E-Governance is one of the important Information and Communication Technology (ICT) enabled administrative mechanism to affect deliverables to all its stakeholders. It is expected to provide reliable services to all, anywhere, anytime, 24 by 7, with acceptable levels of performance. There are various e-governance projects which have been successfully implemented in different part of India. Citizens have actually started adopting such services in full swing. It has been noticed that some of the e-governance projects have not been able to meet up the growing expectations of the stakeholders pertaining to the constraints like performance, availability, data management, concurrency, security and efficiency. Choice of appropriate IT infrastructure plays a vital role in fulfilling the goals of various e-governance projects. Looking at the current usage pattern of such project there is lot of scope of integration of newer technologies for reinventing the traditional system. Cloud computing is a new genre of computing which has a potential to build and deploy applications and services via internet targeting the needs large sets of geographically dispersed users by delivering integrated functionality across the masses and the Web. Adoption of cloud based architecture will help in embedding techniques like virtualization of critical resources for instant service deployment and optimizing resource utilization. This paper provide a case study based approach to anticipate cloud based implementation in the existing infrastructure to cope up with the issues like fault tolerance, high availability, high volume query processing request, central data centre management, data security etc. It reveals the analysis of Kalyan Dombivli Municipal Corporation (KDMC) e-governance project with its IT architecture. At last the paper proposes a cloud based implementation model for dealing with the above mentioned issues along with its advantages.
