Observable Reflective Architecture (ORA) is a framework for designing systems that are explainable from the inside out. This series covers the principles, architectural layers, and technical pillars that make observability and reflectivity possible by design.
ORA stands for Observable Reflective Architecture. This chapter introduces the three properties that ORA designs for and sets the stage for the series ahead.
Observability becomes more powerful when architecture supports it. This chapter explores what observability requires, how wide events form its substrate, and how ORA amplifies what modern observability tooling can achieve.
Reflectivity is the property that allows a system to understand its own behaviour over time. This chapter explores how events become the foundation for reasoning, learning, and self-improvement.
Architecture means different things depending on who you ask. This chapter examines the four states of architecture, the danger of misalignment, and why ORA treats architecture as a first-class concern.
ORA is built around three architectural layers: goals, capabilities, and pillars. This chapter defines the layered model and shows how each layer supports the one above it.
A deep dive into the three technical pillars: event-sourced, message-driven, and read-write decoupled. This chapter covers consistency boundaries, formal models, and the design tradeoffs behind each pillar.
How does ORA compare to other architectural styles? This chapter contrasts ORA against CDC-powered systems, N-tier architecture, and async spaghetti across goals, capabilities, and pillars.
