App42 Cloud API is equipped with CDN as a service which can be used through File upload APIs. Whenever a file/photo is uploaded using cloud APIs, it gets stored in our CDN and the url you will get would be like http://cdn.shephertz.com/XXXXXXXXXXXXXXXXX/XXXXXXXXXXXXXX
File upload APIs are designed to handle the file for app users as well as files for your app. Using these APIs one can build a SaaS based application which can provide file storage for their user on the cloud.
Using File upload in the app is pretty straight forward, it accepts file path or input stream of file along with other input like user name, file name and description. Rest of the complexity is taken care by App42 platform which includes security, multipart request creation, data parsing, scalability and so on.
