=== <big>CloudLinux OS – Overview</big> ===
<big>'''CloudLinux OS''' is a '''commercial Linux distribution''' (paid, subscription-based) designed specifically for '''web hosting providers, data centers, and enterprises''' that run shared hosting environments.</big>

<big>It is based on '''RHEL (Red Hat Enterprise Linux)''' / '''CentOS''' but adds powerful features for '''security, stability, and performance isolation''' in multi-tenant servers.</big>

=== <big>Why CloudLinux?</big> ===
<big>In shared hosting, multiple websites are hosted on the same server.</big>

* <big>If '''one website uses too many resources (CPU, RAM, I/O)''' → the entire server can slow down or crash.</big>
* <big>If '''one site gets hacked''' → other sites are at risk.</big>
* <big>CloudLinux solves this by '''isolating each tenant (user/account)''' into a lightweight, virtualized environment with its own resource limits.</big>

=== <big>Key Features of CloudLinux</big> ===

# '''<big>LVE (Lightweight Virtualized Environment)</big>'''
#* <big>Isolates each user (like a mini VM inside the server).</big>
#* <big>Sets resource limits: CPU, RAM, Disk I/O, Inodes, Entry Processes.</big>
#* <big>Prevents one user from overloading the entire server.</big>
# '''<big>CageFS (Secure Virtualized File System)</big>'''
#* <big>Each user sees only their own files and processes.</big>
#* <big>Blocks users from viewing sensitive system files.</big>
#* <big>Increases security in shared hosting.</big>
# '''<big>Imunify360 (Optional Add-On)</big>'''
#* <big>Advanced malware protection, firewall, intrusion detection.</big>
#* <big>Automated malware scanning and cleanup.</big>
# '''<big>PHP Selector & Ruby/Python Selector</big>'''
#* <big>Users can choose their own PHP version (5.x → 8.x).</big>
#* <big>Supports multiple versions of Python and Ruby.</big>
# '''<big>KernelCare (Optional Add-On)</big>'''
#* <big>Live kernel patching without rebooting.</big>
#* <big>Keeps servers secure with zero downtime.</big>
# '''<big>MySQL Governor</big>'''
#* <big>Monitors and limits abusive MySQL queries.</big>
#* <big>Prevents one account from hogging database resources.</big>
# '''<big>Resource Usage Monitoring</big>'''
#* <big>Hosting providers can track usage and prevent abuse.</big>
#* <big>Customers can see their own resource usage in cPanel/DirectAdmin.</big>
