Features and specs

What each product offers, as listed by its team.

CloudLinux 5 features
Smartly Calculators 5 features
  • Enhanced Server Stability
    CloudLinux uses its lightweight virtualization technology (LVE) to isolate each tenant on a shared hosting server, preventing any single user from consuming excessive resources and crashing the server for everyone else. This ensures consistent uptime and performance.
  • Improved Security with HardenedPHP and KernelCare
    CloudLinux offers HardenedPHP, which patches old and unsupported PHP versions against known vulnerabilities, and KernelCare, which provides live kernel patching without requiring server reboots. These features significantly enhance server security posture.
  • Resource Limit Management
    Administrators can set granular resource limits (CPU, memory, I/O, number of processes, etc.) per user account using LVE Manager. This makes it easy to manage shared hosting environments and ensure fair resource distribution among tenants.
  • CageFS File System Virtualization
    CageFS creates a virtualized file system for each user, preventing them from seeing other users on the server, viewing sensitive configuration files, or exploiting server vulnerabilities. This adds an important layer of isolation and security.
  • Wide Compatibility with Hosting Panels
    CloudLinux integrates seamlessly with popular hosting control panels such as cPanel, Plesk, and DirectAdmin, making it straightforward for hosting providers to adopt without overhauling their existing infrastructure or workflows.

Possible disadvantages

  • Additional Licensing Cost
    CloudLinux requires a paid monthly or annual license on top of the base server cost. For smaller hosting providers or individual server owners, this additional expense can add up and may not always be justifiable compared to free alternatives.
  • Limited to CentOS/RHEL-Based Systems
    CloudLinux is built on top of RHEL/CentOS and does not support other Linux distributions like Ubuntu or Debian. This limits its adoption for hosting providers who prefer or already run non-RHEL-based environments.
  • Learning Curve for Configuration
    While CloudLinux provides powerful resource management tools, properly configuring LVE limits, CageFS, PHP Selector, and other features requires a solid understanding of the platform. Misconfiguration can lead to users being unnecessarily restricted or resources being poorly allocated.
  • Potential Performance Overhead
    The additional layers of virtualization, resource monitoring, and file system isolation introduced by CloudLinux can impose a slight performance overhead on the server compared to running a bare, unmodified Linux distribution without these controls.
  • Dependency on CloudLinux Ecosystem
    Adopting CloudLinux means relying on their ecosystem for kernel updates, PHP patches, and security fixes. If the company experiences delays in releasing patches or changes its pricing/licensing model, hosting providers may find themselves locked into a dependency that is difficult to migrate away from.
  • Free to Use
    Smartly Calculators offers its suite of calculation tools without any cost to users, making it accessible for anyone needing quick calculations without a subscription or payment.
  • Wide Range of Calculators
    The site provides a variety of calculators covering different categories such as finance, health, math, and other everyday needs, allowing users to find multiple tools in one place.
  • Simple Interface
    The website is designed with a straightforward, user-friendly interface that makes it easy for users of all technical skill levels to input data and get results quickly.
  • No Registration Required
    Users can access and use the calculators without needing to create an account or provide personal information, which streamlines the experience and protects privacy.
  • Accessible Online
    Being a web-based tool, it can be accessed from any device with an internet connection, including desktops, tablets, and smartphones, without needing to download software.

Why this product is good

  • Provides PHP Selector and multiple PHP version support, useful for hosting providers serving diverse client needs

Recommended for

  • Web hosting companies running shared or reseller hosting environments
  • Hosting providers needing to isolate customer accounts on the same physical server
  • Businesses requiring extended OS support lifecycles beyond standard RHEL/CentOS EOL dates
  • Enterprises using cPanel or Plesk that want tighter security and resource control
  • Hosting companies looking to reduce support tickets caused by noisy-neighbor resource contention
  • IT teams managing multi-tenant infrastructure who need governance and monitoring tools built into the OS layer
