Today we discuss what is Cloud Linux? Have you heard the term “CloudLinux” on a support ticket or in your own research on various Webhosting-related products and wondered what it actually is? CloudLinux is a service that can replace your operating system. Basically, CloudLinux became your new operating system. CloudLinux’s design to make the shared web-hosting environment more secure. This is done by various modifications to the kernel. CloudLinux provides a wide suite of tools through a management interface that allows system administrators more granular control over the resources used by web hosting accounts. Providing this isolation helps prevent an account from causing problems for the rest of your users.
Other advantages are events like high traffic where CloudLinux will throttle the account based on resource constraints. This slows down the specific website where the whole server without CloudLinux can feel the slow performance.
What are the benefits of CloudLinux?
One of the primary benefits of CloudLinux is that it brings a shared hosting environment. Stability, security, and other enhanced security allow Cloud Linux to become a solid product that helps reduce any unnecessary headaches resulting from many hosted accounts.
With CloudLinux you can use packages to set these limits to limit the resources of each account.
CloudLinux Features:
- The Isolation of users prevents disruption from neighboring accounts
- Limit configuration usage, such as CPU, RAM, Inodes, and I / O.
- You can use MySQL Governor to restrict MySQL abusers
- Provides CageFS for isolation.
- Can prevent symbolic attacks
- Works with cPanel and DirectAdmin
- Provides robust PHP version and configuration
- Python and Ruby provide selectors
- Provides PRO mod_lsapi for Apache
- Tough kernel
How does isolation work?
CloudLinux provides capabilities for isolated environments in two ways. The first is through the LVE design which allows the limitation of resources based on the package in a per-account fashion. This helps each website control how it works in terms of its servers. Website A may have higher server resource allocation than Website B but in case of any event of Website B, it will not affect Website A.
Traditional Setup
In traditional hosting, what happens and affects a website can negatively affect everyone else. In this given graph, we use ‘load spike’ as an example. If a large load spike occurs on a website, all other websites on the server are affected due to the lack of a unique environment per account.
CloudLinux Setup
In CloudLinux, each website has its own environment. In this environment, if a website experiences the same ‘load spike’, only that particular website is affected by LVE (Lightweight Virtual Environment) and all other websites run normally.
While using a ‘load spike’ may be an example, the benefits of an isolated account help in other situations as well. Such as denial of service attacks, high traffic events, memory problems, or un-optimized websites. The LVE setup will protect the accounts in this situation
The second method is called CageFS. They describe it as “a one-user file system that encapsulates each client uniquely, preventing users from viewing each other and viewing sensitive information.” CageFS allows each account to have its own cage environment from another account.
With different amounts of malware and website-based exploitation these days and ages, you want that protection.
Conclusion
As the product continues to grow, it can only stand to improve its offer by providing a secure and stable hosting environment. CloudLinux simply makes it easy to maintain your shared server environment. Priced competitively, it gives you some peace of mind knowing that a single user won’t disturb you all day long.
