* '''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 their own virtual dedicated server to a colocated server. Many resellers provide a nearly identical service to their provider's shared hosting plan and provide the technical support themselves.

* '''[[Virtual private server#Hosting|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 VPSs relationship, however virtualisation may be done for a number of reasons, including the ability to move a VPS container between servers. The users may have [[root access]] to their own virtual space. Customers are sometimes responsible for patching and maintaining the server (unmanaged server) or the VPS provider may provide server admin tasks for the customer (managed server).

* '''[[Dedicated hosting service]]''' – The user gets his or hertheir own web server and gains full control over it (user has [[Superuser|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 histheir own dedicated server.

* '''[[Managed hosting service]]''' – The user gets his or hertheir own web server but is not allowed full control over it (user is denied root access for Linux/administrator access for Windows); however, they are allowed to manage their data via FTP or other remote management tools. The user is disallowed full control so that the provider can guarantee quality of service by not allowing the user to modify the server or potentially create configuration problems. The user typically does not own the server. The server is leased to the client.

* '''[[Colocation center|Colocation web hosting service]]''' – Similar to the dedicated web hosting service, but the user owns the colo server; the hosting company provides physical space that the server takes up and takes care of the server. This is the most powerful and expensive type of web hosting service. In most cases, the colocation provider may provide little to no support directly for their client's machine, providing only the electrical, Internet access, and storage facilities for the server. In most cases for colo, the client would have his or hertheir own administrator visit the data center on site to do any hardware upgrades or changes. Formerly, many colocation providers would accept any system configuration for hosting, even ones housed in desktop-style [[minitower]] cases, but most hosts now require [[rack mount]] enclosures and standard system configurations.

* '''[[Cloud computing|Cloud hosting]]''' – Hosting based on clustered load-balanced servers. 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 even natural disasters are less problematic for cloud hosted sites, as cloud hosting is decentralized. Cloud hosting also allows providers to charge users only for resources consumed by the user, rather than a flat fee for the amount the user expects they will use, or a fixed cost upfront hardware investment. Alternatively, the lack of centralization may give users less control on where their data is located which could be a problem for users with [[data security]] or [[privacy policy|privacy]] concerns as per [[General Data Protection Regulation|GDPR]] guidelines. Cloud hosting users can request additional resources on-demand such as only during periods of peak traffic, while offloading IT management to the cloud hosting service.

* '''[[Clustered hosting]]''' – 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. (Usually web hosts use clustered hosting for their shared hosting plans, as there are multiple benefits to the mass managing of clients).<ref>{{Cite book |doi = 10.1109/HPCC.2008.172 |arxiv = 0808.3558|chapter = Market-Oriented Cloud Computing: Vision, Hype, and Reality for Delivering IT Services as Computing Utilities|title = 2008 10th IEEE International Conference on High Performance Computing and Communications|pages = 5–13|year = 2008|last1 = Buyya|first1 = Rajkumar|last2 = Yeo|first2 = Chee Shin|last3 = Venugopal|first3 = Srikumar|isbn = 978-0-7695-3352-0| s2cid=16882678 }}</ref>
