Features and specs

What each product offers, as listed by its team.

Airalo 5 features
CloudLinux 5 features
  • Global Coverage
    Airalo offers eSIMs that work in over 190 countries, providing extensive coverage for travelers worldwide.
  • Cost-Effective
    Their eSIM plans are often cheaper compared to traditional roaming charges, making it a budget-friendly option for international data usage.
  • Instant Activation
    Users can instantly activate their eSIMs without having to wait for physical SIM cards to be delivered, ensuring immediate connectivity.
  • Environmentally Friendly
    By using eSIM technology, Airalo reduces the need for plastic SIM cards, making it an eco-friendly option.
  • User-Friendly Interface
    The Airalo app and website are designed to be user-friendly, making it easy to purchase, activate, and manage eSIMs.

Possible disadvantages

  • Device Compatibility
    Not all devices support eSIM technology; users need to ensure their smartphone or device is compatible with eSIMs.
  • Data-Only Plans
    Most of Airalo's eSIMs are data-only, which means users cannot make traditional voice calls or send SMS through the eSIM.
  • Customer Support
    Some users have reported slow or unresponsive customer support, which can be frustrating if issues arise.
  • Limited Local Providers
    In some regions, the available networks may be limited to fewer local providers, which could affect coverage and data speeds.
  • No Shared Data
    Unlike traditional SIM cards, eSIMs typically cannot share data across multiple devices, which may be a disadvantage for users with multiple devices.
  • 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.

Overall verdict

  • CloudLinux is a well-regarded, mature Linux OS distribution and toolset specifically designed for shared hosting and multi-tenant server environments, offering strong isolation, resource management, and security features that make it a solid choice for hosting providers.

Why this product is good

  • Provides LVE (Lightweight Virtual Environment) technology for per-tenant resource isolation, preventing 'bad neighbor' effects on shared servers
  • Enhances server stability and security by isolating users so that one account's issues (crashes, resource spikes) don't affect others
  • Offers extended lifecycle support (longer than standard CentOS/RHEL support windows), which is valuable for legacy systems
  • Includes tools like CloudLinux OS Shield, Imunify360 integration, and hardened kernel options for improved security
  • Compatible with popular control panels like cPanel and Plesk, making it easy to integrate into existing hosting stacks
  • Backed by an established company with a long track record in the hosting industry and responsive support
  • Offers granular control over CPU, memory, I/O, and other resources per user account
  • 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

  • Canadian Phone Plans for International Travel
    If your phone supports e-SIM I would recommend something like Airalo. Source: over 3 years ago
  • Traveling abroad from the states, need some help.
    Alternatively look for a data esim like esimdb.com or airalo.com for regional esim you can install prior to departure. Can check the big Euro carriers for regional deals like Orange or 3, etc. Source: over 3 years ago
  • Cell Service/WiFi or other options?
    I was just the Marangu route. There was wifi in the huts, but I bought e-sim for data. It was available almost everywhere. I used airalo.com. But find even more similar companies. Source: over 3 years ago
