CIS Hardened Container Image Level 1 on Ubuntu Linux 22.04 LTS

Ubuntu Linux is my operating system for daily use, and because I am related to networking operations, I prefer Linux over Windows. The FortiClient in Windows is very limiting and the IT department most of the time doesn't know how to open certain ports or are very limited in their skills with FortiClient, so I have more freedom to open ports and run some services with it.

One of the best features of Ubuntu Linux is that if I need something, I just download it. Everything I need I could search for on the net and just download it and use it, whereas Windows is more problematic.

Ubuntu Linux's rapid support and extensive documentation are fine to me. Every time I need to do something, I find well-explained documentation about the process, so I have no complaints about the documentation or the info about how to do it.

I always use just the LTS versions of Ubuntu Linux, but I found recently some software that needs the 20.04 version, which is out of the support lifecycle, and those systems are needed by us, causing a problem when I tried to upgrade. The systems stopped working and it was a disaster, as they support the LTS but the old ones, and when I need to update some packages, they are out of the support system support cycle.

I have used Ubuntu Linux for maybe 12 years.

I have never rated the support or customer service of Ubuntu Linux as I have never used it.

Positive

My experience with the pricing for Ubuntu Linux is that I always use the free version, so I never paid for any installations or support.

I have not used Ubuntu Linux's cloud-init capabilities for configuring or managing instances in cloud environments.

I don't know of any things that could be better with Ubuntu Linux, as everything works fine.

On a scale of one to ten, I would rate Ubuntu Linux a 10 plus.

I basically work only in Linux because I'm a Linux system administrator, so I preferably only work in Linux systems.

I'm basically a system admin in the Linux domain, and I work in EC2 instances only. My work revolves around Drupal websites, as I work in an organization that primarily focuses on Drupal websites. To run those Drupal websites, we use EC2 instances as our server, so that is the main expertise I have.

I am not exactly in development because I'm in operations, but that can come into the role itself because I'm involved in operations, not the development team itself.

I am currently using Ubuntu Linux internally in my company, and for customers too.

For long-term support, it has been good because in most enterprise environments, people still use Ubuntu Linux sixteen, which is quite obsolete now. Other enterprise versions do not support obsolete systems, so supportability is good in terms of Ubuntu Linux. For sustainability, it's quite a significant point of view for every organization. For us, Ubuntu Linux is the preferable way.

The documentation for Ubuntu Linux is quite extensive; you'll gain the information that we intend to, but you need to have the ability to navigate through the documents. That's very good knowledge that they provide, and that's a solid point from me.

Most people prefer Ubuntu Linux. If they want any specific tooling, such as SAP applications, people use SUSE or Red Hat for specific hybrid infrastructures related to security. If people want reliability and flexibility to run anything, they use Ubuntu Linux. Compatibility with hardware is very good with Ubuntu Linux; I have seen very few issues regarding compatibility.

The first advantage is that it's price-efficient as far as the enterprise version is concerned. There's not a very big difference, but if you are running ten to twenty thousand fleets, those few dollars could mean a lot for some organizations. The second advantage is compatibility with any hardware, and the third is reliable OS updates and support.

Any Linux is scalable in terms of capacity, and on a day-to-day basis, we use scalability options with the help of Kubernetes clusters. It's very convenient to scale it up to any form needed because Ubuntu Linux itself is a lightweight OS.

For us, Ubuntu Linux is the preferable way. For others, it might not be, so that is quite a subjective matter itself.

The pinpoint of the problem is that they take time because they need specific information. We need to go to AWS first, and then they'll contact the Ubuntu Linux support team itself. This creates a two-way hop for us, which is why it's not that great. It's not really Ubuntu Linux's problem but rather the way we are accessing Ubuntu Linux.

The migration part when migrating an application or one version of Ubuntu Linux to another is quite hectic. During the process, one or many applications might crash. That is something they could handle themselves, but I don't think that's something Ubuntu Linux will look into. During a migration project that I was handling, Ubuntu Linux was not completely compatible for the migration process from one application to another. This is an area they could improve in migrating from minor versions to major versions.

I have been working with Ubuntu Linux for three years now, and I've used different flavors from sixteen to twenty-two, and now it's the latest focal, which is twenty-five.

For me, it's quite simple because we don't frequently update the stack itself. For many people, it is subjective because if you're running very dynamic applications, not only on Ubuntu Linux but any Linux systems, it can be quite subjective based on the applications they are using. If updates happen frequently, no system would be stable without tuning it every time there's an update. For us, it's quite reliable in terms of stability.

Any Linux is scalable in terms of capacity, and on a day-to-day basis, we use scalability options with the help of Kubernetes clusters. It's very good as there is no technical reasoning against it because Ubuntu Linux itself is a lightweight OS, so it's very convenient to scale it up to any form needed.

