Today, all leading hosting providers are offering CloudLinux for their shared hosting services. CloudLinux OS was first introduced in 2010. This is a leading platform that offers multi-tenancy that improves the overall density, security, and stability by separating all tenants. Using the CloudLinux, you can reduce your cost and raise profitability. CloudLinux is majorly designed for shared hosting providers. In this article, I will discuss some major features and benefits of CloudLinux for shared hosting. Many shared hosting service providers are collaborating with CloudLinux to offer multitenancy to their users.

There are enormous benefits associated with CloudLinux OS that would help you to improve your shared hosting experience.

Read this article to have a better understanding of CloudLinux OS, the key benefits of CloudLinux OS, and why you should use CloudLinux OS for shared hosting.

What is the CloudLinux OS?

CloudLinux OS is mainly designed for shared hosting services. It is an improved kernel, based on an OpenVZ kernel that you can interchange with the existing CentOS kernel in a few steps. CloudLinux isolates all tenants on shared server resources into a separate lightweight virtualized environment (LVE) to limit or improve each tenant’s server resources; thus, improving the stability, security, and density of all tenants. It improves the overall data stability, security, and density by isolating every tenant using shared server resources into distinct LVE, to increase or limit all server resources of all tenants. The following are the purpose of tenants’ separation in the CloudLinux shared hosting:

• • It isolates its tenants from one another to eliminate the security breaks.

• • It supports protecting the server from slowing down because of the activities of other users in the same network.

• It restricts the spread of viruses and malware on any website of the client.

CloudLinux is the only OS designed specifically for shared hosting services, it offers a lot of additional benefits such as stability, security, and easy management. Not all OS offers the same benefit as CloudLinux. LVE” Technology is something that makes CloudLinux stand out.

LVE technology makes CloudLinux different from the rest of OSs, CL made this Kernel module to ensure that not one single website can bring down other web servers, it does this by controlling/limiting (respectively) the amount of RAM and CPU available to a process.

Key Benefits of CloudLinux OS

Following are the major benefits of using CloudLinux OS for shared hosting. 

Advanced Security:

CloudLinux OS keeps releasing advanced security patches to keep clients’ websites protected. The LVE technology of this OS also helps to prevent hackers and malware from getting into confidential files from the site or accessing your data from other users using the same server resources. you can also say that CloudLinux supports creating bubbles that protect your hosting account by not allowing hackers to access your data or preventing your information from leaking out. SecureLinks is a kernel-level technology that stops all symlink attacks. It improves the servers’ level of security and prevents malevolent users from making symlink files.

Customer Isolation:

its LVE protects the accounts of individual from spiteful attacks; it defends your server from being affected when other users’ account goes down, different from other servers that immediately get down when one account is down. In the CloudLinux, an isolated environment is provided to all users to reduce the dependency and this is attained by managing the amount of CPU and RAM that can be used within your server while an operation running. Per-tenant resource limits and allocation for CPU, memory, and IO decrease loads on the server. When corresponding with performance-enhancing features (Mod_lsapi, MySQL Governor), this promises the fastest servers.

Visibility:

CloudLinux offers its users higher visibility of their resources. Though using the “tenant” model, the OS makes it simple for users to screen system logs or log attempts that could be possible security coercions, running all executions by a user reverse.

For example, it is easy to remove spiteful scripts, those wanting to get unauthorized privileges, or spam.

Stable Hosting Environments:

Unexpected traffic spikes from an account of one website will never mean interruption for another server or website account. As all websites’ account has its own assigned resources, they continue to be secure. This also keeps sites active even if an unexpected spike in usage of resources comes from other sites on the same server.

Ease of Conversion:

It is very easy and important to adapt from other OSs to CloudLinux OS. Converting from CentOS or RHEL does not take a lot of time to finish. In addition, you can purchase your license from any platform and enjoy great security patches and updates.

Excellent Support:

For CloudLinux, customer service support is very pleasing. They can simply support you to get through configuration, usage, and installation issues and also resolve bug fixes and run diagnoses to know the issue with your site.

Secure/Harden Kernel:

The secure kernel stops nasty users from attacking the website of another user on the server through symlink protection, and trace activity by limiting the ProcFS visibility to only what is compulsory. We all know that cleaning up a hacked server is terrible. Thus far, hacked and defacement account is a battle for hosting providers regularly. Not only does it take a lot of time, but it also defames your company and makes your customers unsatisfied. The core reason is that it is very easy to hack shared hosting servers because Linux was not meant to be used by a huge number of unexamined users.

If you are using Linux for your hosting, it would be very easy for the hackers to attack your servers by signing up and using a stolen credit card or by mistreating some obsolete script that your customers have not updated. Afterward, a hacker has confidential access to your server and can start poking around and hacking your server.

