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 good automation features
Pros and Cons
- "There are many good automation features in Ubuntu."
- "Management monitoring and interface could be better."
What is our primary use case?
How has it helped my organization?
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.
What is most valuable?
There are many good automation features in Ubuntu. For example, there is a new version of Netplan Fortune which is a network manager and it is very good at managing a network of virtual machines. Ubuntu is optimized, which makes it really nice, as we can optimize Ubuntu as much as we want. For example, I had a good experience in traffic management, as I could optimize the system and Linux to make it efficient. Ubuntu is easy to obtain information for because there is a lot of documentation, and there is also a large community where you can have questions answered. Linux systems like Ubuntu and Centos enable you to work quickly, and easily. This includes installing a lot of programs, easily, as and when you need them. For example, when we are deploying the OpenStack operating system, we can use many sources, such as Galera Cluster. All of these packages are pre-compiled and pre-deployed on operating systems like Ubuntu.
What needs improvement?
The new releases of OpenStack are much faster than Ubuntu. However, the commitment of the OpenStack project is not supported in Ubuntu in the first instance. If the Ubuntu community can package and manage new releases of OpenStack packages, it will be really good. Management monitoring and interface could be better. I also feel it could be improved overall in terms of the dashboard, technical support, pricing, stability, scalability, and performance. They could try to package more new releases of OpenStack, and that would be much better.
For how long have I used the solution?
Personally, I have been working 15 years in Linux including a role as a Linux System Administrator. I have experience in Linux concepts including system programming and cloud computing recently. I also know about storage systems. OpenStack is the last thing I have been working on, deploying to the cloud about 5 years ago. It is the main product I've been working with. I do not have experience in Red Hat Operating System, but Debian, Ubuntu, Census are the main operating systems I have been working with.
What do I think about the stability of the solution?
The stability of Ubuntu is good. The most important aspect is that you can use the LTS versions of Ubuntu. We can have upgrades of software for many years and obtain support from Ubuntu. Stability is important for a Linux administrator In general Ubuntu or even CentOS does not have any problems with stability and you can use it for many years. I have used it for 3 or 4 years continuously and I did not encounter a serious issue at that time.
What do I think about the scalability of the solution?
I have set up and deployed Ubuntu with Ubuntu MAAS installation. This was a very useful service that Ubuntu offered to us. I deployed my server with my coworkers and we set up many operating systems at the data centres within a few minutes. Scalability in terms of a service layer is really good. You can install and deploy on many different types of hardware. Most of my experiences are setting and deploying Ubuntu on HP generation of 7, 8 and 9 servers, from the DL38 server, HP DL38 to DL36, 316 servers. We use it as much as we want. Regarding the scalability of Ubuntu, most of our coworkers are using Ubuntu as client servers. They are based in Iran. Ubuntu-based operating systems are really popular in Iran.
How are customer service and technical support?
As we are in Iran and because of sanctions, we don't have a support opportunity. So we try to use it to learn what we can and consult the documentation. We don't have technical support here and we have to support it ourselves. I'm using most of my time to read the documentation and fix problems. We don't have technical support in Iran because of sanctions.
Which solution did I use previously and why did I switch?
I have previously been involved with Centos. My most experience is in private clouds, and I've been deploying Ubuntu Linux and OpenStack. I set this up at the Ferdowsi University of Mashhad for high-performance computing. However, that was about five years ago. Last year in my new company, I deployed OpenStack for a public cloud. And we are going to use it for some of our customers.
How was the initial setup?
Also, partitioning and deploying Ubuntu in the cloud is really simple and easy. We create a base image of Ubuntu or maybe use a pre-built image built in Asia from ubuntu.com to our cloud. I have a lot of experience from many years ago installing Ubuntu and partitioning using LVM partitioning. For example, Ubuntu supports several files systems for use with products such as Excel. These are the main file systems I use in Ubuntu and LVM management in Ubuntu is really simple. Ubuntu installation is really simple, even for newbie users. The installation of drivers can sometimes be difficult, but otherwise, it is an easy setup.
What's my experience with pricing, setup cost, and licensing?
I prefer to use an open-source license rather than proprietary licenses. Ubuntu is very well documented. It is also manageable and financially affordable.
Which other solutions did I evaluate?
We previously evaluated Centos and OpenStack.
What other advice do I have?
Ubuntu has improved driver support and the installation of Ubuntu is really fast and easy. I recommend it to everyone. I would recommend Ubuntu over any other operating system. Ubuntu is useful for a variety of challenges, and issues. I would rate Ubuntu as 9 out of 10. It has good support and can be deployed on a cloud such as OpenStack. Ubuntu thinks about its customers and really helps them to achieve what they want. The freely available support resources of Ubuntu are really good. The good use of documentation and community forums are the major things that Ubuntu has succeeded. Ubuntu has done a good job of supporting their releases of lifetime services. I think it's a little bit better than CentOS.
Which deployment model are you using for this solution?
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?
