## Headquarters Enterprise Messaging Initiative(HEMI)

**Architectural Overview**

**Notes:**
Introduction
NASA, like many large enterprises, was having difficulty managing the dynamic collaboration content across the agency. There were many platforms with inconsistent backup services, poor integration, and no metadata indicating the relevance, value, or status of the content. UNITeS Engineering turned to SharePoint Products and Technologies to solve these problems.
SharePoint Products and Technologies work together to deliver highly scalable collaboration solutions with flexible deployment and management tools. The collaboration solution addresses four distinct business needs.
Personal storage
Team collaboration
Group and division portals
Enterprise services
