The document discusses Backend as a Service (BaaS) and how it can be used to quickly create backends for mobile and web applications in minutes without having to build the backend infrastructure from scratch. It provides examples of how BaaS providers like apiOmat offer data storage, APIs, SDKs for common platforms, and other features that allow developers to focus on building just the application logic. The document argues that using a BaaS can significantly reduce development costs and time compared to developing a custom backend.
