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.

Empowers collaboration through streamlined integration and extensive documentation
Improving Red Hat Enterprise Linux (RHEL) can be tough, however, a significant area is collaboration tools. We have many Windows users that use Outlook and Skype or Teams to collaborate on our network. They want Linux desktops due to the fact that they want to use containers. Their biggest complaint is, 'I need two workstations to do my container work and one to collaborate.' If somehow RHEL can start introducing or collaborating with Teams and Outlook so their users can work with their Windows peers, that would be great. But I don't think that's available yet. Regarding pricing, setup costs, and licensing, there needs to be more of an education piece to it. For instance, when purchasing 10 or 100 node licenses, they could suggest, 'We also offer this 1,000 node license instead, and it'll save you specific amounts.' Just more education on their offerings would be helpful, because usually, we're coming out with the requirements, and then they just provide it to us. They could inform us about saving by bundling it differently or using alternative approaches.

Has delivered expert training and enabled smooth migrations using automated deployment tools
SUSE Linux Enterprise is a mature and reliable platform, but there are areas where it can be improved. Modernizing the system management tools is important as many users appreciate YaST for its centralized management, but there is a growing demand for more modern, web-based, and modular tools. The introduction of tools such as Agama, a web-based installer, and Cockpit in newer releases is a step in the right direction.SUSE has made progress with multi-Linux support, allowing organizations to manage and support not just SUSE systems but also other distributions such as Red Hat and CentOS; continuing to expand these capabilities, especially for hybrid and multi-cloud environments, will help organizations manage diverse infrastructure more effectively. Security is a top concern, and further strengthening default security policies, simplifying compliance management, and integrating advanced vulnerability management tools would be a valuable improvement.
