Designing and Implementing a Multiuser Apps Platform
The document discusses the design and implementation of Usergrid, a multi-tenant, multi-server application platform built using Java, Spring, Jersey, Jackson, and Cassandra to provide user management, data storage, analytics and other features through a RESTful API in a scalable way that allows multiple teams and applications to easily build and deploy mobile and web apps. The document outlines some of the challenges in building such a platform and how Usergrid addresses issues like consistency, API design, permissions, built-in logic and operations.
