One of the key features of Cloud Linux is its ability to isolate individual hosting accounts, which helps to improve security and stability. This is achieved through the use of lightweight virtualization technology, which creates separate virtual environments for each hosting account. This means that if one account experiences a problem or is compromised, it will not affect the other accounts on the same server. Another feature of Cloud Linux is its ability to provide advanced resource management, which allows hosting providers to set limits on CPU usage, memory usage, and other resources for each hosting account. This helps to prevent any one account from monopolizing server resources and slowing down the performance of other accounts.
