What is CloudLinux?
CloudLinux is the first commercial OS that meets the specific needs and demands of web hosting. Imagine if servers going down due to one customer suddenly hogging all the resources was no longer possible. CloudLinux makes rock hard hosting stability a reality. We used to accept that servers will go down during heavy resource spikes and you deal with it by being responsive. CloudLinux does it better by isolating and controlling resource spikes to prevent entire servers going down.
All GreenGeeks shared and reseller hosting accounts come with CloudLinux pre-installed with no configuration required by the customer.
Things you need to know
- Resource Statistics – Every cPanel account will report your hosting accounts resource usage on the left hand side 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.
- Tenant 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 customers. All other customers 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.
