I don't think these guys understand what this cert is for. If your "cloud" is servers running VMs, you would likely want enterprise reliability. If you are running software that cannot be checkpointed well (so failure is serious, rather than just resuming off some checkpoint), you'd want reliability.
This is not for that kind of software. This is for the Google and Facebook type of "cloud", which assumes failures WILL happen -- the software performs data integrity checks are performed, data is stored at least in duplicate, and it tolerates a system failing, resuming whatever work it was doing on another system. In this case, I would not want to spend on enterprise reliability features.
