Red Hat Enterprise Linux 9 breaks cover

Enterprise IT vendor Red Hat has officially released version 9 of its Linux distribution, which is aimed at enviroments ranging from hybrid clouds to organisations' network edges.

Red Hat Enterprise Linux (RHEL) 9 is the first release built from the the CentOS Stream.

The latter is a distribution that tracks just ahead of RHEL to garner feedback, code and feature updates that can be backported to the commercially supported operating system offering.

RHEL 9 will be available on Amazon Web Services, integrating with the cloud giant's Graviton processors to provide better price-performance for a wide range of workloads in EC2.

Microsoft's Azure cloud will also have RHEL 9 availability, and able to run key applications like SQL Server and support .NET development.

For multi-tenant applications in data centres, RHEL 9 provides mitigations against hardware security vulnerabilities like Spectre and Meltdown.

Administrators can also further bolster security with userspace processes creating memory areas that can't be accessed by malicious code.

Other security features introduced include Red Hat's integrity measurement architecture which uses digital hashes and signatures to detect rogue infrastructure modifications.

Live patching of the Linux kernel is also supported on RHEL 9, and it can be automated across large distributed deployments.

Beyond cloud provider market places, RHEL 9 will be made available through the Red Hat Customer Portal.
