This document outlines a presentation about architecting cloud-only solutions using Office 365, Azure, and SharePoint Online. The presentation discusses challenges like performance, scalability, and identity management that the presenter encountered with their company's SaaS offering. It describes evolving approaches to application development from traditional to modern architectures. The presenter advocates applying domain-driven design principles and moving business logic and data access layers out of SharePoint and into tools like Azure Functions and API Apps for improved scalability, robustness, and maintenance in cloud-only solutions.

What did we do
• MVC web part talks directly to datasource
• (SharePoint Online REST API)
• It works!
• No code reusability
•What are our options?
• Move the code for wine adding and calculation out
• Apply architecture
