Service Arrays: Scalable • Multiple Windows Services provide for a scalable system. Services may be started on several servers, spreading processing across servers and providing redundancy. • Windows Services are started with Server StartUp. No login necessary. Windows Services are configured to ‘start-as’ a user that will have necessary EDS system privileges. • Service array allows for plug-in of new services on-the-fly. • Workflow and configuration are data-driven. • Message queue usage is light and quick. Order XML submitted to any queue is consumed as soon as processors are able to do so (any appreciable delay would be solved by starting additional services). Systems Admins (SA) may elect to apply redundant queues with no impact to the EDS. Queues are monitored to determine array performance with threshold excesses reported to SAs. • Orders will be entered into a database and tracked through their life cycles. Allowing for metrics reports and future order warm-starts.
Service Arrays: Expandable • Basic structure includes SQL data driven dispatch of orders, throughout order life cycle, to queues monitored by specific services. • Delivery management is data driven and dependent upon order origination. • The service array design provides for modular processing, ultimately allowing OSC the option to create its own Processing Services. The Service Array Architecture is expandable without, necessarily, future reliance on ASA. • An Automated Validation service exists to test data immediately after acquisition via the EDS’ own request services. Validation orders are processed with a unique ‘client’ ID, allowing SAs to differentiate between operational and validation data orders. Validation order setup is completely data-driven, allowing SAs to specify AOIs for any of the non-tidal/static data sources.
