Web hosting services with CloudLinux

CloudLinux is an operating system optimized for web hosting. It distributes server resources and efficiently delimits users. With CloudLinux, web hosting becomes even more stable and secure.

Why CloudLinux

Standard web hosting has just one server that contains all users and all websites in different folders. They all use one web server and one database server. If one website starts consuming too many resources, other websites will slow down, or the whole server will become unavailable. Furthermore, it’s simply not secure: by getting access to just one website, hackers will be able to hack other websites too.

Web hosting is more stable and secure with CloudLinux. This operating system isolates users and delimits available user resources. Therefore, one website will not be able to slow down the others, and viruses and bots won’t get access to the whole server.

With CloudLinux, hosting providers don’t have to be afraid that one of the clients will have problems with resources, so they can have more websites on one server node. By using different limits on various tariff plans, you as a provider can offer more enterprise services to your clients. CloudLinux helps you generate more profit!

CloudLinux benefits

Limitation of system resources

A hosting administrator can select what resources to give to every user: CPU, RAM, input/output operations and simultaneous connections. If one website overcomes this limit, it won’t affect other websites.

User caging

CageFS virtual file system incapsulates every user and limits its access to other users and a server itself. It prevents from most hacker attacks and data stealing. You don’t have to change clients’ installation scripts to use this system.

PHP Selector

Websites using standard web hosting have to keep the same PHP version. It means that all of them are of about the same age but it doesn’t really happen often. With CloudLinux, every user may have its own PHP version and not care about a difference between project versions.

Limitation of database usage

Resources of your web server and MySQL server are quite limited. If a website meets high traffic load or CMS caching settings are changed, it might overload the mutual database. As a result, all websites on the server will fail to respond. MySQL Governor will control how MySQL is used and limit potential load on the database server for every user.

Faster websites

If a website is slow, your client won’t like it, as well as SEO systems. CloudLinux supports the LSAPI mode which guarantees high PHP processing speed and faster loading of dynamic websites. LSAPI extends the possibilities of CageFS and PHP Selector.
