Service scope
The scope of hosting services varies widely. 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. A web page or webpage is a resource of information that is suitable for the World Wide Web and can be accessed through a Web browser. To download is to receive data from a remote or central system such as a Webserver, FTP server, mail server or other similar systems The files are usually delivered to the Web "as is" or with little processing. Many Internet service providers (ISPs) offer this service free to their subscribers.

They are commonly used by larger companies to outsource network infrastructure to a hosting company. To find a web hosting company, searchable directories can be used. One must be extremely careful when searching for a new company because many of the people promoting service providers are actually affiliates and the reviews are biased.
Hosting reliability and uptime
Hosting uptime refers to the percentage of time the host is accessible via the internet. Uptime is a measure of the time a Computer system has been "up" and running Many providers state that they aim for a 99. 9% uptime, but there may be server restarts and planned (or unplanned) maintenance in any hosting environment.
A common claim from the popular hosting providers is '99% or 99. 9% server uptime' but this often refers only to a server being powered on and doesn't account for network downtime. Real downtime can potentially be larger than the percentage guaranteed by the provider. Many providers tie uptime and accessibility into their own service level agreement (SLA). A service level agreement (frequently abbreviated as SLA) is a part of a service contract where the level of service is formally defined SLAs sometimes include refunds or reduced costs if performance goals are not met.

- Shared web hosting service: one's Web site is placed on the same server as many other sites, ranging from a few to hundreds or thousands. A shared web hosting service or virtual hosting service or derive host refers to a Web hosting service where many websites reside on one Web server Typically, all domains may share a common pool of server resources, such as RAM and the CPU. A shared website may be hosted with a reseller.
- 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 provider. Resellers' accounts may vary tremendously in size: they may have their own virtual dedicated server to a colocated server.
- Virtual Dedicated Server: dividing a server into virtual servers, where each user feels like they're on their own dedicated server, but they're actually sharing a server with many other users. A virtual private server ( VPS, also referred to as Virtual Dedicated Server or VDS) is a method of partitioning a physical server computer into multiple The users may have root access to their own virtual space. This is also known as a virtual private server or VPS.
- Dedicated hosting service: the user gets his or her own Web server and gains full control over it (root access for Linux/administrator access for Windows); 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 box, which means the client is responsible for the security and maintenance of his own dedicated box.
- Managed hosting service: the user gets his or her own Web server but is not allowed full control over it (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 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. A colocation centre ( collocation center) (" colo " or carrier hotel is a type of Data center where multiple customers locate network This is the most powerful and expensive type of the 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 own administrator visit the data center on site to do any hardware upgrades or changes.
- Clustered hosting: having multiple servers hosting the same content for better resource utilization. Clustered hosting technology is designed to eliminate the problems inherent with typical Shared hosting infrastructures Clustered Servers are a perfect solution for high-availability dedicated hosting, or creating a scalable web hosting solution.
- Grid hosting : this form of distributed hosting is when a server cluster acts like a grid and is composed of multiple nodes. Grid computing is a form of Distributed computing whereby a "super and virtual computer" is composed of a cluster of networked loosely-coupled
- Home server: usually a single machine placed in a private residence can be used to host one or more web sites from a usually consumer-grade broadband connection. A home server is a device typically a PC or other computer connected to a Home network that provides services to other devices in the Household. The term broadband can have different meanings in different contexts These can be purpose-built machines or more commonly old PC's.
Some 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. The Transmission Control Protocol (TCP is one of the core protocols of the Internet Protocol Suite. An Internet Protocol ( IP) address is a numerical identification ( Logical address) that is assigned to devices participating in a Computer network A common way to attain a reliable DNS hostname is by creating an account with a dynamic DNS service. A dynamic DNS service will automatically change the IP address that a URL points to when the IP address changes.
