The document discusses building serverless web applications on IBM Cloud using Apache OpenWhisk. It explains that serverless technologies can save costs for web applications that are not used 24/7 by avoiding maintaining infrastructure and servers. The document provides an example of an end-to-end serverless web application architecture using IBM components like App ID for authentication, Cloudant for the database, and Cloud Object Storage for static resources. It also shares a GitHub link to the sample code.

2. Why?
Many web and mobile web applications are not used 24x7
For those applications there is a good potential to save costs
when using serverless technologies
Plus developers can focus on writing code, rather than
maintaining infrastructure/servers

3. What?
Web applications don’t only need client side code, but also:
Server side business logic
Databases
User directories and authentication
The following sample shows how to build and deploy
end to end web applications with serverless IBM components
