Context Engineering Architecture 2.0
From service design to context design
Slide contents
1. Context Engineering Architecture 2.0
From service design to context design
2. What this article is about
Analogy → enterprise strategy
Part 1: 'LLM service' lens.
Part 2: Architecture 1.0 vs 2.0.
Part 3: signals 2025–2026.
Parts 4–5: flexibility cost and strategy.
3. 01. Historical Analogy
Why 'just add an LLM service' is too narrow a lens
4. Architectural shifts are underestimated
5. 02. Two Architecture Modes
Architecture 1.0 — deterministic systems, Architecture 2.0 — managing uncertainty
6. Architecture 1.0 vs 2.0
7. 03. Industry Signals 2025–2026
7 trends already changing architecture
8. Context and durable execution
9. Memory and tool layer
10. Evaluation and security
11. Event-driven + cognitive and scale in tokens
12. 04. Architecture 2.0 is not free
Each of the 7 trends creates a new class of risks
13. Flexibility is not free
14. 05. Enterprise Strategy
AI as a control plane over legacy, platform, and knowledge systems
15. Control layer over the landscape
16. What to borrow from where
17. Verdict
From fixed paths to context
Design unit: context, decisions, execution.
Architecture 2.0 manages uncertainty over 1.0.
Enterprise: AI = control plane over legacy.
