Cisco NX-OS vs. Fedora Linux vs. Ubuntu

It's definitely very well suited for data center environments and the scale that is sometimes required. We also manage many enterprise environments, and we almost never see Cisco NX-OS or Nexus in an enterprise environment, only specifically on the data center side. Mainly because of the lower bandwidth requirements and so on. But it depends on the hardware, since it's a software product.

For experimental use, test lab situations, or very special-purpose tasks, Fedora [Linux] is an excellent choice. We are almost exclusively a CentOS shop for our production stuff, but in labs, we take more risks with things like Ubuntu or Fedora. It's not as appropriate as CentOS for production level endeavors, but it lets us know "this is where we could be going" when we engage in r&d tasks.

If somebody whishes to be an IT professional, learning the basics of Linux is amust. Ubuntu [Linux] is one of the most beginner-friendly, widely supported, easy-to-use-relative-to-the-fact-that-its-still-linux OS on the market. As somebody who learned the basics of UNIX/LINUX on Ubuntu, it was a very good experience. It is customizable, has a lot of improvements over the years, and live up to be a viable alternative to any modern OS in 2021 as well.

• Cisco NX-OS does a great job of supporting high dense environments due to Cisco NX-OS based devices having some of the fastest packet switching performance
• Cisco NX-OS supports high bandwidth environments really well due to the high throughput links that are typically found in Cisco NX-OS network appliances
• Cisco NX-OS provides some of the best redundancy in the way of "Active-Active redundancy" via it's VPC technology. This is especially desirable in data center environments.

• frequent updates
• DNF as the package manager
• strong focus on security

• PACKAGE MANAGEMENT. You can update everything - OS installed software, you name it with either a few clicks in a GUI or a single command.
• No bloatware.
• No need for antivirus software.
• Certainly the price is right.
• My 83 year old grandmother has been using it - and because of this I rarely need to provide tech support. But I still visit my grandmother.
• You can choose from a variety of user interfaces or rock it in the terminal.
• Generally speaking, Ubuntu is as polished an OS as any you might pay for.

• I think one thing we'd like to see a bit more in the Nexus space is probably the troubleshooting features. So one would be the I perf feature and being able to test network traffic across links. Don't get me wrong, there's a lot of really good features in terms of troubleshooting, but one particular one that we like to see is where we can test network traffic. We can make sure that we have good latency, we got good bandwidth utilization as well. For us that's a big one. We've got to use third party tools to do that. So if the NXOS platform can do it, that's one of the thing we've got to do.

Incentivized

• Stability. It's good, but it's not anything like CentOS for stability
• End-user usability. It has a few glaring holes here and there with UI/UX

Incentivized

• The repository system could be a little better, as some of the software needed is not easily available there.
• Ubuntu sometimes does not play nicely or easily with some modern firmwares.
• Some people report slow responses with newer versions of Ubuntu, although we have not experienced any.

While it works, we're finding that SNAP is getting more and more annoying, so we're probably going to migrate to Debian.

NX-OS has many similarities with the traditional IOS which is quite beneficial when it comes to configuration and learning. As a native Linux system, there are a lot of tools and features that can be enabled for any use case.

This is a personal preference based on working with hundreds of client projects, I prefer Ubuntu over Fedora Linux.

I gave it 10 out of 10 because it allows me to do the work I need on a server, such as running a website and database, and making developments. In addition, thanks to its easy and useful interface during installation, it can be easily installed. In addition, thanks to its easily accessible documents, when a problem occurs, it can be solved easily and quickly.

Excellent and the best Automation capabilities with Cisco NX-OS which effectively allows easy management of different networks across the whole organization keeping all the business data secure and well managed. With its ability to detect any data threat and effectively fix the issue, Cisco NX-OS has extremely powerful options and its process monitoring capabilities are the best.

Cisco support never fails me. In terms of timely response, no one is on par with them. They really value the impact of having technical issues and potential business stoppage. Also, their support staff are well equipped with knowledge and skills and easily resolve the most common incidents. Most of the time, we can resolve an issue by just calling them once.

We did not use the managed commercial support, but instead relied on community forums and official documentation. Ubuntu is very well documented across both instructional documentation from the developers themselves as well as informal support forums [ServerFault, YCombinator, Reddit]. It's easy enough to find an answer to any question you may have

It was all pretty much automatic for our use cases. It integrates nicely with Laravel Forge, which is our primary use case.

I am much more familiar with the commands in Cisco IOS as it has been around for many more years. I know why NX-OS is a different system and can see the benefits of the fibre channel integration, but I do not understand why the commands had to use a different syntax. With the Nexus switches you don't get a choice of operating system unfortunately.

We are an all-CentOS-shop, but we've done a number of things with Ubuntu and Fedora. Most of the production CentOS machines are only there because prior to that Fedora helped to blaze the trail to get there. It's been a very good platform for testing our new ideas. Ubuntu is similarly positioned in our organization, but Fedora stacks up well in our environment.

Windows 10: Expensive, with more security problems, more difficult to keep updated and less variety of free / open source applications. Its use encourages bad information security practices. OpenSuse Linux: A different distribution at source (Suse Linux), use of rpm packages (with fewer repositories and incompatible with Ubuntu Linux dpkg packages), and whose main objective is to be a "testing ground" for its paid version / professional, SUSE enterprise Linux.

Up to now, we haven't had a major ground-shaking attack on our networks but we take no chances by using NX-OS alongside a SIEM. All endpoints and workloads are secure so I would say we have plenty of trust in their security model.

• We do have some implementations on Cisco NX-OS and Nexus hardware, and some of these are already quite old, but they are still running pretty smoothly. So they are super reliable, in my opinion. So that's one of the very positive ways it impacts companies.

• Shorter LTS means more administrator work
• Security patches help reduce vulnerabilities to help save money

• Systems administration with Ubuntu is easy with little deep knowledge about it. Docs and community publications are great resources for any task you need to perform on any Ubuntu server and the organization can save several salaries of specialized sys admins in favor of more active roles.
• Having been an Ubuntu user for many years personally, setting up new Ubuntu servers on my organization came with zero cost for me. I just deployed one instance from my hosting/cloud provider and started working right after it was running, no need to ask support or hire new staff for these tasks.
• Replacing paid options with Ubuntu have also saved thousands of dollars on Windows Server licenses. I've migrated Windows/SQL Server based systems to Ubuntu/MySQL/PostgreSQL several times during my career and saved about USD 5000/year in licenses to many of them.
