What are your thoughts on Itara's approach to distributed system topology?

Itara aims to simplify the management of distributed systems by providing an explicit, executable layer that represents the system's topology as a directed graph. This allows developers to change service boundaries and communication protocols without altering business logic. It supports event-driven design and aims to be language agnostic, currently implemented in Java with a proof-of-concept in Rust. What challenges do you face in distributed systems, and do you think Itara addresses them effectively?
