What is most valuable?
I think the most valuable feature for me, as a database professional, is an operating system that has been modified to have more stability in terms of drivers, in terms of the kernel. We have found a lot of problems using other equivalent systems when upgrading the kernel. Using the unbreakable kernel, we have been able to stabilize many systems.
How has it helped my organization?
As an organization I would say that having the same company that provides support for Linux, for the operating system, and also the software on top of it - in my case it's Oracle database - I think that it's closer to having better support, a faster response from support and, of course, better solutions.
What needs improvement?
I think that the only improvement is staying up with the pace of the technology evolution. As long as Oracle Linux supports all the recent technologies, there are really no more innovations it will need. If the technology itself evolves, as long as Oracle Linux supports it, it's the perfect product.
What do I think about the stability of the solution?
You start it and you shut it down only when you need to, really, but it never crashes. I have not experienced the crash of Oracle Linux recently.
What do I think about the scalability of the solution?
Well, depending on what you mean by "scaling," in vertical scaling we have systems at my customers that go up to 700 gigabytes. I don't know if it's the most scaling, but definitely it's more than enough to have good database consolidation on the server.
How are customer service and technical support?
I think it's good. It's not really necessary, too often, to need support for Oracle Linux. Sometimes it depends on hardware drivers, if there is the necessity to have something special. But in general, my impression is that it's stable and we don't need much support.
Which solution did I use previously and why did I switch?
Again, I have to mention that I am an Oracle database professional, so I'm really focused on this technology. Of course, other operating systems often have many more problems in configuration, in stability, they need much more fine tuning. I don't want to mention them but I will say that many customers are trying to switch from, for example, legacy Unix systems to Linux.
How was the initial setup?
We use, of course, a configuration management tool like Chef Puppet nowadays, or Ansible, so it's really easy to maintain the system. But, even installing for just one server, by hand, now is straightforward. It's not a whole day of installing Linux, that's not the case any more.
