# Sequence diagrams of connecting to enterprise systems (e.g. ERP, WMS)

## Overview of this article

- The **scope** of this article consists of infrastructure sequence diagrams between the Tulip platform components and third-party enterprise systems (e.g. an ERP, WMS, etc...).
- **Audience:**
  - Tulip solution developers
  - I.T. engineers
- The **purpose** of this article is to inform the audience of their Tulip solution's dependencies on:
  - reliable connectivity to Tulip cloud infrastructure
  - performant and reliable local network infrastructure
  - reliability and performance of connected systems
- **Tulip-Internal Latency** - As a back-of-the-napkin approximation, assume each instance of 'Tulip-Internal Latency' is approximately 100 milliseconds.
