The Architecture of a Virtual Grid GIS Server
The grid computing technology provides the service oriented architecture for distributed applications.The virtual Grid GIS server is the distributed and interoperable enterprise application GIS architecture running in the grid environment,which integrates heterogeneous GIS platforms.All sorts of legacy GIS platforms join the grid as members of GIS virtual organization.Based on Microkernel we design the ESB and portal GIS service layer,which compose Microkernel GIS.Through web portals,portal GIS services and mediation of service bus,following the principle of SoC,we separate business logic from implementing logic.Microkernel GIS greatly reduces the coupling degree between applications and GIS platforms.The enterprise applications are independent of certain GIS platforms,and making the application developers to pay attention to the business logic.Via configuration and orchestration of a set of fine-grained services,the system creates GIS Business,which acts as a whole WebGIS request when activated.In this way,the system satisfies a business workflow directly and simply,with little or no new code.
