  1. 備援機制草案Redundancy System Draft

  2. 備援方式 • 1.Application HOT StandBy備援機制 (GIS/WEBPORTAL ) • 2.DB HA機制

  3. 目前規劃硬體架構 伺服器監控主機/ WhatsUp intranet GIS Server/ 地址定位API Web Portal FET DMZ DB Internet AP Users data FET NEDB Synchronization Data

  4. 1.Application HOT StandBy • 將原有GIS及WebPortal架構改為一組AP Server備援主機。 • 限制：AP Server需有一組domain name，在DNS設定備援主機為domain name的第二指向IP。 參考價格：75萬元

  5. 硬體架構變更 伺服器監控主機/ WhatsUp intranet AP Server FET DMZ DB AP Server AP Users data FET NEDB Synchronization Data

  6. 2.DB HA機制 • 新購一組DB主機，將DB設為Cluster，當DB異常時透過Windows Cluster Service切換至另一台DB Server 參考價格：75萬元

  7. 硬體架構變更 伺服器監控主機/ WhatsUp intranet GIS Server/ 地址定位API Web Portal FET DMZ DB Cluster AP Users data FET NEDB Synchronization Data
