offered by different companies with limited services, sometimes supported by advertisements, and often limited compared to paid hosting.
Shared web hosting service: one’s website is placed on the same server as many other sites, ranging from a few to hundreds or thousands. Typically, all domains may share a common pool of server resources, such as RAM and the CPU.

Reseller web hosting: allows clients to become web hosts themselves. Resellers could function for individual domains under any combination of these listed types of hosting, depending on who they are affiliated with as a reseller. Resellers’ accounts may vary tremendously in size: they may have a virtual dedicated or colocated server.

Virtual Dedicated Server, also known as a Virtual Private Server (VPS), divides server resources into virtual servers, where resources can be allocated in a way that does not directly reflect the underlying hardware. VPS will often be allocated resources based on a one server-to-many VPS relationship. However, virtualization may be done for several reasons, including the ability to move a VPS container between servers.

Dedicated hosting service: the user gets their Web server and gains complete control; however, the user typically does not own the server. Another 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, meaning the client is responsible for the security and maintenance of his dedicated server.

Cloud hosting is a new platform that allows customers to enjoy robust, scalable, and reliable hosting based on clustered load-balanced servers and utility billing. A cloud-hosted website may be more reliable than alternatives since other computers in the cloud can compensate when a single piece of hardware goes down. Also, local power disruptions or natural disasters are less problematic for cloud-hosted sites, as cloud hosting is decentralized.

Clustered hosting service: having multiple servers hosting the same content for better resource utilization. Clustered Servers are a perfect solution for high-availability dedicated hosting or creating a scalable web hosting solution. A cluster may separate web serving from database hosting capability.

Grid hosting service: this form of distributed hosting is when a server cluster acts like a grid composed of multiple nodes.

Apart from these service hosting, there are other service hosting like managed service hosting, File

hosting service: hosts files, not web pages, Image hosting service, Video hosting service, Blog hosting service, Shopping cart software, E-mail hosting service, etc.

Web hosting service is often provided as part of a general Internet access plan; many free and paid providers offer these types of web hosting.
