Grid computing/XTP scenario
This scenario shows how the business pattern for grid computing and Extreme Transaction Processing (XTP) technologies described in Chapter 1 can be implemented.
Implementing the grid computing business pattern
The grid computing business pattern can be implemented using a data grid framework and is shown in the following diagram:
Trigger:
An application makes a change to an object in the distributed cache.
Primary flow:
1. The data grid ensures that the modified object in the distributed cache is updated.
2. The relevant backup data is updated.
3. Depending on the topology of the cache, the data may be distributed across the entire cluster or only across certain computers.
4. Applications can register their interest on changes to data by applying a suitable filter. In this case, they receive an event whenever the data has been changed.
