ScaleCube

Eliminates single points of failure and bottleneck by using a fully distributed peer-to-peer design, as highlighted in the README's emphasis on high availability for real-time systems.

Provides built-in patterns like fire-and-forget, request-response, and bidirectional streaming via Mono and Flux, enabling low-latency communication ideal for real-time processing.

Offers flexibility with interchangeable transports (e.g., RSocket, Aeron), API gateways (HTTP, WebSocket), and encoders (JSON, Protocol Buffers), reducing vendor lock-in.

Uses the SWIM protocol for zero-configuration peer discovery and load balancing, simplifying cluster management in distributed deployments.
