EventStream Build Log #1: Static Benchmarking as a Gate for Architecture Decisions

How do you compare software architectures objectively? It's a challenge many teams face. In this series, we're taking a hands-on approach with the EventStream AI Monitor, a platform designed for intelligent event processing in distributed systems. Rather than relying on abstract concepts or gut feelings, we're grounding our decisions in hard data. Our methodology is a phased, systematic evaluation where we fix most variables and isolate the technology under test (such as architecture, database, or framework) to truly understand its characteristics. EventStream AI Monitor is an intelligent layer for monitoring distributed systems. It receives events, applies AI for classification and summarization, and triggers automated actions based on rules. Given the critical nature of such a system, choosing the right foundational technologies is paramount. Our approach is systematic and structured in multiple phases: Phase 1: Compare architectural styles (Hexagonal, Clean, Onion) using fixed techn
