вЂњUnlike other major releases, this is going to feel familiar,вЂќ he said. Previously, a new release would have a host of new tools for admins to learn, which could be a headache for those working in IT environments that continue to scale out in size and complexity, according to McCarthy. One of the other chief selling points of RHEL 9 isnвЂ™t a new feature as such, but it marks a departure from the companyвЂ™s usual practice: Red Hat has gone out of its way to change as little as possible about the basic management tools. TheyвЂ™re just building in the features to the core product.

вЂњSUSE creates very specific edge products that will join the portfolio of their standard Linux offerings,вЂќ he said. Red HatвЂ™s approach differs sharply from some of its open-source-edge competition, according to McCarthy. The company also announced new containerization options, including standardized universal base images in вЂњmicroвЂќ and вЂњminimalвЂќ form factors, meant for development of applications designed for constrained devices-again, a new feature set that could make RHEL more attractive as an edge operating system. Red Hat announced native support for Smart Card authentication via web console, extra security profiles designed to simplify compliance with standards like HIPAA and PCI-DSS, more detailed single-sign-on logging and integrated OpenSSL 3. Security and compliance got some important new features in RHEL 9 as well. вЂњ realizing that вЂ™s being put into environments where it hasnвЂ™t been before.вЂќ вЂњItвЂ™s scalability in a different way than people used to think about it in a data center,вЂќ he said.

Many of those features make RHEL 9 better-suited to use in edge environments, according to IDC vice president Dave McCarthy, who noted that automation seemed to be a particularly important focus in the new version. The key new management features include enhanced web-console performance metrics for easier diagnosis of problems, live kernel patching without the need for downtime, and an easier way to create new OS images. But the biggest news might be the lack of changes to the management and administration tools from the previous version, which could make adoption fairly painless. Red Hat Enterprise Linux version 9 released today as a beta, bringing about a dozen major new features focused on security and compliance, simplified management and automation.