I am mostly dealing with Ubuntu Linux  systems currently. Instead of using Windows, we have been given Ubuntu Linux , and that is what we have been using for our day-to-day activities. When we were due for an update, we switched from Windows to Ubuntu Linux, which has been a few months ago.

I believe everything works faster than it used to in Windows. I have never experienced a crash on Ubuntu Linux. The system works great with perfect stability.

There were some initial issues with logging into the system, but I do not remember much about them now. Currently, there are no issues. I do not think Ubuntu Linux has a robust documentation library.

I am probably not in a place to say much about this as I have only been using it for a few months.

I have never experienced a crash on Ubuntu Linux. The system has been completely stable, which makes it deserve a perfect score. The system works great without any crashes.

IT helps at times, so that is who we reach out to. It was our IT support person who helped us out. We have never had to reach out to Ubuntu Linux directly.

Positive

I have not been working with Microsoft products recently. I have been working with other tools. I have not touched any Microsoft tools this year. Last year, I used Microsoft products minimally.

I am not sure about the return on investment. The higher-ups would likely know if they saved money since Microsoft is licensed while Ubuntu Linux does not require a license.

There are many differences between Ubuntu Linux and Windows as they are totally different systems. You need to have more knowledge about Linux before using Ubuntu Linux. Although it is designed as a desktop system, basic knowledge is still required. Windows can be used by any layman, which is the main difference.

I do not know much about security breaches or potential issues. The Wi-Fi and wireless capabilities work perfectly fine.

Excluding the learning curve, I would rate it a 10. However, considering the learning curve, I would give it a six or seven.

My advice would be to have patience.

Overall rating: 10 out of 10.

I use Ubuntu Linux  for application servers in my daily operations.

I run web applications on Ubuntu Linux .

For application servers, I find Ubuntu Linux very useful.

I have a project on Ubuntu Linux that uses Nvidia graphic cards for AI purposes, such as Google Maps, where car cameras collect images while running on the road to build a map and recognize shop names and locations.

I find Ubuntu Linux to be a stable operating system and open-source, supporting almost all features as expected for an operating system, and it's widely supported by any open-source applications.

It is widely supported by almost all applications.

Ubuntu Linux continuously improves itself; it supports almost every new feature, and AI projects benefit from these developments, as well as every web-based project due to support for at least three or four web platforms such as Apache and Nginx.

Automation is very important for wide deployments, and Ubuntu Linux supports a lot of automation features, making it easy to deploy hundreds of applications. While Linux platforms are generally difficult to manage due to shell applications and lots of text files, automation handles these challenges and allows monitoring of the deployment process. This kind of development needs to be done, and the GUI could be better.

The GUI could be improved for beginner users.

For beginners, the GUI may be improved, but pro users use automation tools, scripts, and other options, so they don't need easy GUI tricks.

I have been using Ubuntu Linux for at least 5 years.

The initial setup deployment takes less than an hour.

During these 5 years, I have faced some minor issues with Ubuntu Linux, but not a major downtime.

Ubuntu Linux is very scalable.

Before working with Ubuntu Linux, I evaluated most other Linux operating systems such as Red Hat, SUSE, and others.

Red Hat is a very professional operating system, and many operating systems use Red Hat-based code, but I find Ubuntu Linux to be a bit easier and more widely used, possibly due to Red Hat's license limitations.

For the setup of Ubuntu Linux, I would rate it eight out of ten for ease.

Ubuntu Linux is almost free, but it has some professional services that require payment if you choose to use them. For a low-cost application server, Ubuntu Linux is a good choice, or for an enterprise-wide scalable operating system with professional services, you can select Ubuntu Linux at a reasonable price.

I may share a review on other Linux or operating systems such as Rocky, Kali, Oracle, and SUSE in one or two months.

Currently, approximately 2,000 users are working with Ubuntu Linux in my company.

I plan to increase the usage in the future.

I strongly recommend Ubuntu Linux to most customers.

I would recommend it because it is very stable, supports almost every new feature, and almost all open-source projects, with easy support available from the web and professionals.

I rate Ubuntu Linux 9 out of 10.

I use Ubuntu Linux  as a workstation to check my emails, to connect to people, to use Teams, to send mails, and to browse everything, similar to how we use Windows.

I use Ubuntu Linux  as a replacement for Windows for everything. I use Teams, emails, Zoom , AnyDesk , and UltraViewer on it.

For system administration, I find it useful to connect to my Linux servers directly from the command line, and I create my virtual machines using VMware Workstation .

In terms of security, I am satisfied with Ubuntu Linux and I can rely on its security features more than I can with Windows.

There might be some features or limitations I would want to see improved, but I cannot think of any specific ones right now. It is easy to use.

The booting of Ubuntu Linux should be faster because I only have two minutes when I have calls, so it should complete more quickly.

I have been working with Ubuntu Linux for four years.

I have not faced any challenges with Ubuntu Linux such as integration or any other challenges.
