Hosting Web Services On Virtual Environment

Web hosting companies provide shared hosting services with a lot of features, but sometimes they set heavy limitations for secure environments.

For example:

• You generally use PHP / MySQL or ASP.NET / MS SQL.

• There is no access to the web server logs or logs to MySQL or MS SQL.

• You have to use phpMyAdmin, though there are certain limitations over MySQL / MS SQL access.

• You cannot install web applications of your choice.

• Services on ports are disabled other than port 80.

You can enjoy total freedom by hosting a website on your home-based machine, but there are certain limitations.

• You have to leave your computer on 24x7x365 days.

• The download or upload speed will be slow, so your website will be slow to access.

• A vulnerable environment for the website, means your machine can be easily hacked.

• You have to troubleshoot errors yourself.

Hence, you need to consider a new generation of trustworthy hosting type that is increasingly popular: The hosting of virtual private servers.

Principle:

• It gives you access to a virtual machine located on a large server and a high-internet connection (the virtual machine behaves like a dedicated server ).

• Your virtual machine ( VPS server ) will have a certain amount of dedicated RAM, disk space, and dedicated IP addresses.

• You can choose any operating system according to your requirements.

• You will get root access to your virtual server and much more.

From there, you can do anything you want on your virtual private server.

For example:

• You can shut down / reboot your virtual machine.

• Ability to install a web server (Apache, Tomcat, Lighthttpd, or else!), PHP, ASP.NET, MySQL, MS SQL, Python, Ruby, CGI, etc.

• You can install your programs.

• Able to set as many services as you want (HTTP, ssh, FTP, SMTP/pop3, etc. …).

• Reinstall in a few minutes the entire operating system (on request).

• You can upgrade your virtual server resources such as RAM, and disk space (on request).

This is a new way of the hosting service which gives you total freedom on the server.

Benefits:

• Total freedom on the server.

• You can install what you want, as long as you have a license (python / CGI programs compiled by you, etc..).

• You can run all the services you want.

• You can stop/restart the machine whenever you want.

• You will have SSH access to your machine to control the environment.

• You will have access to a console that allows you to take control of your machine.

Note:

It takes skills in system administration, for example: if you are not familiar with the installation of Apache / Tomcat, MySQL / MS SQL, PHP / ASP.NET configuration, and server security then it is recommended to opt for fully managed services from the web host.
