Scaling
The Art of Scalability (http://theartofscalability.com/) book uses a scale cube model to describe three primary scaling patterns for an application, as shown in the following diagram. The x-axis of the cube represents horizontal scaling; that is, deploying the same instance of the application by just cloning them and front-ending by a load balancer to distribute the load evenly among the instances. This scaling pattern is quite common for handling a high number of service requests. The z-axis of the cube addresses scaling by data partitioning. In this case, each application instance deals with only a subset of data. This scaling pattern is particularly useful for applications where the persistence layer becomes a bottleneck:
