Red Hat Enterprise Linux 9.1 and 8.7 Released

Prepared by: Giray Baha Kezer – Sekom – SDX & Cloud Technology Engineer

According to Forrester’s 2023 forecasts, 40% of global companies will adopt cloud-based strategies. This shift is further driven by the transformation towards cloud-native software development and orchestration solutions like Kubernetes. The underlying reason behind this trend is the need to manage applications and workloads more efficiently and effectively. Continuing on this path, Red Hat remains committed to supporting its customers’ cloud-based transformations with more secure and stable solutions within a hybrid cloud infrastructure.

The Red Hat Enterprise Linux 9.0 and 8.6 releases, launched in May, were developed in line with these strategic objectives. Recently, Red Hat released versions 9.1 and 8.7, with security being a key focus in these updates.

Red Hat Insights now includes malware detection capabilities, making Red Hat Enterprise Linux systems more resilient against known vulnerabilities and malicious breaches. Additionally, Sigstore technology has been integrated with Red Hat Enterprise Linux native container tools, allowing users to leverage code signatures like local keys. This contributes to enhanced security in hybrid environments.

Furthermore, versions 9.1 and 8.7 facilitate automation through Red Hat Enterprise Linux system roles, streamlining operational processes.

Additionally, the new releases include updates related to SQL, Red Hat Enterprise Linux Satellite Smart Management, Insight, and Workstation. For a detailed review, you can refer to the Red Hat documentation:
