In our blogs, we often discuss advanced applications of Red Hat software, such as virtualization and containerization. But it’s worth zooming in on the foundation itself: Red Hat Enterprise Linux (RHEL) operating system. So, what are the new features in RHEL 10 you should know about?
Of course, RHEL 10 has far too many features to list here, so we’ll highlight four of them now and tell you how you can learn about the many possibilities of RHEL 10 a little later on.
No more config drift
One of the most important new features in RHEL 10 is Red Hat Image Mode. “With this new feature, you no longer install RHEL the traditional way, where you manually configure the operating system,” says Pieter-Jan Bellinkx, consultant at Piros. “Instead, you always deploy the same image of the operating system in a bootable container that you fully define in advance.”
“This gives you much more control over what’s deployed in your IT environment,” says Dennis Grigaliunas, sales engineer at Piros. “Every configuration is the same and immutable: you can’t change it once it’s installed unless you update the bootable container and redeploy it.” This allows you to demonstrate and guarantee exactly which software versions are installed during an audit. If something goes wrong with an installed configuration, you can roll back to the previous version with a single command.
AI-powered chatbot support
Perhaps you’ve already used Ansible Lightspeed, an AI-powered chatbot that creates playbooks for you? “Now you can also consult Red Hat Enterprise Linux Lightspeed in the Command Line Interface of RHEL 10,” says Angelo Jacobs, business development manager at Piros. “So, if you don’t know how to enable or disable certain services, or where to find certain information in RHEL 10, you can simply ask the chatbot.”
“It’s even possible to have the chatbot search through files and look for information for you,” adds Bellinkx. “Suppose you want to check when a system last booted. RHEL Lightspeed will look that up for you in the log file. RHEL Lightspeed even powers package suggestions to add when you’re building a RHEL 10 image in the Red Hat Insights image builder package.”
It’s important to note that the chatbot currently only draws its knowledge from official Red Hat documentation, and that doesn’t even include the many thousands of Red Hat Access articles from the Red Hat Customer Portal. That will change in the future. The potential is enormous.
Quantum-proof security
These are already two innovative features, but Red Hat Enterprise Linux 10 offers many more. Dennis Grigaliunas: “I’m thinking, for example, of the support RHEL 10 already offers for post-quantum cryptography: algorithms that protect data and communication against security breaches with quantum computers.”
Baseline x86-64-v3 microarchitecture
RHEL 10 also requires a significant technical change. “Every CPU running RHEL 10 must at least support x86-64-v3 as a baseline,” says Bellinkx. “Older CPUs that don’t have that instruction set are no longer supported. At Intel, support extends back to Haswell processors, at AMD to Excavator.”
