Key Improvements in RHEL 10 Over Previous Versions

1. Enhanced Security Features

Security has always been a key focus for Red Hat, and RHEL 10 takes it to the next level with several new features and improvements.

• Improved SELinux: SELinux (Security-Enhanced Linux) in RHEL 10 has become more flexible, easier to configure, and includes enhanced auditing and troubleshooting features. This allows for better security policy management compared to previous versions.
• System Roles for Security Compliance: RHEL 10 introduces integrated system roles that help businesses easily configure and enforce industry-standard security benchmarks like CIS (Center for Internet Security) standards. Earlier versions required manual configuration for such tasks, making RHEL 10 a more convenient option for compliance.
• Stronger Encryption: With updated cryptographic algorithms and the inclusion of FIPS (Federal Information Processing Standards) and TLS 1.3, RHEL 10 ensures that communications and data storage are more secure than ever before.

2. Performance Enhancements

RHEL 10 brings significant performance improvements that were missing in earlier versions, ensuring that both small-scale and enterprise-level environments perform optimally.

• Optimized Kernel: The kernel improvements in RHEL 10 provide better scalability, memory management, and scheduling compared to earlier versions, making it suitable for larger, more demanding workloads.
• Support for Modern Hardware: RHEL 10 adds support for the latest hardware, including processors, storage devices, and networking equipment. While RHEL 8 and RHEL 9 introduced support for newer hardware, RHEL 10 ensures that businesses can use cutting-edge technology to improve performance.
• Improved Resource Management for Containers: Containers have become a critical component in modern infrastructure. RHEL 10 brings more efficient resource management for containerized applications, improving performance and scalability, especially in cloud environments.

3. Advanced Cloud Integration

As businesses increasingly adopt hybrid and multi-cloud strategies, cloud integration becomes crucial. RHEL 10 further strengthens its cloud capabilities with several key upgrades.

• Seamless Integration with Red Hat OpenShift: RHEL 10 is tightly integrated with Red Hat OpenShift, making it easier to deploy and manage containerized applications and Kubernetes orchestration in cloud environments.
• Expanded Support for Cloud Providers: RHEL 10 improves compatibility with major cloud platforms such as AWS, Google Cloud, and Azure, offering businesses more flexibility when deploying RHEL across multiple cloud environments.
• Cloud Management Tools: With Red Hat Insights and Red Hat CloudForms, RHEL 10 helps organizations optimize and manage their cloud infrastructure more effectively compared to previous releases.

4. Developer Tools and Application Support

RHEL 10 continues to be developer-friendly, offering new tools and features that make application deployment and management easier.

• Application Streams: With Application Streams, RHEL 10 provides a more flexible way for developers to access and manage the latest versions of applications, reducing the need to wait for major RHEL releases.
• Support for Modern Programming Languages: RHEL 10 extends support for modern programming languages like Python 3, Go, Node.js, and Java, while earlier versions had more limited support for some languages.
• Enhanced Container Development: RHEL 10 improves container development environments, helping developers build, test, and deploy containerized applications more efficiently, with better integration of Podman and Buildah tools.

5. System Administration Improvements

RHEL 10 introduces several advancements in system administration that make managing Linux systems easier than ever.

• Red Hat Enterprise Linux Web Console: The web console in RHEL 10 has received a major update, making it more user-friendly and intuitive. It now offers better capabilities for monitoring, configuration, and troubleshooting directly from a browser, compared to earlier versions where management was more command-line-driven.
• Expanded System Roles: The system roles in RHEL 10 allow for better automation of routine tasks such as updates, package installations, and security configurations, streamlining system management, especially in larger environments.
