Web hosting

The web host (in English web hosting ) is the service that provides users of Internet system to store information, images, video, or any content accessible via the web. It is an analogy of “lodging or hotel accommodations or rooms” where one occupies a specific place, in this case the analogy hosting or Web hosting refers to the place of a web page, web site , system, email , files etc. on internet or more specifically on a server that usually hosts multiple applications or web pages.

The companies that provide space on a server to its clients are often referred to the English term web host .

The web hosting although not necessarily a service, has become a lucrative business for Internet companies around the world.

It can be defined as “a place for your website or emails,” though this definition simplifies conceptually the fact that web hosting is actually space on the Internet for virtually any type of information, either file systems, emails , videos etc.

Types of web hosting on the Internet

Depending on the specific needs of a user, there are different types of web hosting one among which the user must choose according to their needs. The main types of web hosting are:

Free hosting

Free accommodation is extremely limited compared to paid hosting. These services usually add advertising sites in addition to very limited resources (disk space, data traffic, CPU usage, etc).

A free web hosting (also known as free hosting ) is a service that allows users to publish web sites for free.

By registering for a service “free hosting” you typically get a control panel from which you can manage the service and a URL from which you can access the site.

There are a variety of sites and companies that provide services for “free web hosting”, each have their peculiarities in the type of service provided and the conditions thereof.

Shared hosting

n this type of service customers are staying several sites on the same server, by configuring the web server program . It is very good for small and medium customers alternative is an affordable due to reduced costs and that sharing a server with hundreds or thousands or millions users the cost for each is drastically reduced, and has good performance.

The disadvantages of this type of web hosting should be mentioned especially that share the resources of hardware of a server hundreds or thousands of users significantly decreases the performance of the same. It is also very common that a user failures due to impact on others so the server administrator must take extreme caution when assigning writing and execute permissions to users. In summary, the disadvantages are: reduction in server resources, speed, performance, security and stability.

Free Image Hosting

This type of accommodation is offered to save images on the internet, most of these services are free and pages worth of advertising placed on your page to upload the image.

Reseller hosting

The reseller hosting is a type of web hosting in which hosting plan within a server allows resell hosting account within the same plan, allowing to create subdomains and add domains external, creating subplans or hosting plans within the account reseller hosting. These services can be very convenient for designers of web pages .

This hosting service is designed for heavy users or people who sell hosting service to others. These packages have a lot of space and domains available for each account. Also these spaces are limited capacity and domains hosted clients and therefore requires a dedicated server search.

Virtual Servers ( VPS, Virtual Private Server )

It is known as virtual server to a partition within a server that enables multiple virtual machines within the machine through various technologies .

The company offers the control of a computer apparently not shared, which is performed by a virtual machine . So you can manage multiple domains easily and economically, in addition to choosing the programs that run on the server. Therefore, it is recommended for the type of business product design and web programming.

The virtual dedicated servers (VDS) technology using advanced virtualization , which allows you to provide access [root] and the ability to restart when you want, like a dedicated server. With the ability to install their own applications and fully control the configuration of your server, the SDV represent an economical and efficient for those who want to enjoy the benefits of a dedicated server but do not yet have the budget to do alternative.

Each SDV is assigned a limit on the use of CPU and RAM (among others) that is dedicated only from within the server. Thus, each of the SDV function independently within the same physical server; is acting as cages within the same team. For example, if one of them is badly managed and works as overloaded, will not affect the operation of the rest.

In contrast, in a hosting shared (both reseller and individual) server resources are shared among all accounts “hosting” that is in it, and if there is a problem perhaps overload generated by the abuse of one domain — the performance of the “hosting” will be overloaded on all equipment; that is, on all accounts.

It is known as virtual server SPEC (Server Cluster environment elite) to a solution aimed specifically at the professional sector and, in some cases, the client finally, allowing virtually manage and optimize server resources through the use of a powerful infrastructure redundant , clustered and ability to mount VPN . Sets systems or applications, support any type of service and determine how to develop and define.

If you need to host multiple web sites, a Virtual Private Server (VPS) is the most economical option. You can host numerous websites on a VPS without the costs of having to buy their own separate physical server.

Dedicated servers

A dedicated server is a computer purchased or leased used to provide dedicated services, usually related to web hosting and other network services. Unlike what happens with shared hosting, where machine resources are shared between any number of clients, in the case of dedicated servers, generally is one client that has all the resources of the machine for the purposes for which it has contracted the service.

Dedicated servers can be used to serve both shared hosting to dedicated hosting services, and can be managed by the customer or the company that provides them. The physical care of the machine and Internet connectivity is generally in charge of the company that provides the server. A dedicated server is usually located in the data center .

A dedicated server can be seen as the counterpart of the shared web hosting, but that does not mean that a dedicated server can not be adapted to deliver this type of service. This is the case when, for example, a company engaged in the business of web hosting purchase or lease a dedicated server with the objective of providing web hosting services to its customers.

Furthermore, a dedicated server can be used as an advanced form of web hosting company when a customer has special requirements or performance, configuration or security. In these cases it is common for a company to lease a dedicated server to supply themselves with the services you require having all the resources of the machine.

The main disadvantage of a dedicated server is the cost of service, which is much higher than the shared hosting. This is due mainly to the monthly cost of the machine and the need to engage the services for the administration and server configuration.

Managed and Unmanaged Hosting

Some companies offer their customers better prices if they hire a hosting plan “Unmanaged” this means that they are limited to provide the connectivity, resources, control panel and all necessary tools to manage the contracted plan but will not provide assistance for bugs, misconfigurations or errors caused by the web application being executed (CMS, PHP files, HTML) which must be managed entirely by the webmaster of the website.

In the “Managed Hosting” usually carries a higher price but the support includes a certain amount of incidents / times in the span of a month or a year depending on the contract plan and you can request help to remedy problems in their scripts, errors execution or similar.

Cloud Hosting

Web hosting in the “cloud” ( cloud hosting ) is based on the most innovative technologies that allow a large number of machines to act as a connected to a media storage system has considerable advantages over solutions web hosting traditional such as the use of resources. The security of a web site hosted in the “cloud” ( cloud ) is guaranteed by many servers instead of just one. The technology of cloud computing also eliminates any physical limitations to growth in real time and makes the solution extremely flexible.
