System Resource Limits

CloudLinux is a specialized Linux distribution that allows us to limit the resource usage of individual cPanel accounts. This ensures that no single account can exhaust the server’s resources, providing a stable hosting environment for all users. Below are the limits we set for our web and cloud hosting:

Resource	Limit
RAM	Up to 16GB DDR5 (depending on package)
vCPU	Up to 6 vCPU (depending on package)
Entry Processes	Up to 600 (depending on package)
NPROC	Up to 1200 (depending on package)
IO	No cap
IOPS	No cap
Inodes	Unlimited

Explanation of Terms

• RAM (Random Access Memory): A type of computer memory that temporarily stores data and machine code currently being used. Higher RAM allows for better performance, especially with multiple concurrent users.

• vCPU (Virtual CPU): A virtualized CPU core that allocates processing power to virtual machines. The number of vCPUs can significantly affect the performance of your applications.

• Entry Processes: The number of simultaneous processes that can be initiated by a user. This includes web requests, SSH sessions, and cron jobs. Limiting entry processes helps prevent server overload.

• NPROC (Number of Processes): Refers to the total number of processes a user can run simultaneously. Setting a cap ensures that no single account monopolizes server resources.

• IO (Input/Output): This measures the data transfer speed to and from the storage system. Higher IO limits allow for faster data processing and retrieval.

• IOPS (Input/Output Operations Per Second): Indicates the number of read/write operations a storage device can perform in a second. Having no cap means that users can perform as many operations as needed without restriction.

• Inodes: Structures that store information about files and directories in a file system. Having unlimited inodes allows users to create as many files and directories as they require without concern for limitations.
