Features and specs

What each product offers, as listed by its team.

Hazelcast 5 features
CloudLinux 5 features
  • Scalability
    Hazelcast is designed to scale out horizontally with ease by adding more nodes to the cluster, providing better performance and reliability in distributed environments.
  • In-Memory Data Grid
    Hazelcast stores data in-memory, allowing for extremely fast data access and processing times, which is ideal for applications requiring low latency.
  • High Availability
    Hazelcast offers built-in high availability with its data replication and partitioning features, ensuring data is not lost and the system remains operational during node failures.
  • Ease of Use
    Hazelcast provides a simple and intuitive API, making it accessible to developers and quick to integrate with existing applications.
  • Comprehensive Toolset
    Hazelcast offers a wide range of features including caching, messaging, and distributed computing, all in one platform, which simplifies the architecture by reducing the need for multiple tools.

Possible disadvantages

  • Memory Usage
    Since Hazelcast operates in-memory, it can consume significant amounts of memory, which may be a concern for applications with large datasets.
  • Complexity in Large Deployments
    While Hazelcast offers scalability, managing and configuring a large-scale deployment can become complex and may require experienced personnel.
  • License Cost
    The enterprise version of Hazelcast, which offers additional features and support, comes with a licensing cost that might not fit all budgets.
  • Limited Language Support
    Hazelcast's strongest support is for Java. While it offers clients for other languages, they may not be as robust or feature-complete as the Java client.
  • Network Latency
    In distributed environments, network latency can impact performance, and as Hazelcast relies on network communication for node interactions, this could be a concern in some scenarios.
  • 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
