Both of these tools are used for optimal management of Linux servers.

Red Hat has introduced different tools for managing Linux servers and Linux operating systems, so that all the processes can be implemented in the servers in the shortest possible time.

Since both of these tools are used to manage Linux servers and Red Hat operating systems, the question that arises most for users is the exact difference between these two?

The first point about the Red Hat Satellite tool is that it is only used for Red Hat Linux servers, but Red Hat Ansible has a variety of applications and can be used for all types of Linux. It can be said that Red Hat Ansible is not limited to Red Hat Linux.

The second point about Red Hat Satellite is that this tool is mainly used for Package Management or central and automatic server updates, but Red Hat Ansible has more capabilities. That is, in addition to central updating, Red hat Ansible provides more extensive facilities to organizations. In fact, Red Hat Ansible is a platform for automating all processes in Linux servers and does not focus only on the central update of Linux servers.

A point that should be considered is that the possibility of updating is one of Ansible’s capabilities, but it is better to use RedHat Satellite in this case. Because the versions and authenticity of the packages, i.e., the received updates for the operating system and its components, are carefully checked by RedHat Satellite, and with its help, you can even test the package before installing it.

In general, Ansible provides wider capabilities to organizations, and Red Hat Ansible’s performance is different and it can manage more tasks. Because Red Hat Ansible is actually an automation system and in addition to updating, you can install software on servers, change the software configuration, change IP, etc.

Difference of Ansible with Red Hat Ansible

One thing that should be noted is that Red hat Ansible and Ansible have similar performance. But Ansible is an open-source software. Also, it is not supported and has more limited access. On the other hand, Red Hat Ansible provides users with more features because it is supported by Red Hat. For example, to run some tasks in Ansible, we need to create the configuration file manually. While in Red Hat Ansible, there are a number of ready and pre-tested scripts that greatly reduce the risk. 

In general, it can be said that if you only need to update Red Hat Linux servers and do simple and basic tasks, you can use Red Hat Satellite. But if you intend to automate all the administrative and executive processes that are required in Linux servers and there is variety in the type of Linux, Red Hat Ansible is a better option.

CentOS Migration to Red Hat Linux Enterprise 

What is CentOS? 

CentOS stands for Community Enterprise Operating System. CentOS is a sub-branch or distribution of many sub-branches of the Linux operating system. This open-source platform provides its users with a free platform to continue their activities under the supervision of the community of online experts.

CentOS started in 2004 as an independent revolution supported by online forums. The structure of this commercial operating system, which is used in the servers of small and large businesses, originates from the resources that have been made available to the public for free by Red Hat.

CentOS officially merged with Red Hat in 2014 while continuing its activities. But at the same time, it continues its activities independent of Red Hat’s commercial operating system, Red Hat Enterprise Linux.

In general, it can be said that CentOS is a free version of RHEL, lacking the technical support provided by Red Hat. On the other hand, CentOS can meet the needs of organizations for a secure server to a high extent.


Red Hat Terminates Servicing CentOS 

Since many organizations are using CentOS versions, currently, the major concern plaguing these organizations is the announcement made by Red Hat recently. Red Hat will support the CentOS8 version until December 2021 and the CentOS7 version until June 2024.

This might be very concerning for many businesses that have built their servers based on CentOS. Because after this period, it will not be possible to update the services stably, and we will mention some of these problems in the following.

Non-Migration from CentOS to Red Hat Enterprise Linux

First of all, you should know that Red Hat has cut eight years from the time set to support CentOS 8, and according to the recent announcement, CentOS7 will only be supported until the middle of 2024. In fact, after the end of 2024, CentOS is no longer as reliable as before and may be vulnerable to new viruses. Also, it will not be possible to update software such as Apache, MYSQL, etc. stably, and the services installed on this operating system will suffer from security vulnerabilities.

Main reason for selecting Red Hat Linux Enterprise for Migration 

The main reason for selecting Red Hat Linux Enterprise operating system as an alternative to CentOS operating system compared to other available choices such as Ubuntu, Fedora, Debian, etc., is easy migration, high compatibility without data loss, and running configurations. Also, since CentOS originates from Red Hat and these two operating systems are highly similar, a familiar environment will be provided for the users of this system, resulting in the minimum waste of energy and time in learning this operating system.

According to the above, Red Hat Linux Enterprise can be the best alternative for the organizations that used CentOS before, because this company is the owner and supporter of CentOS and known the customers’ needs well. It also knows that by offering the Red Hat Linux Enterprise product, it has solved these problems and needs.

How to Migrate from CentOS 6,7,8 to Red Hat Enterprise Linux

According to the recommendation of Red Hat, for migrating from CentOS to Red Hat, you should choose your CentOS version according to the Red Hat version.

For example, if you are using CentOS6, it is better to choose Red Hat6 for migration and upgrade Red Hat after complete migration.

The following figures show the migration roadmap from CentOS6, Oracle linux 6, CentOS7, CentOS8, Oracle linux 7, and Oracle Linux 8 to Red Hat Linux.
