Features and specs

What each product offers, as listed by its team.

ReadyTech 4 features
CloudLinux 5 features
  • Comprehensive Solutions
    ReadyTech offers a wide range of solutions covering various sectors such as education, workforce management, and government, making it a versatile choice for organizations in need of integrated technology solutions.
  • User-Friendly Interface
    The platforms provided by ReadyTech are designed to be intuitive and easy to use, which helps organizations to quickly adapt and fully utilize the software capabilities with minimal training.
  • Cloud-Based Platform
    Being cloud-based, ReadyTech ensures that users can access their services from anywhere, promotes collaboration, and reduces the need for complex on-premises infrastructure.
  • Scalable Solutions
    ReadyTech’s offerings are customizable and scalable, which allows organizations to tailor the platform according to their specific needs and grow along with their demands.
  • 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

Questions & Answers

What's the story behind your product?

ReadyTech's answer

Built for Instructors by Instructors It was 2002 when we started thinking about what, if anything, could be done remotely. At first, we concentrated on the most problematic part, which was the virtual lab environment. In these early days, virtualization wasn’t ready for prime time, so we focused on building a hardware-based lab solution. It was during that time that our mantra, “worldwide performance and stability,” was established. We knew if we could achieve that, our solution would work.

In 2003, we launched, and it was an immediate success with customers. As virtualization technologies matured and cloud services started to develop (AWS launched in 2006), we added cloud hosting to our solution. More importantly, we began to think beyond the lab and are now building various tools to help instructors deliver excellent training and keep students engaged. We are no longer in that small loft. We are headquartered in Uptown Oakland, with international offices in the Netherlands and data centers in California, Singapore, and Amsterdam. While we have been tempted into other markets, we have decided to stay firmly focused on where our passion is: the training business.
