There are currently many operating systems that are developed with a fundamental purpose and it is to allow administration tasks to be much simpler, but at the same time more complete. One of these systems is ClearOS which is an open source operating system which is based on CentOS and Red Hat Enterprise Linux (RHEL)..
ClearOS was intended to be implemented in small and medium-sized businesses with a special function: Be used as a server or network gateway.
Today in TechnoWikis we will see how to install and use ClearOS completely..
ClearOS
ClearOS has an intuitive graphical user interface which is web based and has an application market of more than 100 applications to select, this is useful since we can take advantage of open source software and thus determine what applications we need and Only pay for applications and support that are required without incurring unnecessary expenses.
ClearOS features
Some of its main features are:
- Simplicity of use: Installation and configuration are simple with ClearOS since it is preinstalled on the server by default. The intuitive web-based graphical user interface will give small and medium-sized businesses the ability to navigate effortlessly in the Application Marketplace utility and download and implement the necessary applications for the necessary business processes.
- It does not require additional costs: ClearOS is preloaded on specific intelligent servers focused on SMB protocols and we can also implement it using Intelligent Provisioning. This does not add any additional cost to the platform and later, all necessary updates, patches and corrections will be provided at no additional cost through SMB.
- Focused on needs: ClearOS has an online store with more than 100 applications and services that SMEs can explore and select to install on their server.
On a corporate level, ClearOS is available for preload on HPE ProLiant ML110, ML30 and DL20 servers, allowing servers to be ready for use immediately and HPE is also managing to make ClearOS available for download and installation through Intelligent Provisioning on all ProLiant 300 series servers with which we see the alliance between ClearOS and HP.
