Overview of this book

<p>Django is a high-level Python web framework that was developed by a fast-moving online-news operation to meet the stringent twin challenges of newsroom deadlines and the needs of web developers. It provides an excellent basis to build e-commerce websites because it can be deployed fast and it responds quickly to changes due to its ability to handle content problems. Django with its proven strengths is all you need to build powerful e-commerce applications with a competitive edge. <br /><br />This book explores how the Django web framework and its related technologies can power the next leap forward for e-commerce and business on the Web. It shows you how to build real-world applications using this rapid and powerful development tool.<br /><br />The book will enable you to build a high quality e-commerce site quickly and start making money. It starts with the ambitious task of using Django to build a functional e-commerce store in less than 30 minutes, and then proceeds to enhance this design through the rest of the book. The book covers the basics of an e-commerce platform like product catalogs, shopping carts, and payment processing. By the end of the book, you will be able to enhance the application by adding a fully-functional search engine, generating PDF-based reports, adding interactivity to the user-interface, selling digital goods with micropayments, and managing deployment and maintenance tasks.</p>

Content storage and bandwidth


Storage and bandwidth are important concerns when selling digital goods. Digital content sales tend to involve the transfer of a significant amount of data. Video is especially data intensive, as even with modern compression codecs, file sizes still amount to hundreds of megabytes.

Even a moderately popular video download can quickly consume many gigabytes of bandwidth. Imagine our fictional Cranberry Merchant website decides to sell a short, 20-minute instructional video on Cranberry farming. The video is compressed using a high-performance H.264 codec and is sold as a direct download (as opposed to streaming).

The video quickly becomes a small hit and soon hundreds of amateur Cranberry farmers are clamoring to learn from it. Over 200 downloads were sold in the first day it launched. Each 30-minute, high-definition video file weighs in at 800MB. Video sales consumed 160GB of bandwidth in a single day.

Every web hosting provider offers different bandwidth pricing...
