Red Hat Enterprise Linux (RHEL) is a commercial Linux distribution with a history of more than ten years (initially released in 2000). It often uses on mainframes and supercomputers in addition to ordinary PCs and general servers. The excellent stability makes it widely used in many infrastructure-level servers. It provides support for multiple architectures such as the 64-bit ARM, x86/x86_64, Power PC, and IBM z Systems. Red Hat uses strict trademarked rules to limit the free redistribution of its officially supported version of RHEL, but RHEL’s source code still provided free of charge. Third-party derivative versions can be built upon the removal of non-free components such as Red Hat trademarks, such as community-supported commercial forks such as CentOS and Scientific Linux, as well as Oracle Linux.
The RHEL team announced the release of RHEL 7.7 Beta. RHEL 7.7 Beta includes a range of enhancements and bug fixes to better provide a powerful and flexible platform for hybrid cloud computing. Major updates include support for the latest generation of enterprise hardware and remedies for recently disclosed microarchitecture data sampling (MDS)/ZombieLoad vulnerabilities.
The beta also includes performance enhancements to the network stack and the ability to offload virtual swap operations to network interface card (NIC) hardware. The value of these capabilities also improves the operation of Red Hat OpenStack platforms and Red Hat OpenShift deployments, all built on top of Linux, using virtual switching and network function virtualization (NFV).
In addition, as part of the Red Hat Enterprise Linux subscription, RHEL 7.7 Beta users can access Red Hat Insights by default. Red Hat Insights includes Red Hat’s extensive expertise in providing enterprise Linux deployments, providing software-as-a-service (SaaS)-based predictive analytics solutions that help enterprise IT teams better assess and mitigate systems before production impacts potential problems.
