If you are a Linux lover then here is an exciting news for you as Red Hat has announced “Red Hat Enterprise Linux 8“. The main focus of this main release of Red Hat Linux is the emerging and current worlds of enterprise IT. In this article, we will see what are the main features and things which you should know about Red Hat Enterprise Linux 8.
As the IT world is growing at a very rapid pace we need a foundation which can span over the latest emerging technologies like the cloud to traditional ones.
Red Hat Enterprise Linux 8 Beta helps IT teams to optimize and extract added value from existing technology investments, helping to bridge demands for innovation with stability and productivity.
7 Things You Should Know About Red Hat Enterprise Linux 8
1. Application Streams
Red Hat Enterprise Linux 8 Beta introduces the concept of Application Streams to deliver userspace packages more simply and with greater flexibility.
Userspace components can now update more quickly than core operating system packages and without having to wait for the next major version of the operating system.
IPVLAN is one of the main features in RHEL 8 through which more efficient Linux networking in containers is possible. It helps in connecting containers nested in virtual machines (VMs) to networking hosts with a minimal impact on throughput and latency.
It also includes a new TCP/IP stack with Bandwidth and Round-trip propagation time (BBR) congestion control.
RHEL 8 is more secure and it brings hardened code and security fixes to enterprise users. The main objective of Red Hat with RHEL 8 is to deliver a more secure by default operating system foundation across the hybrid cloud.
OpenSSL 1.1.1 and TLS 1.3 are both supported in Red Hat Enterprise Linux 8 Beta along with System-wide Cryptographic Policies.
4. Linux containers
Red Hat’s lightweight, open standards-based container toolkit is now fully supported and included with Red Hat Enterprise Linux 8.
Built with enterprise IT security needs in mind, Buildah (container building), Podman (running containers) and Skopeo (sharing/finding containers) help developers find, run, build and share containerized applications more quickly and efficiently, thanks to the distributed and daemon-less nature of the tools.
5. Systems management
System administrators are in luck with Red Hat Enterprise Linux 8 (RHEL 8) as Red Hat has made it easier for them like a single and consistent user control panel through the Red Hat Enterprise Linux Web Console.
This provides a simplified interface to more easily manage Red Hat Enterprise Linux servers locally and remotely, including virtual machines.
RHEL 8 also has “Composer” which will make it very easy to build and deploy custom images across the hybrid cloud for both new and experienced Red Hat Enterprise Linux users. It also has Yum 4, which will provide faster performance and fewer installed dependencies.
6. File systems and storage
RHEL 8 has introduced “Stratis“, which is a volume-managing file system for more sophisticated data management.
Stratis abstracts away the complexities inherent to data management via an API, enabling these capabilities without requiring systems administrators to understand the underlying nuances, delivering a faster and more efficient file system.
The new kernel in RHEL 8 supports 5-level paging, with the help of new P4d_t software page table type.
Earlier, in RHEL 7, existing memory bus had 48/46 bit of virtual/physical memory addressing capacity, but now in RHEL 8 these limits have been extended to 57/52 bit of virtual/physical memory addressing with 128 PiB of virtual address space and 4 PB of physical memory capacity.
