Over the past few weeks, we’ve been rolling out CloudLinux on our web hosting servers. CloudLinux is a new Operating System designed to improve server performance and reliability, while limiting resources each account can use.
CloudLinux is an operating system that uses lightweight virtualization to improve the performance and stability of the server. Using some of the latest technology usually found in cloud environments, it brings some massive benefits to a regular hosting environment. In a shared environment, it was previously possible that one user could install a bad script or run some bad software (often unintentionally), make a coding/programming error or be responsible for some other mishap that could potentially severely slow down or even crash the server. This causes pain and downtime for all of the users on the server.
CloudLinux ensures that each account on the server is given a finite amount of resources that they cannot exceed.
Very few people exceed the generous resource limits we’ve set.
Two things happen if you exceed these resources. The first is you may notice a slow down on your website / hosting account as CloudLinux applies a “soft brake” to your account to prevent it from overloading, slowing down or crashing the server. Once resource utilization reduces, your account will return to normal.
If you massively exceed our resource limits, you will receive a 503 error when trying to access some parts of your website or hosting account. This is CloudLinux taking more severe action to prevent an imminent server crash or overload. If you continually receive 503 errors then you need to evaluate your website / hosting account and see where it can be optimized. A common source of resource abuse is the addon modules often found for the popular open source scripts (WordPress, Joomla, phpBB, Drupal, etc). Try remove some of the unncessary modules and see if things improve. If you are unable to determine the source of the resource abuse, submit a ticket via our helpdesk and we’ll be happy to assist.
Our servers are Intel Xeon E3-1240v2 Quad Core, with 16GB of RAM, We don’t skimp on lower quality hardware.
Accounts per server ranges from 150-350 (many of our competitors will cram 2000+ accounts).
The CloudLinux cPanel plugin adds resource information to your cPanel. This helps you to see how much load your account is generating. You can view this information in the left sidebar of your cPanel account.
