What is Red Hat Enterprise Linux?
Red Hat Enterprise Linux, known as RHEL, is a Linux distribution designed specifically for business environments. Developed and maintained by Red Hat, it offers a stable, secure and compatible platform with critical applications that organizations depend on today. Unlike community distributions, RHEL is delivered by subscriptions that include access to updates, security patches and specialized technical support.
Main advantages of RHEL
- Stability and performance: Each version of RHEL goes through a rigorous certification process that ensures compatibility with hardware and business software.
- Business level security: Includes SELinux, timely security updates and compliance tools such as OpenSCAP.
- Technical Support 24 / 7: Customers have access to Red Hat engineers who can solve real-time incidents.
- Updates and certified patches: The repositories are signed and validated, reducing the risk of introducing vulnerabilities.
- Integration with OpenShift and Kubernetes: RHEL is the recommended basis for deploying containers and orchestrating hybrid cloud applications.
- Deployment flexibility: It can be run on physical servers, virtual machines, public cloud platforms (AWS, Azure, Google Cloud) and in edge environments.
Typical cases of use
RHEL is adapted to a wide variety of business scenarios. Among the most common are:
- Database platforms such as Oracle, Microsoft SQL Server and PostgreSQL.
- ERP and CRM applications such as SAP, Salesforce and Microsoft Dynamics.
- Development environments and tests that require accurate production reproduction.
- Virtualization infrastructures with KVM or VMware, where a light and safe hypervisor is needed.
- Web and API services that benefit from the management of updates without long inactivity times.
- High-performance computing (HPC) and analysis of large data volumes.
How to start with RHEL
- Download the evaluation version: Red Hat offers a 60-day free trial copy from its developer portal.
- Create an account on the Red Hat client portal: The record allows access to downloads, documentation and management tools.
- Select the installation medium: You can use an ISO image for physical installation, a qCow2 image for virtual machines or a market image for cloud suppliers.
- Run the installer (Anaconda): Follow the graphic wizard or text mode to partition disks, configure network and define the root user.
- Record the system: Use the command
subscription-manager registerto associate the server to your subscription and enable the appropriate repositories. - Apply initial updates: Run
yum update(ordnf updatein more recent versions) to make sure you have the latest patches. - Install optional management tools: Consider adding
cockpitfor web administration orsatellitefor management on a scale of hundreds of nodes.
Good administration practices
For the maximum benefit of RHEL, follow these recommendations:
- Keep the system subscribed and enable the security repositories to receive automatic updates.
- Use SELinux security profiles suitable for each server role and review the records with
ausearchandauditd. - Apply snapshots or virtual machine images before applying critical changes, facilitating the reversal if necessary.
- Take advantage of Red Hat Insights for predictive analysis of possible errors and optimization recommendations.
- Document service settings and use configuration management tools such as Ansible or Puppet to ensure reproducibility.
Conclusion
Red Hat Enterprise Linux remains the preferred option for companies that require a reliable, safe and supported operating system by a support and certification ecosystem. Its focus on long-term stability, integration with container technologies and hybrid cloud, and the availability of continuous updates make it a solid basis for any critical workload. Whether you are starting a new infrastructure project or looking to modernise your current environment, RHEL offers the tools and confidence needed to achieve business objectives.