Database Stability:

CloudLinux also offers MySQL governor. It is a vital tool to restrict and monitor MySQL procedures in a shared hosting setting. This tool gives you an option for running an operation on multiple modes. MySQL frequently turns out to be a major pain for system administrators in shared hosting settings. It can be hard to keep MySQL stable, and customer queries can slow down everything.

Cloudlinux’s MySQL Governor feature supports system admins to identify abusers and control them in real-time. It tracks disk IO and CPU usage for every account of the website in real-time and decreases MySQL queries through the same LVE limits for every user. With support for the MariaDB MySQL latest versions, for all shared hosting providers, it is a must-have. 

Compatibility:

One more major benefit of CloudLinux OS is its compatibility with other interfaces such as cPanel. Thus, the higher compatibility of the two interfaces allows users to have lower frustrations and higher services. With this OS, you will get a faster and free hosting experience gives your customers the ability to control their resources on the website. Now, you can enjoy the higher CloudLinux OS stability without compromising on compatibility. It works with major control panels such as cPanel, Plesk, LITESPEED, ISP Manager, Direct Admin web control panel, and Webmin, and it is compatible with many software usually used with RHEL and CentOS.

Multiple PHP Versions:

CloudLinux has an incorporated feature known as a PHP selector. It lets end users select the exact PHP version they need. This OS also allows more flexibility by offering all widespread PHP versions, plus over 120 PHP extensions to pick from.

 this OS packages PHP versions 4.4, 5.1, 5.2, 5.3, 5.4, 5.5, and 5.6. The suitable UI allows clients to select extensions, switch between versions, and alter PHP settings as required. HardenedPHP secures unsupported and old PHP versions.

WHM Admin Interface

The GUI is designed in a basic format for easily modifying, managing, and monitoring user accounts on RAM, CPU, and I/O practice. Additionally, CloudLinux has presented organizations with reliable, easy, affordable, compatible, and secure customer support to successfully host their site. Therefore, it is highly recommended to use these opportunities to get all of the benefits associated with CloudLinux OS.

Why Hosting Providers Prefer Cloudlinux OS?

A typically shared hosting environment usually includes hundreds of websites being hosted on a single server; all websites share the same resources. The server admin, though, gets a little power over how individual accounts are using the resources of the server.

In case any user in the shared hosting is exploiting the server resources because of a rapid surge in traffic, or perhaps due to a DDoS attack or bad script, the whole server slows down (it can also completely go down) affecting other users hosting their websites on the same server.

The typical shared hosting does not allow limiting the server resources for a specific website account slowing down the server. Furthermore, finding the bad apple causing all of the issues can be a difficult task, getting to the core of the problem might require you to suspend the site causing the problems. Eventually, this may result in unsatisfied users because their business is also affected by the whole process.

CloudLinux shared hosting environment is here to resolve all of the issues faced by hosting providers and users in typical shared hosting.

In a hosting environment of CloudLinux, each website (LVE) has set limits of resources to protect users from bad consequences like bad scripts and abusers. This raises a strong hosting environment in which the unaffected websites run normally without problems such as load speed or downtime.

In the case of CloudLinux shared hosting. if any account is suspected of exploiting the resources, it stops working temporarily until its usage of the resource becomes normal. Users of this site will usually be presented with a 503 error when they attempt to access it. This is done to keep that website account from consuming all server resources, and this is possible just because of the LVE technology used in CloudLinux. It is a win-win situation for both service providers and users.

Why CloudLinux OS is Best for Shared Hosting?

You might know how it works in a shared hosting environment when there are hundreds of websites sharing servers with you, as such, the server admin has limited control over the server’s resources used by websites. You have to keep the resources undamaged therefore not allowing abusing the server resources. It is fairly hard to limit RAM, CPU, and other server resources to all websites.

There are conditions when a website seems to be consuming a maximum server’s resources (unexpected spike in the use of resources) that can be due to poorly written scripts or heavy traffic and more possibly, DDOS attacks. These conditions are known to be the most challenging for the admins of the server to manage daily and can result in downtime for other websites on the same server or it can also result in an unresponsive server.

CloudLinux was launched in 2010, it can be quite beneficial to attain high stability on the shared hosting server environments. CloudLinux offers LVE with CAGEFS that condense a site in an isolated virtual environment. Using this technology, the servers’ resources can then be monitored, limited, and managed through a GUI tool LVE manager. So, it can be said that CloudLinux OS is the best option for shared hosting because it allows you to overcome all the issues in typical shared hosting. It offers more security and stability.
