e-Government improves the efficiency of public administration, increasing transparency, deducing administrative corruption, improving service delivery, citizen’s empowerment and improving government finance. The private cloud provides the ideal environment for scalable e-Government applications because of its scalable and elastic characteristics. The scalability can be achieved horizontally and vertically within short time in cloud environment. During design and development phase of application, special consideration is needed for scalability and high availability on Application and database layer. Application layer high availability and scalability can be achieved with a server load balancer. Database layer high availability and scalability can be done by database sharding within a database fail-over cluster. In this paper, we propose a scalable highly available architecture for e-Governance applications on private cloud environment.
