This article describes the architecture, hosting options, data sources and data architecture, but for more basic details and an introduction, please go through Part 1 and Part 2 of my articles.
LightSwitch Architecture
The main architecture of LightSwitch is divided into 3 parts or we can say 2 tiers and 1 source. All these 3 parts are well ordered and work in a linear progressive way, as represented in the following diagram.

Some of the basic guidelines regarding hosting options in LightSwitch are as follows:
- HTML client optimized for operating systems like iOS 5/6, Android v4, WinRT, WIN Phone 8, Desktop Apps and so on. These services can be in browser or out of browser, but in the case of out-of-browser, it will be only valid in Windows and in browser windows and Mac.
- For hosting we require IIS6 but IIS7 is recommended in this case.
- SQL Server support
- LightSwitch SharePoint app can be easily hosted using Azure.
