The document discusses a use case for cloud computing to process mortgage credit risk modeling. A financial company called Primatics used Amazon EC2 to build two versions of their risk modeling platform called Evolv Risk. Version 1.5 was a hosted web solution using EC2, while Version 2 was rebuilt from scratch using GigaSpaces to take advantage of its scalability and cloud integration capabilities. GigaSpaces allowed Primatics to more easily provision resources, implement auto-scaling and failover, and achieve linear scalability compared to their previous in-house solution. This reduced development time and complexity of problems.
