Cons
"The solution could improve by being more user-friendly.""The GUI interface could always be better.""The YUM install manager can be improved. It is below average as compared to the other install managers. This is the only major problem that I see with CentOS. They should reduce dependency on the YUM manager.""It would be ideal if Red Hat would continue the CentOS versions in an open-source format. They seem to be moving away from that. Now only paid versions are available.""Lacks sufficient security and some coding tools.""The server system is a little bit tough to manage.""The solution could improve by making the management tools better for the DevOps teams. For example, WebEX and Webstacks.""It is challenging to scale the solution when we have to increase the storage capacity from one end."
