Room For Improvement

Users seek RHEL improvements in CLI, third-party integration, licensing costs, security, GUI appeal, documentation, and cloud-native support.
VMware vSphere needs cost management improvements, enhanced integration, intuitive UI, better support, and simplified setup for broader appeal.
Addressing these limitations would significantly enhance the operating system's flexibility and efficiency.
Senior DevOps Engineer at a financial services firm with 10,001+ employees
The built-in security features of Red Hat Enterprise Linux were insufficient for our needs, necessitating the implementation of supplementary security measures.

Information Technology Architect at Central Bank of India
The cost changed from perpetual to subscription, and there is a need for alternative solutions.
Manager of Solutions and Support at Esconet Technologies Pvt. Ltd.
Another area is the stability during upgrades from older versions to newer versions, where we face issues.
Manager of Systems at Sir Syed University of Engineering and Technology
 

Setup Cost

Red Hat Enterprise Linux is valued for support and enterprise-grade features, but smaller entities find its pricing high.
VMware vSphere's high pricing and licensing complexity are balanced by praised features like centralized management and support services.
It may be considered expensive compared to other solutions like CentOS or Ubuntu, which offer some of the same features without additional costs.
Cloud Infrastructure Architect at a healthcare company with 10,001+ employees
Its pricing has room for improvement because it's more expensive in the local market due to purchasing power parity in India.
Cloud engineer at a tech services company with 11-50 employees
Windows Servers base their cost on the number of users and have high licensing fees, while Red Hat Enterprise Linux offers free versions alongside its paid, supported versions.
Senior DevOps Engineer at a financial services firm with 10,001+ employees
Many customers are trying to avoid it due to its high cost.
Technical Assistant at EOCD
Costs significantly increased from perpetual to subscription, with prices rising by two to three times over three to five years.

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.

Reliable virtualization has supported smooth DR drills and efficient resource allocation
VMware vSphere has proven to be robust in nature, and the new features are quite acceptable. The new features in NSX network switching make it more useful in the reliability management of data centers. vMotion has helped my organization's business continuity strategies during our planned DR drill activity. The migration of VMs from DC to DR is quite smooth with respect to the network link. I assess the impact of VMware vSphere's High Availability feature on my infrastructure resilience as effective during DR drill activities and firmware upgrades, which we perform every six months. During those times, we rely on maintenance mode of several servers, and HA works properly. I have nothing to complain about. We have utilized VMware vSphere's Distributed Resource Scheduler effectively. Even though we have over-provisioned the vCPUs, it efficiently manages the CPU cores and memory of the servers intelligently, so I am not experiencing any bottleneck in resource utilization. Distributed Resource Scheduler has affected my resource allocation performance positively, providing a 20 percent advantage over my old hardware.
