Head Of IT at a financial services firm with 1,001-5,000 employees

Long-term server platform has supported secure banking operations and simplified virtualization

Oracle Solaris is a very good operating system. Most of the time, we do not need to change or replace any configuration. If at any point in time we need to change something, it is really simple and a user-friendly environment. Although it is a CLI, Oracle introduced a GUI environment with Solaris 11.5. Currently, 11.5 has the operating system GUI as well as the CLI. The technical persons working on the operating system most of the time prefer to work on the CLI. It is actually really good and easy to use. As it is a server-level operating system, most of the time you do not need any extra features in the operating system because you are not using the operating system on home machines, desktops, or laptop machines. The extra features are not needed if we are talking about the enterprise level or an official operating system.

Automation has transformed daily operations and supports secure, continuous infrastructure

When considering improvements to Red Hat Enterprise Linux (RHEL), I see one primary area. Within your portal, if you provided more study material along with demonstrations similar to the sessions we are attending, which feature a user-friendly guide, you could incorporate this into your Red Hat console. When I want to install an agent or something else, typing in the console should provide me with clear step-by-step instructions. Throughout the years, installation steps have been available, but regarding AI agents or Ansible automation, I need to verify whether clear information exists. Including this information would be beneficial. Additionally, if you add the sessions that have occurred to your portal or another location, this would help us review them multiple times to gain better understanding. Time is limited, and many sessions occur simultaneously, making it impossible to attend everything. Making these sessions available on your website would be very helpful.
