This chapter took you through deploying and packaging code so that it can be deployed to test and production environments. To speed up serving content, we used CDN-services through SharePoint Online and Microsoft Azure. Normally you would choose either one based on your requirements and user base. Most often you'll resort to using SharePoint Online-based CDN's, as it's slightly easier to configure and will not incur additional costs. For on-premises SharePoint environments, a logical CDN location would be either Azure Storage or an on-premises service, such as a proxy server.
In Chapter 7, Working with SharePoint Content, we'll learn how to use mock data when developing solutions locally, as well as accessing real SharePoint-based data from within your code.
