RBD is a specialized, long-lived product; relative to mainstream SaaS platforms, public review volume is very limited. In this research pass:
Public community discussion specific to RBD/EGL is limited relative to mainstream development stacks. Historical signals indicate a small, specialized user community rather than a large active ecosystem.
No explicit modern customer case studies with named companies and independently corroborated quantified outcomes were surfaced in the accessible materials.
IBM hosts deployment scenario and datasheet collateral that describe RBD use scenarios and claimed productivity or flexibility outcomes.
