Until now, each account on our web servers got an equal share of available resources. Whilst this wasn’t a problem for us as we run well maintained, non-oversold servers, we have now added an extra layer of stability that will mean rock-solid hosting.
CloudLinux keeps our servers up and our clients happy even under extreme stress. That's because each tenant is isolated in their own lightweight virtualized environments (LVE) and given a predetermined amount of resources. If one customer suddenly get's a huge amount of traffic any ill effects will be contained to only that client. Traditional shared hosting environments have no control over individual tenants in the event of a resource spike. If one tenant suddenly experiences a big resource spike from a large amount of traffic, poorly written script, or a denial of service attack, all the other tenants on the server are slowed or brought down.
CloudLinux isolates each tenant so that no matter what, the tenant can never exceed the resources allocated to them. During a sudden resource spike all other tenants are left unaffected.
