Container orchestration has improved performance and resource use but exposes disk space issues

How fast the application runs is one of the biggest advantages for me in Docker, but on the downside, issues to do with space utilization arise sometimes. Since we implemented it, the system really improved and became responsive very fast. When you have limited space, the system tends to crash from time to time, so you have to ensure that you have enough space at any one point. We are using the orchestration feature in Docker. That was the main motive for having orchestration; it helps better manage the containers. I am comparing Docker on CentOS with the one that is running on Ubuntu, and in terms of scaling up, it is easy to work with when it comes to that. That is the main feature I have been benefiting from. Because it was first, we recently did it on Ubuntu, but initially, it was running on CentOS. We were comparing and seeing which one runs better, but I realized on Ubuntu it is much easier to work with. The lightweight architecture on CentOS affects my resource utilization significantly.

Has supported secure application hosting and reliable server management

I find the GUI to be good in Ubuntu Linux, and I appreciate the open SSH. The fact that it is free since it is open and open-source is why I appreciate it and feel it is secured. We have multiple different kinds of support related to Ubuntu Linux, including official support and other options. I am currently using laptops, desktops, and servers, and Ubuntu Linux supports all these devices. If I need it for Raspberry Pi or something similar, I can download another Linux distribution. Ubuntu Linux is scalable, especially for servers. We prefer using Ubuntu Linux Servers rather than Windows. The biggest advantage of Ubuntu Linux for me is that it is open-source, secured, and scalable.
