Some concepts of Web Hosting and DomainMCRS
A Web Hosting service is one that allows individuals and organizations (Internet users in general) to make their website accessible through the Internet. We can define a website as a set of related web pages capable of storing information, images, videos, or any content accessible via the web.
An Internet domain is a unique name that recognizes a website on the Internet. Domain names are governed by the rules and procedures of the Domain Name System (DNS) whose purpose is to translate the IP addresses of each node active in the network, to memorize and easy to find terms. Therefore, DNS is a system used to translate names in the network.
Types of web hosting
According to the specific requirements of a user, there are different types of web hosting among which the user has to choose the option that matches their needs.
The most basic website hosting service is only the webpage and smaller file hosting. With the File Transfer Protocol (FTP), the files are uploaded here, even sometimes with a web interface.
Free accommodation is extremely limited compared to paid accommodation. These services generally add advertising to the sites in addition to very limited resources (disk space, data traffic, CPU usage, etc.) and restrict access to service configurations. Some of the platforms that allow you to create a blog or web page for free are WordPress.com, Blogger.com, Wix.com, Weebly.com, etc.
The opposite case is the paid hosting service consisting of a contract with an Internet provider or ISP, which together with an Internet connection, makes available to the user a machine with storage to host your website.
The shared hosting allows hosting clients from several sites on the same server, thanks to the configuration of the web server program. It is a very good alternative for small and medium customers, it is an economic service due to the reduction of costs since when sharing a server with hundreds of thousands or millions of people or users the cost is drastically reduced for each one. As significant disadvantages, we can highlight the decrease in server resources, speed, performance, security, and stability.
There is also the Virtual Servers mode (Virtual Private Server, VPS) where the company offers control of a computer apparently not shared, which is done through a virtual machine. This way you can manage several domains easily and economically, as well as choosing the programs that run on the server.
A dedicated server is a purchased or leased computer that is used to provide dedicated services, usually related to web hosting and other network services. Unlike what happens with shared hosting, where the resources of the machine are shared among an undetermined number of clients, in the case of dedicated servers, it is usually a single client that has all the resources of the machine for the purposes for which you have contracted the service. Dedicated servers can be managed by the client or by the company that provides them and are usually located in a data center.
The main disadvantage of a dedicated server is the cost of the service, which is much higher than shared hosting. This is mainly due to the monthly cost of the machine and the need to contract the services for the administration and configuration of the server.
The placement service is basically selling or renting a physical space of a data center for the client to place their own computer there. The company gives you the current and the Internet connection, but the server is completely chosen by the user (up to the hardware).
Web hosting in the “cloud” (cloud hosting) is dependent on the state-of-the-art technological innovation that allows a large number of devices to act as a system connected to a group of storage media, has considerable advantages over traditional web hosting solutions such as the use of resources. The security of a website hosted in the “cloud” (cloud) is assured by many servers instead of just one. Cloud computing technology also eliminates any physical limitations to growth in real time and makes the solution extremely flexible.
