Ubuntu Linux Reviews

I use it for self-service applications, containerization, security, and backup. There are so many use cases; I can't mention everything.

I find the terminal valuable for pasting some commands and using some software as well. It's probably called a terminal and shell environment.

I use Ubuntu Linux for server administration and to manage network traffic. I set up a Linux server and router with all traffic through ease. I could limit the band rate limits of users in university. These are the main use cases. I also used Ubuntu with ZoneMinder Software. It's open-source software and we use about 700 CCTV cameras, which are IP-based. We deployed this on our servers for use on our own two operating systems. Other use cases include using it with the base cloud. I set up an openness patch on the Ubuntu Operating System. I'm familiar with Bash Scripting, Python Scripting, and the system programming in C and C++, but C and C++ programming languages are not my recent activities. Most of my working system is Linux Scripting or with Python. Actually, I'm recently working with Ansible to automate my jobs and my Linux experiences. Ubuntu provides for all of these activities. I also used it for OpenStack.We are hosting providers and a service company. Half of our services are based on CentOS, but they are going to migrate to Ubuntu as they are using services that Ubuntu provides. We are going to use Ansible to manage Ubuntu servers using the provided automation. We have been deploying OpenStack in an industrial IT company in Iran and now we are going to add special storage as a block device for our private cloud in Iran.

Many years ago, I used to compile Linux Kernels and operating systems. In those days, I had a lot of problems with compiling from scratch and it was so time-consuming. When I got a job in the industry, I faced new problems. So I found that may be using a new operating system may be a way forward, and that is how I came to start using Ubuntu. Performance, security and manageability are my main reasons for choosing Ubuntu. For performance, I can tune as needed. The security aspect has good features and support. There is a free security bug system. This is really good and helpful for the organization, to identify any security issues in the system. We have about 20 to 200 users in our company. Most of them use Ubuntu as a base system and all of, or may actually half of our servers are Ubuntu based. We use OpenStack code, and we have a data centre with about 150 servers of DL306 HP and set up Ubuntu on them.

We can use the solution for browsing. We can also use it as a server and deploy and configure it as a file or web server. The use case depends on the user. I use it to deploy something which I want to test out. If I have to test out ELK Stack, I might use Ubuntu because it’s free.

The GUI is user-friendly.

I currently have the Ubuntu server edition installed across 200 Dell Servers running various projects, applications, and virtualization technologies. I have 70 Ubuntu Desktop editions running throughout my office, we have made a switch from Windows and will not be going back as the stability is incredible on an Ubuntu setup.

The installation is quickly done, the software is easily installed, and deployment can be automated across the workstation and server estates.

My support team also feels far more in control of their destiny when it comes to developing minor tools on the fly for their needs. 

It has improved our ability to carry out maintenance without downtime as migrating services between server environments is largely seamless. Support for my users has become significantly easier as I can use Ubuntu tools to carry out the tasks on hand from a central location. 

Ubuntu and other Unix operating systems have been community-driven so it's got tools that are community inspired and developed, with it being open-source, the cost is no longer a factor either and we can focus on providing the best possible solution to our customers. 

We use Ubuntu Linux for deployments, infrastructure tasks, and for our developers. It is currently both on-prem and in the cloud. On-prem, there are a handful of machines and approximately 15 virtual machines in the cloud.

Most of the machines are somewhat tied to development purposes. We use it to host GitLab and an artifact repository. We also use it for mail relay to address some shortcomings in the exchange that we experience.

Ubuntu Linux is also used for Kubernetes and Docker development and production tasks. Most of the use cases of Ubuntu Linux are infrastructure related, with approximately 10 to 15 developers who also use it as a desktop.

For total number of users, there are 150 developers working with this solution and many more that use more specific services that are hosted on Ubuntu.

We plan to deploy a major application which will cater to all our testing and quality assurance people, which runs on Ubuntu on Linux.

The most valuable features of Ubuntu Linux is the reliability, the ease of package management, and the ease of upgrading from one version to the next. 

With Ubuntu Linux you can set it and forget it.  It requires low amount of administrative overhead.

We use the solution as a backend production server. We run our Docker containers on Ubuntu. We mainly use it for automotive charging software.

The product is easy to use. I like the tool’s performance and availability.

It is mainly a LAMP server with Apache, MySQL, PHP, and other things for the students to do their web development stuff. It's all done up with LDAP capabilities of getting into it. The web server side is open to the internet, so they can sit at home, VPN in, and do all their work. They can actually see what the public-facing side ends up looking like. Then we've got our main learning management system because we do our own self-hosted Moodle instance kind of thing. It's all running on a Linux server and doing well. Our DNS servers and things like that are all separate. Two of them are internet-facing, and one of them is internal.

I am very close to its latest version. I try and stick to using the long-term release versions, like every second year when they release the new long-term release one. So, I have some servers that are actually on 20.04, but I've got a web server at home that's on 16.04. I've got Nextcloud and things like that on that server, so I'm afraid to do a full load upgrade on it because I don't want to break anything. That's why I wish I had it set up as a virtual machine that I could take a snapshot of and blow it up and go, "Oh, okay. I'll revert." We can't do that with the hardware box.

In terms of its deployment, at work, I do everything on-premises in VMware vSphere itself. I work with the IT program at the university. It is an Applied Systems one, so it is a two-year diploma program. I've got a whole bunch of different servers set up for them, and it is a mix. Our domain itself is with Active Directory, and everything is Windows, and then just about everything else is running on Linux servers. Our VPN is also Windows because it makes it simpler for users to connect easily. You don't have to download keys and install them and then be able to talk to OpenVPN properly.

I like the fact that I can make it very secure with my own knowledge, which makes it different from Windows that does things in the background by magic, and you hope that it's secure. I like the availability of starting with Linux with totally minimal permissions for anybody and then increasing it on an as-needed basis. This is probably the most important to me. That's where I also love CentOS for Linux because you do a minimal install, and then there is a whole bunch of stuff you can't do without installing packages, which is quite nice in some ways and painful in other ways.

I like the versatility of it. When I first started here, which was like eight years ago, we were running some stuff as virtual machines inside a Linux host instead of doing it with VMware. Then we finally got VMware licensing, but before that, we were doing some virtual machines within Linux itself, and it was working quite well.
