A web hosting service is a type of Internet hosting service that enables individuals and organizations to make their websites accessible via the World Wide Web by providing them with a web server. The term “web host” refers to a company that provides clients with space on a server that they own or lease, as well as Internet connectivity, which is typically provided in a data center. Web hosts can also provide data center space and Internet connectivity to other servers that are housed in their data center, a service known as colocation in Latin America and France, and also known as housing in the United Kingdom.
There are various types of hosting.
Web hosting service for a group of people
It is possible to have one’s website hosted on the same server as hundreds or thousands of other websites, depending on the server configuration. In most cases, all domains may share a common pool of server resources, such as RAM and the CPU, with one another. The features that are available with this type of service can be quite basic, and the software and updates that are available are not always up to date. Resellers frequently sell shared web hosting, and web companies frequently have reseller accounts in order to provide hosting for their customers.
Web hosting for resellers
Clients are given the option to become their own web hosts. The hosting types listed above could be used by resellers for individual domains, and the combination of hosting types used could vary depending on the company with which they are affiliated as a reseller. Resellers’ accounts can range in size from having their own virtual dedicated server to having a colocated server, and everything in between. Many resellers offer a service that is nearly identical to their provider’s shared hosting plan, and they also provide technical support for their customers.
Virtual Dedicated Server (also known as VDS)
A Virtual Private Server (VPS), also known as a virtual server, is a server that divides its resources into virtual servers, where resources can be allocated in a way that does not directly reflect the underlying hardware. VPS will frequently be assigned resources based on a one server to many VPSs relationship; however, virtualisation may be performed for a variety of reasons, including the ability to move a VPS container between servers, as discussed above. Users may have root access to their own virtual space if they so choose. Customers may be responsible for patching and maintaining the server (if it is an unmanaged server), or the VPS provider may perform server administration tasks on the customer’s behalf (if the server is managed) (managed server).
Dedicated hosting services are available.
In most cases, the user receives his or her own Web server and gains complete control over it (the user has root access for Linux and administrator access for Windows); however, the user does not typically own the server. Self-managed or unmanaged dedicated hosting is one type of dedicated hosting. For dedicated plans, this is typically the least expensive option. In addition, the user has complete administrative access to the server, which means that the client is solely responsible for the security and upkeep of his or her own dedicated server.
Managed hosting services are available.
In exchange for obtaining their own Web server, users are not granted complete control over it (for Linux, users are not granted root access/administrator access in Windows); however, they are permitted to access and manage their data remotely via FTP or other remote management tools. Users are denied complete control over the server in order to allow the service provider to ensure quality of service by not allowing users to modify the server or potentially cause configuration problems. In most cases, the server does not belong to the user. The server is rented out to the customer.
Service for web hosting in a colocation facility
Similar to dedicated web hosting, but the colo server is owned by the user; the hosting company provides the physical space that the server occupies and is responsible for the server’s maintenance and repair. This type of web hosting service is the most powerful and most expensive available. Colocation providers typically provide little to no direct support for their clients’ machines, instead focusing on providing only the necessary electrical, Internet, and storage infrastructure for the server to function properly. In the majority of cases, the client would send his or her own administrator to the data center to perform any necessary hardware upgrades or modifications on site. However, most colocation providers now require rack mount enclosures and standard system configurations for hosting, as opposed to the past where many would accept any system configuration for hosting, including those housed in desktop-style minitower cases.
Cloud computing is a type of computing where data is stored in the cloud.
Customer’s can benefit from a new type of hosting platform that provides them with highly scalable and reliable hosting that is based on a cluster of load-balanced servers and utility billing. Because other computers in the cloud can compensate when a single piece of hardware fails, a cloud-hosted website may be more reliable than other alternatives. Furthermore, because cloud hosting is decentralized, local power outages or even natural disasters are less of a concern for cloud-hosted sites. Cloud hosting also allows providers to charge users only for the resources that they consume, rather than charging a flat fee for the amount of resources that the user anticipates they will consume or charging a fixed cost for the hardware up front. Alternatively, a lack of centralization may result in users having less control over where their data is stored, which may pose a problem for those who have data security or privacy concerns, as defined by the General Data Protection Regulation. Clients of cloud hosting services can request additional resources on-demand (e.g., for use only during periods of high traffic volume), while offloading IT management to the cloud hosting service.
Hosting on a clustered server
It is preferable to have multiple servers hosting the same content in order to maximize resource utilization. Clustered servers are an excellent solution for high-availability dedicated hosting, as well as for building a scalable web hosting solution for large websites. A cluster may be configured to separate web-serving capability from database-hosting capability. (Typically, web hosts use clustered hosting for their shared hosting plans because there are numerous advantages to managing a large number of clients.)
Grid hosting is a type of cloud computing.
This type of distributed hosting occurs when a server cluster behaves like a grid and is made up of a number of different nodes.
Home server is a computer that is used at home.
Typically, a single machine located in a private residence can be used to host one or more web sites using a consumer-grade broadband connection, which is common in most cases. These can be either custom-built machines or, more commonly, old personal computers. Some Internet service providers (ISPs) actively attempt to block home servers by disallowing incoming requests to TCP port 80 of the user’s connection and by refusing to provide static IP addresses to customers. A common method of obtaining a dependable DNS host name is to sign up for a free account with a dynamic DNS provider. The IP address that a URL points to will be automatically changed by a dynamic DNS service if the IP address of the server changes
