Needs advice

Hello guys

I am confused between choosing CentOS7 or centos8 for OpenStack tripleo undercloud deployment. Which one should I use? There is another option to use OpenStack, Ubuntu, or MicroStack.

We wanted to use this deployment to build our home cloud or private cloud infrastructure. I heard that centOS is always the best choice through a little research, but still not sure. As centos8 from Redhat is not supported for OpenStack tripleo deployments anymore, I had to upgrade to CentosStream.

While I'm not overly familiar with OpenStack I'd go with Ubuntu given that CentOS is being discontinued. Rocky Linux might be an option sometime in the future, which is a project started by the founder of the CentOS project.

I believe Canonical is going to be around and supporting the platform for at least the lifecycle of your system, whereas CentOS would mean that you are possibly going to be left unsupported after a certain date.

Personally, I haven't had a bad experience with either CentOS, or Ubuntu for the last 5 years, so the choice of distribution hasn't been overly significant and comes down to preference.

Cheers Dean

I've been providing software for the Navy that was intended to run on CentOS 7, which is the LTS (long-term support) version for several more years, with CentOS 8 having a lifespan ending this year. However, some companies (namely Microsoft) seem to be moving on from CentOS 7 to 8, at least with VS Code which dropped support for 7, in favor of 8, which leaves CentOS users in a horrible mess for shipping enterprise products. As a result, I've started moving to Ubuntu 20.04 LTS as the target environment, were possible. Support for Fedora 32 ended *today*. The Linux world is going through a bit of fast changes currently and I suspect the most stable place to be us Ubuntu 20.04 LTS, which will be supported into April 2030.
