CloudLinux is a basically a platform which virtualizes user accounts (called LVE). Each LVE is allotted a certain amount of resources.
If a particular account receives a sudden large amount of traffic or begins to use a lot of CPU or memory, rather than slowing the entire server and possibly causing a failure, it will slow only that particular LVE.
So you do not need to worry about other clients hogging server resources or causing unnecessary downtime.
All HostMantis shared and reseller hosting accounts come with CloudLinux pre-installed with no configuration necessary.
Things you should know
- Resource Usage Statistics - Every cPanel account will report your hosting accounts resource usage on the left hand menu under the Quick Stats section. You may also click on the "Resource Usage" icon under the Logs section. You can use these tools to help you monitor your sites resource usage to determine whether you need to optimize your site or upgrade.
- Account Isolation - If in the event that your site receives a large number of visitors or is using too many resources, our system will automatically adjust to try and accommodate the demand. If however you're exceeding your limits, your site will be slowed down temporarily to prevent any outages for other clients. All other client sites will continue to work at full speed.
- 500 Internal Server Error - If you see an 500 error appear randomly, this is because our system is limiting you for exceeding your memory limit. You will have the ability to optimize your site to prevent this error from occurring by using caching plugins, optimizing code, etc. Note: This error code is also common when incorrect permissions or file types are uploaded to the server. If you're not sure, you can always contact support and we'll be able to help you determine the issue. However, you can check yourself by looking at the "Resource Usage" in cPanel to see if you're hitting your limit.
- 508 Error - You will see this error when your account has exceeded the maximum number of concurrent connections or "Entry Processes" allowed to your account. This will self manage it self as your connections fluctuate.
