The storefront is built using state-of-the-art technologies such as:

1. Castle Windsor – a best-of-breed, mature Inversion of Control container available for .NET. For more information, see the Castle website.
2. Bootstrap 3.2 – a free collection of tools for creating websites and web applications. It contains HTML and CSS-based design templates for typography, forms, buttons, navigation, and other interface components, as well as optional JavaScript extensions. In the Storefront, Bootstrap HTML and CSS design templates are the output of the Sitecore renderings. For more information, see the getBootstrap website.

Business Tools - The web-based Sitecore tools that are used by merchandisers, marketers, procurement, and customer support personnel to manage commerce content. These tools include:

1. Customer and Order Manager (COM) - This tool is new in release 8.2.1, and is integrated with the Commerce Engine via its CommerceAuthoring API.
2. Pricing and Promotions Manager (PPM) - This tool is new in release 8.2.1, and integrated with the Commerce Engine via its CommerceAuthoring API.
3. Merchandising Manager (MM) - An existing tool for managing the catalog. It integrates with Commerce Server, where catalog management is currently hosted. MM will be rebuilt in a future release when Commerce Server is phased out, and will integrate with the Commerce Engine in the same way as the other tools.
