SCTP [1] is there to provide a reliable message based protocol. And it does work inside a datacenter. The issue is outside the datacenter: it doesn't work reliably across the Internet due to middle boxes dumping anything not TCP or UDP...
But inside a controlled environment like a datacenter, it works. It's been used in the telecommunication world to carry control messages in the radio access and core networks for example. So it's been tested at scale for critical applications.
