Salesforce Architecture Variants

Overview

Three validated architecture blueprints for Salesforce integrations: Direct API (simple), Event-Driven (scalable), and Middleware/iPaaS (enterprise). Each pattern addresses different scale, latency, and complexity requirements.

Prerequisites

• Understanding of your data volume and sync frequency requirements
• Decision on unidirectional vs bidirectional data flow
• Knowledge of Salesforce edition (affects available features like CDC)

Variant A: Direct API Integration (Simple)

Best for: MVPs, < 50K records/day, single-direction sync
