In order to improve internal and external business processes, and bring them closer to customer-centricity, modern governments are introducing e-Government, based upon service delivery opportunities offered by new communications technologies.
The architecture of e-Government can be divided into: network infrastructure, network publishing, message and information delivery, operating infrastructure, legal and political constrain, standards and protocols of networking, and applications. On the other hand, it can also be divided as G2G (Government to Government), G2B (Government to Business), G2E (Government to Employees), and G2C (Government to Citizen).
