Red Hat Enterprise Linux 8, more commonly abbreviated as RHEL 8, was released on May 7th, 2019. This release came swiftly after IBM acquired Red Hat for $34 billion on October 28, 2018.
In the current age of dynamic IT operations, regularly managing and overseeing your IT functions is a critical business asset. To deliver ambitious and competitive advantages, IT organizations should shift from traditional infrastructure operations to flexible environments.
Red Hat Enterprise Linux 8 gives an intelligent, stable, and security-focused foundation for advanced and agile business operations. Maintaining consistency across infrastructure enables you to deploy applications, workloads, and services using the equivalent tools, regardless of the location they are present in. As a result, you can implement and operate the enterprise hybrid cloud environment your business needs faster and with much less effort.
Key features and advantages
The Red Hat Enterprise Linux 8 provides you more control, confidence, and freedom to innovate, and RHEL 8 reduces the friction and cost involved in cloud deployment while accelerating time to market for crucial business workloads. Enhanced usability and familiar, automatic deployment and management interfaces help Windows, and Unix users get started with Linux more smoothly. Complete, native automation lets you deliver services faster and more consistently across the cloud infrastructure.
Streamlined and Modernized access to high-quality open source development tools assists you to build and launch new products more rapidly.
While RHEL 7 supports a maximum of 64TB of physical memory, RHEL 8 supports up to 4PB of physical memory. That’s quite an upgrade from the old traditional systems.
The sosreport can now report any loaded extended Berkeley Packet Filtering programs and maps in RHEL 8 version.
Smart operating system
Red Hat Enterprise Linux 8 provides built-in manageability and integration with Red Hat management and automation products. Every active Red Hat Enterprise Linux subscription includes access to Red Hat Insights. Red Hat Insights addresses your problems with predictive operating system analytics that let you rapidly identify and rectify threats to availability, security, stability, and performance.
