Features and specs

What each product offers, as listed by its team.

Sideline 5 features
CloudLinux 5 features
  • Cost-Effective
    Sideline offers a secondary phone number for a fraction of the cost of a second traditional phone line, making it an economical choice for small businesses and freelancers.
  • Flexibility
    Allows you to have a separate business line on your personal smartphone, helping to keep work and personal calls distinct without needing another device.
  • Carrier Integration
    Calls are made using your carrier's network, which can provide better call quality and reliability compared to VoIP services.
  • Features
    Offers valuable features like auto-reply, voicemail, number porting, and team number sharing, which enhance its functionality for business use.
  • User-Friendly Interface
    The app has an intuitive and easy-to-use interface, making it accessible even for users who aren't tech-savvy.

Possible disadvantages

  • Carrier Dependency
    Relies on your primary carrier's network, which may be a limitation if you have poor reception in your area or if you're on a constricted mobile data plan.
  • Limited Advanced Features
    Does not offer as many advanced features as some VoIP-based services, like call recording or extensive analytics.
  • Subscription Cost
    While more cost-effective than a full second line, it is still a monthly subscription cost, which can add up over time.
  • International Limitations
    Primarily geared towards U.S. and Canada use, which may limit its effectiveness for international business needs.
  • SMS and MMS Limitations
    Some users have reported issues with sending and receiving SMS and MMS, particularly with media files.
  • 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.
