At Layershift, we enable our customers to enhance their VPS with leading technologies like CloudLinux, providing platform stability, Security, and DevOps tools designed specifically for web hosting

What Is CloudLinux OS in more detail?


Designed from the ground up to be the best web hosting Operating System available.

  • Lightweight Virtual Environments (LVEs): Isolate user accounts to prevent resource hogging and ensure a stable server environment.
  • Hardened kernel: Enhanced security against rootkits, malware, and exploits.
  • Improved PHP handler (mod_lsapi): Boosts PHP website performance and stability.
  • CageFS: Securely isolates user files and directories, preventing unauthorised access and ensuring data integrity.
  • MySQL governor: Throttle excessive database usage to maintain optimal server performance.
  • Proactive resource management: Set resource limits for CPU, memory, I/O, and more for each account, preventing slowdowns and crashes.
  • Enhanced website monitoring tools: Identify and troubleshoot slow-performing websites quickly and easily.

CloudLinux: Under the Hood - How it Works

Lightweight Virtualization (LVEs):

  • Imagine your VPS as a building with apartments (LVEs) for each website.
  • Each apartment receives a set budget of resources (RAM, CPU, I/O), ensuring no single website monopolises the server.
  • This prevents resource-hungry websites from impacting performance for others, guaranteeing a smooth experience for all.

CageFS - secure isolaton:

  • Think of each apartment's walls as CageFS. It isolates files and directories, preventing websites from accessing or interfering with each other.
  • This keeps your server environment secure by minimising vulnerabilities and potential data breaches.

Combined benefits:

  • Stability: Resource allocation and isolation prevent issues from cascading across websites, ensuring consistent performance for all.
  • Security: CageFS creates individual "sandboxes," minimising attack vectors and protecting your entire server ecosystem.
  • Scalability: Easily add new websites by assigning them their own LVE and resources, allowing your VPS to grow with your needs.
  • Peace of Mind: Focus on your websites, knowing CloudLinux is behind the scenes, keeping your server environment optimised and secure.
  • CloudLinux goes beyond just technical features. It's about creating a reliable, stable, and worry-free web hosting experience for you and your websites.
