There are two different implementations :
- shared hosting
- virtual private servers
Shared hosting
This is the most common kind of hosting. You configure a separate directory for each domain. Each domain shares resources with others, including the web server, mail server, and all other key components of the system. Users have a limited autonomy to run theirs applications.
This type of hosting has a number of disadvantages:
- Stability Issues - As users of different domains are sharing the operating system, web server, mail server, and other key resources of the system, a technical problem, a user may lead to a shutdown, which also involves domain other users cohabiting.
- Poor performance - there is no way to effectively control the use of resources in a shared hosting environment. A user can consume a large portion of CPU, memory or disk space, causing a shortage of available resources for other users.
- Safety issues - data and configuration parameters are mixed in the shared environment and are protected only by password. The security of your data can be easily compromised.
- Problems of customization and control - Since each user shares the same environmental system components, many configuration parameters must be configured in an absolutely similar manner to each others. This greatly restricts the ability to control and set them individually.
Virtual Private Server (VPS)
This innovative technology was introduces to create virtual partition that run in a manner equivalent to that of a dedicated phisycal resource. The term used to define this concept is "hardware virtualization".
The sophisticated technology behind the scene that supports hardware virtualization solution appears to be a more evolved level in respect to shared hosting, it is easy to use and at the same time implies the elimination of the disadvantages of shared hosting.
Some of the key advantages are:
- Isolation - The Virtual Private Server is fully isolated. A crash of the operating system of a Virtual Private Server has no impact on other simultaneously running on the same physical server.
- Performance - The Virtual Private Server receives a specific allocation of CPU, memory and disk. The environment allows for reasonable levels of peak, but it exclude a single VPS to take possession of the all available resources. This means that each VPS receives a guaranteed level of service.
- Security - Virtual Private Server is in all respects exactly like a dedicated server, allowing the full use of a pattern of desired security without any mixture of data with other VPS.
- Control - The Virtual Private Server can be managed with a total control of all configuration parameters using a simple web management interface. The configuration parameters of the operating system is completely independent from the other VPS, and you can install and use applications that could not coexist with other domains in a traditional shared hosting environment.
In the following table the management and controls of your virtual server:
| Features | Benefits |
|---|---|
| Control panel | The interface of the control panel allows you to manage all the configuration parameters and operating the system via web interface. |
| Resources use visibility | The control panel provides current and historical information about using resources (eg disk space), allowing you to monitor the health of your server and determine if additional resources are required. |
| Backup management | Backing up the Virtual Private Servers and all your data is performed automatically each night. From the web control panel you can manage backups, and recover instantly in case of need the status of your system and your applications. |
| Support | The Virtual Private Server is easy and immediate use. If you have any questions or problems, you can use the Help Desk service of the site. If you want a direct and dedicated technical support to your company, you can buy a package of our consulting services. |
| High performances | Your application receives the resources guaranteed. Virtual Private Servers store the data of the operating system and applications on fast disks configured in RAID for added protection of your data. |
