RHEL 8 (RedHat Enterprise Linux series 8) is one of the most expected and celebrated series of operating system versions in the tech community. With the launch of RedHat’s series 8 operating system, RedHat offered enhanced reliability, performance, security, and deployment to organizations. In this article, let us learn if RHEL 8 is an ideal choice for your needs and the features that set RedHat Enterprise Linux series 8 apart.

The Launch

RedHat Enterprise Linux 8 was officially rolled out in the month of May 2019 after much expectations from large organizations and the tech community. The final GA version in the RedHat Enterprise Linux 8 series is RHEL 8.10. The 8 series of RHEL OS came with numerous enhancements in the already superior security and performance.

What’s New with RedHat Enterprise Linux 8?

Security – The Top Most Priority

The Payment Card Industry Data Security Standard version 4.0 demanded more security enhancements in all operating systems. RHEL, in its 8.10 version, rolled out the SCAP security guide version 0.17.2 that complies with the required security standards. Adding to this, the Linux kernel cryptographic API version 1.4.0 has been made available to further boost data security.

More Developer Friendly

The RedHat Enterprise Linux 8 series of operating systems comes bundled with updated versions of databases and programming languages making the life of administrators and developers easier. Parts of the package include Nginx 1.2.4, PostgreSQL 16, Ruby 3.3, Python 3.12 (Python 3 and above being the minimum requirement for many applications now), and MariaDB 10.11. These updates aid developers and administrators with the latest tools and frameworks to build faster, scalable, secure, and efficient applications.

Seamless Migration to RHEL

RHEL is always concerned about migration from other distributions of Linux (distros in short). RHEL 8 comes with support to move to the RedHat Enterprise Linux 8 series either from its own RHEL 7.9 and also other distros. For RHEL 7.9, RHEL 8.10 release offers in-place upgrades to make the migration smooth across architectures. For systems migrating from other distros like CentOS (approaching EOL at the time of publishing this article), AlmaLinux, and Oracle Linux, RHEL’s 8.10 version makes the migration easier with its Convert2RHEL util (utility).

OpenSSL Tunnel Upgrade

With the latest RHEL 8.10 version, RedHat included updates to the TLS/SSL tunneling service and OpenSSL TLS toolkit to improve protection against cryptographic attacks. These improvements are a major leap to secure communications and confidential data.

Sufficient Support Phase

The RHEL 8.10 version is the end of the RedHat Enterprise Linux 8 series of operating system versions. RHEL 8.10 has entered the maintenance support phase until May 2029 providing ample time for users to migrate to the latest and more advanced RHEL 9 series. In this maintenance support phase, RedHat Enterprise Linux 8 series will still get security updates and critical bug fixes but only the RHEL 9 series will get new features.

Is Performance the Deciding Factor?

The entire RHEL series of operating systems are known for their performance and stability making it a popular choice for organizations where 100% availability and reliability are the primary requirements. RHEL 8 is a proven time tested series of operating systems that can tackle any demanding workload.

Is Security the Deciding Factor?

As discussed in detail above, RedHat Enterprise Linux 8 comes with advanced cryptographic tools and security enhancements since RedHat emphasizes more on security as most of their user base falls under the enterprise category handling sensitive data. In addition to the existing security tools, RedHat Enterprise Linux 8 will continue to get all security patches and critical bug fixes for a long time.

Is Compatibility the Deciding Factor?

RedHat Enterprise Linux 8 supports most of the modern applications, cloud environments, and also containers. RedHat being one of the major players in innovating scalable work environments like OpenShift, RHEL 8 was also optimized for compatibility with latest development tools and frameworks.

Is Future Support the Deciding Factor?

RedHat Enterprise Linux 8 came with a 10 year support lifecycle which means until May 2029 the operating system will get all support patches and critical bug fixes. This gives enough time to enjoy RedHat Enterprise Linux 8 and also to plan for RHEL 9 migration.

How to Install RHEL 8?

There are two approaches to install RHEL operating systems in general. Deploying an operating system on one device is a different process than deploying it on an organization scale. For a single device, it is as easy as downloading the ISO image and following the installation wizard. For organizations, there are specialized tools and processes to do this on an enterprise scale and RedHat has enough support and documentation already in place to make the move easier.

Wrapping Up

RHEL 8 or the RedHat Enterprise Linux version 8 comes with the cumulative years of development and expertise of RedHat. Satisfying the expectations of the community and organizations is a hard thing to do but RedHat managed to do that with its 8 series of operating systems.
