C4 Model
A set of four nested diagram levels — context, container, component, code — that keeps each diagram at one consistent level of abstraction.
Context Window
The maximum number of tokens a model can attend to in one request, holding the system prompt, history, retrieved context, tools and the answer.
Model Context Protocol
An open protocol that standardises how AI applications connect to external tools, data sources and prompts.
Architecture Decision Record
A short, immutable document capturing one architectural decision, its context, the alternatives, and its consequences.
Cross-Zone Data Transfer
Charges incurred when data moves between availability zones within a region — invisible on architecture diagrams and a recurring surprise on cloud bills.
Data-Flow Diagram
A diagram of how data moves between processes, stores and external entities, with trust boundaries drawn on it.
Retrieval-Augmented Generation
Retrieving relevant documents at query time and putting them in the model's context, so answers are grounded in your data rather than in training data.
Role Explosion
The proliferation of narrowly-scoped roles that occurs when RBAC is used to express rules that actually depend on context.
Sequence Diagram
A diagram showing the ordered exchange of messages between participants over time, used to make an interaction's control flow and failure points explicit.
Context Diagrams
The system as one box, with its users and external systems.
C4 Model
Context, container, component and code as four separate diagrams.
Architecture Diagrams
Choosing an audience and refusing to mix levels of abstraction.
Data-Flow Diagrams
Following the data across trust boundaries rather than the calls.
Deployment Diagrams
What runs where, in which zone, behind which boundary.
Sequence Diagrams
Ordered message exchange, and walking the failure of each arrow.
AI Cost Management
Token accounting, routing, caching and the context-window budget.
AI Observability
Logging prompts, versions, retrieved context and cost per request.
Architecture Decision Records
One decision, its context, alternatives and consequences, kept immutable.
Domain-Driven Design
Ubiquitous language, bounded contexts and context mapping.
Writing Decision Records
Context, alternatives and consequences, written once and never edited.
