Synchronous vs Asynchronous Interaction Model Template
Documenting when to use synchronous versus asynchronous communication, with selection criteria and trade-off analysis
The Synchronous vs Asynchronous Interaction Model template provides a structured approach to documenting when to use synchronous versus asynchronous communication, with selection criteria and trade-off analysis.
Template Sections
This template includes 7 sections.
Interaction Model Overview
Describe the overall approach to inter-service communication and the factors that determine whether an interaction...
Synchronous vs Asynchronous Trade-offs
Compare synchronous and asynchronous approaches across latency, coupling, reliability, complexity, debugging, and cost
System Interaction Model
Diagram section
Interaction Selection Principles
State the principles guiding sync vs async selection (e.g., prefer async for cross-domain, sync for user-facing reads)
Protocol Constraints
Document constraints on protocol selection (e.g., legacy systems only support SOAP, regulatory requirement for...
Responsiveness Scenario
Document a quality attribute scenario showing how the interaction model affects user-perceived response times
Hybrid Patterns
Describe scenarios where a combination of synchronous and asynchronous patterns is appropriate (e.g., sync command with...
