GCNet ICT Architecture
The GCNet ICT Architecture is fully centralized and interconnection with the GCMS and the
Port System of the Tema Port Authority. Government agencies’ business processes are
integrated with end-to-end business processes integration.
The architecture three tiers based–web servers, application servers and common data storage.
For load balancing the high availability concept (clustering) and visualization is used. The
GCNet SW infrastructure consists of two mirrored sites with 98% availability of services. Data
warehouse and business intelligence is used for reporting and analysis services, covering both,
GCMS and GCMS.
At this stage, paper and digital processes co-exist as the digital signature is not used in the
GNSW system, although the legal framework for e-documents and signatures is in place since
2008. Customs validation and clearance are still paper based, and the customs declaration (Bill
of Entry) and all supporting documents must be presented in paper. The digital signature is
however used for system-to-system communication (GNSW, GCMS, commercial banks and
National Bank of Ghana – Treasury.
