8/14/2015 – Understanding CloudLinux

Posted by Jamison on 14 08 2015.

What is CloudLinux?

 

The CloudLinux operating system optimizes server performance by its ability to set an amount of CPU or memory to its account.  This is can be useful by ensuring managed memory resources so other clients will not be disadvantaged by a resource spike from other client.  With this, there will be fewer service interruptions on admin due to tracking of user and suspension of user’s activities.

 

Fewer support inquiries = increase server uptime = reliable hosting environment = happy clients

 

Another important benefit is it provides a more stable and secure environment for your shared clients by its tenant isolation feature.  It protects the whole server from going down if one account fails.  As CloudLinux states under their security benefits, with the operating system:

 

	Users do not see other users on the server
	Users are caged and have access only to safe files
	Users can see only their own processes
	Large number of attacks will…

  • Users are caged and have access only to safe files
  • Users can see only their own processes
  • Large number of attacks will be prevented against server

 

If you are currently running on CentOS or RHEL, it is easy to convert to CloudLinux through the yum (CentOS package manager).

 

CloudLinux Core Programming

 

The driving technology behind CloudLinux is the Lightweight Virtual Environment (LVE).

LVE is a lightweight and transparent kernel technology which increases your server’s density, stability, and reliability.  It manages the resource monitoring of your CPU, disc I/O, and memory across all your clients.

 

Through the new plugin specifically designed for cPanel and WHM, server administrators can now easily view resources accurately and manage configuration of the CloudLinux settings per client.  System administrators called LVE Wrappers are designed to patrol this.  As such, LVE is aimed to bring the following results:

 

  • Lowered risk and increased efficiency on the server by:
  • Identifying accounts that are using capacity beyond its supposed resource level
  • Protecting other accounts from other users. These will increase the security of the account from having its data stolen from a shared server.
  • Preventing a single account from taking down a server
  • Increased density because of managed CPU usage; hence, you can host more tenants
  • All these are designed to improve the performance of your server.

 

  • There are also other tools available that make system administrators life easier:
  • MySQL and I/O governors – designed to assist MySQL connections issues, as well as RAM and I/O control concerns.
  • PHP Selector – allows administrators to select the PHP version of the server. The tool can also enable and disable specific PHP modules.
  • CageFS – packs a selection of tools to prevent hackers from viewing configuration files or scanning vulnerable files.

 

The abovementioned are CloudLinux tools that help reduce system support queries, hence saving you time and money at the same time making customers happy.
