This article clarifies the distinct roles of Model (reasoning), Runtime (execution), and Host (user interaction) in AI Agent systems, providing a troubleshooting framework, contract definitions, and architectural guidance to prevent misdiagnosis and improve cross-team alignment.
This article reviews 'Software Architecture: The Hard Parts', highlighting eight key architectural challenges including trade-offs, data-architecture tensions, service granularity, database decomposition, distributed data access, contract design, code reuse, and error handling in distributed systems.
This article explores the role of contracts in software architecture, explaining why architectural-level contract decisions are crucial, comparing strict and loose contracts such as gRPC, REST, and key‑value formats, and introducing consumer‑driven contracts, their trade‑offs, and practical guidelines for reducing coupling and brittleness in microservices.
