CloudLinux OS: What Is It, Its Advantages, Key Features & Use Cases

CloudLinux is an operating system specially designed to serve as a server OS for hosting websites. The main purpose of this operating system is to maintain stability, security, and web hosting server speed on multiple websites, as they are hosted on the server. Also, CloudLinux provides fair use of resources-each website gets its share of CPU and memory space so that one website is not able to suck its life away and at the same time slow down.

CloudLinux OS has a noteworthy feature called Lightweight Virtual Environment (LVE). Just as a manager looks after different departments’ employees in the organization, LVE watches how many resources are utilized by different websites so that they do not exceed too much. Also, there is resource sharing among them.

More importantly, even beyond the resource sharing, it is security that is being addressed by this OS. There are also some protections offered against some forms of attacks that may harm the websites, even though it is meant to avail such resources.

From all accounts, CloudLinux OS is one safe, sound, and reliable option for hosting websites, especially in the case of demanding web hosting servers that host multiple websites on a single 

shared platform. Focus on stability, security, and performance makes it a much sought-after OS for web hosting providers as well as website owners.

Known for its premium features mainly meant for enhanced shared hosting environments, CloudLinux offers some very useful use cases as illustrated below: 

• Better Security: CloudLinux boasts of its capability to isolate hosting accounts from one another using LVE (Lightweight Virtual Environment). It adds security against a single user affecting other users on the shared server in case of a compromise on one of these accounts. Each website runs in its own secure environment, thereby reducing any server-wide vulnerabilities.
• Better Performance: With features such as CageFS, CloudLinux creates a virtualized file system that ensures access by users only to files necessary for their accounts, thus improving performance and stability while preventing access to excessive resources such as CPU and RAM, where slowdowns or crashes would result. 
• Reliability and Resource Optimization: CloudLinux enables server administrators to set resource limits for each user, thereby preventing unplanned use of one website from damaging other websites residing on the server.
• PHP Selector: CloudLinux allows multiple versions of PHP on a server. This gives users the ability to run applications that rely on older PHP versions while others enjoy the latest updates for diversifying use in the compatibility of performances for several web applications.
• Isolate User Accounts for Shared Hosting: CloudLinux is the best solution for web hosting companies to ensure the stability and reliability of multiple accounts on a server. Isolation technology indeed makes it perfect for an environment where many other customers’ websites coexist on a single common server but at the same time assure strong security and streamlined management.

AlmaLinux OS: What Is It, Its Advantages, Key Features & Use Cases

AlmaLinux was first introduced in March 2021, which is an open-source Red Hat Enterprise Linux distro, i.e., RHEL. After CentOS decided to stop developing its highly stable operating system, CloudLinux took over by launching AlmaLinux, as a new free and open source alternative operating system.

AlmaLinux assures complete visibility in its governance and is publicly available. The fact that it usually rolls out fresh news, and provides guidelines, source codes, and how-to-install software on AlmaLinux guides ensures that the masses are familiar with how to update anything easily. 

It comes with a migration tool i.e. the AlmaLinux migration tool and also provides users access to the source code. But saying, “Old is Gold” has a certain weight in this scenario because AlmaLinux is just new and hasn’t really picked up on popularity; hence, moving to AlmaLinux OS becomes a hard nut to crack. AlmaLinux comprises different other purposes as a server operating system. It is robust, versatile, and reliable on all web server types, whether hosting server, file server, database server, or email server and is a very secure and reliable platform for businesses of every size.

AlmaLinux is a very versatile operating system when it comes to running many applications, especially in enterprise environments. Important use cases include:

– Web Server Hosting:

AlmaLinux provides a very secure environment where web server functions can quite easily undertake routine operations. It is much used by large-scale enterprises. It also never fails when combined with commercial control panels with a variety of its applications, from simple hosting to more complicated solutions for enterprises​.

– Cloud Hosting:

Because AlmaLinux is engineered for use within a cloud, it delivers complete reliability and performance for virtualized applications. So many cloud hosting providers have recently joined the ranks of offering AlmaLinux as an option, providing all of the scalability and security found on a cloud-hosted infrastructure​.

– Web Hosting & Content Management Systems:

AlmaLinux could be quite convenient to use for web hosting and content management systems (CMS) like WordPress as it is capable of providing stability and high performance while operating websites with a great deal of traffic. This will ensure a smooth flow of operations and faster loading of web pages​.

A Comparative Overview of CloudLinux and AlmaLinux

Both these operating systems CloudLinux and AlmaLinux are robust, each offering something different for every hosting requirement. Resource isolation and stability offered by CloudLinux are meant for shared hosting, and AlmaLinux gives open-source flexibility to continue with the tradition of CentOS. Put together, they form an altogether different use case while trying to make an informed decision on server management.

• Performance: CloudLinux always makes use of the LVE technology, i.e., Lightweight Virtual Environment, which allows for the precise allocation of resources for each user. It’s the perfect solution of choice for hosting platforms that require equitable sharing of resources among different users. Contrary to the older CentOS, AlmaLinux aims at modernizing approaches to performance improvement. It is an ideal operating system for projects where the resource isolation performed at user levels adds unnecessary overhead to project throughput.
