Architecture
LeaseWave 4.0 is an n-tiered application rendered wholly via a web browser. Its web, application and database layers can be separated both logically and physically. For business users (client machines), the system is rendered on an Internet Explorer browser. The system is designed with a true service oriented architecture (SOA). Its service layer wraps fully around all its business / middleware components, allowing business functions to be consumed by outside sources via a web service call. LeaseWave is highly scalable: it has been load and performance tested for 1500+ concurrent users.
